3.9 to 5.0 litre

[Lambo]

Hey Guys,

I have a 1995 Disco with a standard 3.9 V8 and auto box in it. I have been considering dropping a 5.0 litre Holden V8 and Turbo 700 gearbox in. Anybody ever tried this and can tell me what are the potential pitfalls.(probably heaps).

Dont bother going GM unless you have lots of money and a lot of time
Its a lot easier to stroke the Rover V8 out to 5.0 link above

And you dont need an engineers approval cause its the factory engine

[rovercare]

Yea don't do it, cause I've never tried it:rolleyes:

Downfall is, no adaptor for the auto to transfer case, can mount the 5L infront of the ZF, it'll handle it stock, but if you plan on upping the HP after that, it won't take to well and are big bucks to build tough

They are an easy engine to use in a conversion

I'd suggest 6L 4L80E:twisted:

What did the 4L80E come with? Was that the 6 litre tranny or an HSV part etc?

[400HPONGAS]

The 4L80E you need comes from a Suburban . Im doing the same , sticking in a Holden V8 engine , The rover 5 litre is gutless pile of crap compared to the Holden and by the time you have built it will cost more than the Holden V8 . and last a quarter of the time/Kilometers . THe only way you get any sort of Half decent power out of any rover V8 is to supercharge/turbo it . As has been stated forget the T700/4L60E they simply dont fit . (easily)

Are you talking about the Holden 4.2 or 5 litre V8? From what I have read, both and especially the former were regarded as being rubbish engines. Poorly designed and in need of a rebuild after 100,000 miles or less. There was also a problem with the 5.7 litre Gen III where piston slap resulted in large numbers of engines requiring a rebuild while under warranty.

A well maintained Rover V8 will run for more than 30 years so add another and that will drive you till your driver's license is revoked.

Somehow I don't think so re the holden V8. :D

[TerryO]

I'd guess the Holden V8 would weigh quite a lot more then the Rover V8 does which wouldn't I guess be such a good thing for serious off road usage if that is what it is for.

My experience with the 308 Holden engine is it was a very reliable but totally unimpressive powerwise bit of gear. Of course there are lots of go fast bits for them if you want to spend the money.

I wouldn't waste my time with the 253, it was dog slow standard. I know plenty of guys who got them to go quite fast for what they were but they ended up being revvers with little torque.

I also have had several 5.7 Chevies both as standard tune engines in various Holdens and as the better free flowing versions in HSV's, the last one was a 6.2 in a HSV.

I good strong 5.7 is a hard engine to go past in my book and they would be far more affordable compared to either the 6.0 or 6.2. Sure the 6.2 was fast but from memory it wasnt much of a torque monster given its size. For 4x4 applications I can't see why anyone would want a top end engine.

The other thing is with the later model Chevies they are aluminium so would weight about the same weight as the Rover.

Of course if you have an old Statesman sitting out the back paddock rusting away with a 308 in it then that would be the go.

Personally in my very limited experience with Rovers I would still get a recoed 4.6 and simply drop that in even though they aren't as powerful as a Chevy or a modded 308 but chances are they wouldn't break anything behind them. Everything with a 4.6 bolts together with your Disco and there is a lot less hassles and while I'm told you still need to get them engineered to be road legal in reality who is going to know unless they check engine numbers. A Holden or Chev V8 will stand out like dogs balls.

This is just my opinion but we all know that opinions are like arseholes everyone has one ...still some smell better then others.

Good luck.


cheers,
Terry

How much would it cost to build a good, reliable 4.6 - $6k?

slipped liner block for rebuild,from free up to - $400
top hatted - $1500
head work $500 - $1000
block / crank / rod machining - $500
new pistons, rings, bolts etc - $500
cam - $200
oil pump - $300
manifold / efi setup / computer - $500
gaskets and other stuff - $1000

just guessing at those figures,

So 6k+ and thats doing all the assembly, checking yourself, no warranty
A 4.6 is good for a drivable 230hp???

How much would a holden / chev conversion cost all up, engineered?


I'd just put a Thor manifold on the 3.9 for a few hundred $$ and go on a holliday with the money you didn't spend. Sucking down umbrelladrinks in the tropics really puts the quest for more power into perspective.

[TerryO]

Recoed 4.6 with all the gear you describe including top hat liners plus a decent cam from TRS for about $4.5K exchange and from memory quite a few more claimed ponies then 230, I seem to remember about 270ish as the number quoted.

The only thing is if his engine is stuffed then a new inlet manifold won't make much difference and he won't have a car to drive to the airport to go on a holiday.

cheers,
Terry

[steve_35]

If your only looking at 230hp for the 4.6 there are a few different way to get around that out of a 3.9

One of those CRS blowers is good for about 40hp on a v8 and that is all through the rev range basically
Extractors cam bigger injectors and a ECU upgrade is good for about 25-30hp but the more violent the cam the less usable it is
Not sure about those Thor manifolds but swapping the top plenum and throttle body is always a nice touch

Thanks, $4.5k thats a pretty good price :cool:
I reckon 230hp is more than enough, 270hp yep, but at what revs?
you could build a 3.5 to put out 400+hp, wouldn't want to drive it anywhere though.

I just put a thor on the 3.5, I like it alot :cool: I actually like the little rover v8 now. I don't know if going to the older 3.9 style manifold would've been just as good or even better though?

[TerryO]

In all seriousness my 94 model D1 3.9 with headers and full system that also has a Unichip fitted blows the doors off of my standard 4.0 D2a.

If you speak to TRS and tell them you want a recoed 4.6 for a Disco they will fit a high torgue cam. I believe they offer several options and usually have rebuilt engines sitting on the shelf ready to go out.

I believe quite a number of Aulro members over time have fitted them but I never found a post to date that says much about how they go or not.

These are long engines, you need a sump, starter, inlet manifolds etc.

Now all I have to do is buy one myself rather then just talking about it.

Terry

Ron sorry but that is absolute BS. Obviously you have never owned either. There would be very few Rover V8s that have not had a rebuild or repairs at all.
The 4.2 (red) was a harder revving engine, I still have one in my Torana. The 5 litre red engine was also a great engine, a lot depended on mods done and this was the issue and where the time bomb issue came from. Many people did cheap and inappropriate mods for horsepower and not longevity, hence they would self destruct, just like any race engine built cheap for horsepower. If built correctly they will last but like any engine Holden, Chevy, Ford or Mopar if used outside of standard specs or application and modded for cheap horsepower rather than longevity they will not last. This goes for the Rover V8 as well which is so old and a Buick/GM design anyway. The thing with these engines is they are easy to work on.
The later 5 litre injected engine is also a great engine if used correctly. We had one in a wagon that used to hammer and is still going strong now in a VT (not ours anymore) and would go better, harder and get better fuel economy than our Statesman 5.7 litre.
The thing you need to remember is petrol engines are designed different to diesel engines and usually have more of a finite life, but having said that I have seen Holden red engines in both 6cyl and V8 do more than 500,000kms in standard form if treated right. Have even seen a taxi with a 4.2 do over 1 million kms without an engine change.
People often forget things like rings and bearings are designed to wear. I have known a number of diesel engines that have not lasted 50,000kms.

If we are talking standard engines, then generally they will last if maintained, but at some point will have to be replaced or rebuilt. Go outside the intended parameters and things change drastically. I had a RRC with a Stroker 4.2 and that was reliable, but still had the Rover oil leaks so gaskets were always an issue as were lifters. Same in most V8s. But take it out to 5 litres which can be done easily and things change depending on you cash flow. If you have the money to do one up like a TVR 5litre then of course it will last, but do it on the cheap like most people do an it will not, just like any Holden,Ford,Chev,Mopar.
Part of the red engine time bomb reputation came from the 80;s were they were prolific and most people would just put big cams and carbies on eventually resulting in component failure elswhere. Because the red Holden motor was so prolific you got to hear about the failures, happend in the Ford 302's and 351's as well, just the Ford Freaks were generally a lot more sheepish about it.
I did pop a 4.2 red but that was because the oil pump was not primed by said mech.
Also red line any engine often and see how long it lasts. A big part of engine failures I saw were that idiots would be redlining and valve bouncing them at the drags, hence why we often see rev limiters now.

Hello Craig,

No probs, no offence taken...I was stiring the pot so to speak. It is true that I have never owned either, and that is a choice that I made. There were problems with the 5.7 Gen III as doing some digging will reveal.

If Holden felt that the 4.2 and 5.0 were such great engines with loads of potential they would have continued their production, but as we know that didn't happen for one reason or another. In unleaded form, both were dismal in their power and torque delivery. I appreciate that many mods could be undertaken just as many mods can be undertaken with a Rover V8.

The Rover V8 was in production from circa 1967 till 2004 and now the block is manufactured under license by Cosworth, so clearly it was and is an outstanding engine.

My 3.5 V8 ran without ever leaving me stranded for 33 years until being retired. By all accounts I could have installed a new camshaft, bearing etc and continued for another 33 years.

It just irks me when people pile criticism on what is without doubt one of the best V8 engines ever made...43 years and counting.

Ron.

My 3.5 is also still going strong - but i dont think you'll get much support when you start using long lasting 3.9, 4.0 and especially 4.6 in the same sentence :D

[steve_35]

Im only new to the rover V8 but i have had several 253's 308's and a 5.0 or 304

In my opinion the Rover V8 is a heaps better motor lighter sounds better as far as power goes my stock 3.9 efi runs smoother and revs easier than any of the holdens i have had and is just as powerful

Dont you like the Rover V8

[BigJon]

I love my 3.9 Rover V8, but it is gutless and thirsty compared to my last EFI 5 litre.

I am intending to rebuild my 3.5 with a stroker crank and I am keen to fit Delco injection as well.

[jazzaD1]

i agree, i like the 3.5 in my disco, but would swap it in a heart beat for something with more torque and efficiency

[400HPONGAS]

Its obvious hat not many have slightest clue about Hoolden V8s or even thier woeful Rover V8/s ,( a lessom in Basic head design/layout is required to understand way Rover V8 are such absolute crap) I can get 500 HP NA out of of hoden V8 easily aand still be very streetable/ offroadable (Cams at 233@50) , Sure they are strokers 355/383/396 but still way cheaper to build and 10 times more reliable than Rover V8's at at a ****weak 300 FWHP . A HoldenV8 is made in Australia , no Chev crap !!

[jazzaD1]

the thing stopping me dropping in a 304 EFI or similar is the fact i would like to keep it manual, and the LT77 i have in the disco is not up to the task

[steve_35]

500hp from an old 308 id like to see that i was only ever able to squeeze around 350hp out of them and that cost over $6000 10-15 years ago

[400HPONGAS]

Steve 35 , way back in 1974 , holden 308;s were making 400fwhp out of a 308 !!!
Dont know whom built your enginss . but they definately have problems .PS have Holden 308'd making 700HP Naturally aspirated . (You must realise that they have stroker kits fitted up to 400CI) Do ypu know that a standard VN head can flow over 450 HP ? My Head Porter takes them to 650HP (Potential)

average quarter 10.2 and 128mph.

reckon that pretty close to 500hp?

where are all the rover V8's in motor sport in aust? ...imagine that for a class the discovery cup...they could run at the tail end of touring NC so they wouldnt be lapped by the EH's:p

So getting back to the original post that started this whole discussion, poor old Lambo who asked the original question is still none the wiser about how to fit a 308 to his Disco. :tease:

But on the bright side he now knows if he ever finds out how to fit a 308 that he can with a bit of fiddling get upto 700 hp out of it if he wants to spend the big buckeroos.
I'm sure going from about 200 hp to 700 hp will assist your 4 wheel driving experience immensly. :burnrubber:

As well as that he has also found out that all Rover V8's apart from the trusty real old 3.5 are pretty much utter crap. :wasntme:

Anyway Lambo good luck with sorting something out with repowering your Disco. Have you got any other important questions you need a quick and definitive answer too? :Rolling:

cheers,
Terry

you guys are funny, bagging the stock rover engine for been gutless - comparing it to worked 308's
Apples with apples..... aparently you can also do work to the rover donk !!



you have missed the point...the same point the other pro ''other V8'' posters have said.

you cant spend the same amount of $$$$$$ on the rover V8 to get the same HP and reliability as other mentioned V8's.

take the LJ in my photo and do the same work to a rover V8, now stick it in and see how you go down the quarter. bet its not close to the holdens 1/4mile times.

dont get me wrong i do like the Rv8, ive got a worked 3.9/4.0 in the ute, built by john davis, but its a slug even compaired to my TD5!
john davis wont build a rover V8 for his bushrangers anymore, his words were '' why? when i can build a N/A gen 3 that makes 1000hp on pulp?''
now thats a telling comment from a bloke sernonomous with the mighty rover V8.

cheers phil

[steve_35]

I agree with most of the stuff in the previous posts

but i still think the rover V8 can be made plenty powerful for everyday use fairly cheaply

And if we compare the Rover to the GMH 253 not the 5.0 or 5.7 it is a much better motor

Comparing a 3.5 or 3.9 to big block isn't a fair comparison

If you do the same mods to each motor and used the same car The Rover V8 will win every time
just my opinion

[400HPONGAS]

HardChina , all that guff from triumphroverspares clearly describes BLOWN engines in ultralight vehicles . 25 PSI of boost roughly translates to tripling the amount of power over its Naturally aspirated form (Eddie Tassones 308/383 runs that sort of boost and makes 2000HP). As can been seen from the latest Range rovers and Disco's , the manufactuer is fitting them with 300fwhp NA and 400fwhp Blown ,Also with 350 to 500 ft lbs of Torque . Im glad the OEM has finally dropped the old Rover V8 as it was just a dinosaur . It appears that even the OEM believes that for a decent driving experience , these new levels of engine performance are required to have competitive product along with modern day fuel efficency requirements. So todays rangie has more than twice the power , weighs more , yet returns better economies than anything fitted with the "Rover" V8 in any of its guises .The TDV8 and TDV6 are outstanding Oilers , lucky they share nothing from the old Rover V8 !!!!
PS The new rangie with supercharger is reported by Landrover as 375KW , now thats getting near the old 500HP range isnt it ? Why on Earth would they make these things when the old diehards are quite happy with 150 HP !!!

Thats exactly it but there will always be luddites. The die hards all talk about bottom end where they should have bought a diesel. The new engines will pull for much much longer and probably still have twice the torque of the old Rover V8 at those low revs.

1000 hp naturally aspirated hey! And on PULP.Tell him hes dreaming:D I think he would mean with a a couple of big turbos sitting on the side of it.In the end it all comes down to how much money you want to spend on it.The Gen Motor is a great motor and so is the Rover V8.You just have to remember that the Rover motor has been around for a few more years the the newer Gen motors and are generally running over 200.000km on them.
If you want to run a little more horsepower on the Rover V8 motor then i would recommend a twin turbo set up.I have a single turbo set up on a Rover SD1 and it would put the HSV R8 to shame :D.And with better torque then a 5.7. (If you only saw the look on his face)
It didnt cost me much to do.Dont let people tell you its going to cost you an arm and a leg to do because it doesnt have to.Just do your homework properly and you can have the best of both worlds.

I thought we were comparing the rover engine to a 308 ?
(if you're trying to make me look silly, dont bother i can do that all by myself :p)

I'd certainaly swap out the 3.5 for a gen111 or the latest rangie supercharged beast - as long as it were a real cheap option. Although I have no desire to have a 500hp 1985 county :eek: A 500hp RR sport would be nice... but my little 3.5 powered county would **** all over it off road, so why bother ??

How much power can you really use in an old rangie / disco ??
I know you can use it all on a dyno ;)
maybe for comp's heaps of power would be cool, but on road, bush bashing, dropping the kids off to the footy :confused:



Im glad the OEM has finally dropped the old Rover V8 as it was just a dinosaur .


holden dropped the 308 for the same reasons.. but they did it first :p !

[steve_35]

I think there's one thing we can all agree on

They sound so much better than the other 4x4's its not funny

I sure wouldn't swap it for a cruiser or a pootrol's motor

[TerryO]

Steve please don't add another level of complication by mentioning Pootrols and Crusiers. :bangin:

This arguement is just getting started so saying something that everyone will agree upon will only stuff things up. Bugger me dead it will be the end of the discussion! :eek: Now we can't have that!

Personally I think you are all wrong and your all girlie blouses, a mildly tuned 289 Windsor would smash both the old Rover V8 and the Holdunga boat anchor in all departments and just to add insult to injury its sound even better again when on song. :angel:

By the way, has anyone heard from Lambo lately? ...You know the guy who started this tread!

Sorry i should have know better :)

[RoverP6B]

Must admit that the Ford 289 with twin exhausts does sound pretty good. Better than the 302 and the 351, and better than the Holden boat anchors. The Chevs sound pretty good too. Rover V8s of any capacity sound great with twin exhausts or a nice large single.

Had a look on a Commodore forum...a comment made about the 253....the power of a 6 with the economy of an 8...:p

[PAT303]

A mate of mine has a TRS 4.6 in his disco and it is a very nice thing to drive and was 5K drive in drive out and best yet looks and feels factory stock.There is a reason modded vehicles are worth less than stock,because they are generally troublesome vehicles. Pat

Interesting opinion of a 4.2 Holden and obviously comes from someone who has not owned one. The little 4.2 in my Torana won quite a few drags against 308, 302s, 351s and an assortment of 6's. I would really defy any of you stupid Ford Freaks actually quantify you boat anchor statements. Just look at most marine v8's they are either Holden or Chev. Most Ford Rods have Chev engines and the numerous Holden V8 conversions says they cant be that bad.
The 4.2 could rev significantly harder than the 308 and that is what its appeal was.
What are people comparing when they say power of a 6 with economy of an 8?? You can not compare old technology with new. For that matter how many years was the XR6 turbo actually quicker than Fords boat anchor 4.9 and 5.0 litre v8,s? Why do Fords not sell?

[CraigE]

I agree with most of the stuff in the previous posts

And if we compare the Rover to the GMH 253 not the 5.0 or 5.7 it is a much better motor

If you do the same mods to each motor and used the same car The Rover V8 will win every time
just my opinion

I would have to disagree, I think they are on par. Both fairly reliable and about same on power with the 253 slightly better. I reckon the 253 4.2 in my Torana and HQ was about the same as my 4.2 stroker RRC. The 253 leaks less oil and was easier to get parts for. Do not get me wrong I think they are actually both not bad motors.

[CraigE]

500hp from an old 308 id like to see that i was only ever able to squeeze around 350hp out of them and that cost over $6000 10-15 years ago

A mate (no longer with us) built a 500HP 308 himself around 1986. Built for good power, street drive ability and reliability. In a SS Torana was a very quick car. There was not a lot around that could touch it including a 454 SS Torana I used to drive quite a bit. The engine went from his SS into another around 93. The engine is still running in a VK Commodore from memory and still strong with only minor freshening up over the years (rings, bearings, lifters, cam) to same specs. Total build cost was around $4k back in 86.
Probablly best to compare efi engines to efi engines and NA to NA.
Oh this Torana was also clocked by the police on a lake out of Kalgoorlie at 274kmph twice with a 4spd box and 9" diff. When it was put in the second SS we were out on a run and I was on my GSX Katana 1100 and was ringing that doing 245 kmph and this Torana went by me quick. Ofcourse was on private property.

CraigE wrote,...

Hello Craig,

No probs, no offence taken...I was stiring the pot so to speak. It is true that I have never owned either, and that is a choice that I made. There were problems with the 5.7 Gen III as doing some digging will reveal.

If Holden felt that the 4.2 and 5.0 were such great engines with loads of potential they would have continued their production, but as we know that didn't happen for one reason or another. In unleaded form, both were dismal in their power and torque delivery. I appreciate that many mods could be undertaken just as many mods can be undertaken with a Rover V8.

The Rover V8 was in production from circa 1967 till 2004 and now the block is manufactured under license by Cosworth, so clearly it was and is an outstanding engine.

My 3.5 V8 ran without ever leaving me stranded for 33 years until being retired. By all accounts I could have installed a new camshaft, bearing etc and continued for another 33 years.

It just irks me when people pile criticism on what is without doubt one of the best V8 engines ever made...43 years and counting.

Ron.

Ron, the Rover motor is a good engine, but so it should be being an alloy v8. Really for what it is should be a lot better. The old V8s like Holden and Ford were cast and old technology, but were in production for so long as neither really wanted to tool up for an alternative. Holden looked at many options and purely for economical reasons went the GM 5.7 and variants path. A lot was due to GM only wanting minimal engine variants world wide. Plus they were in a HP battle with Ford. We actually have a 5.7 WK Statesman and it is a good car but I think the VT 5 litre with a few minor mods (air flow and fuel mainly) was far better, had more torque and more economical. It was a tyre shredder for a wagon and impressed a lot of sceptics. Put out 246 odd KW at the rear wheels and I did have the dyno sheets for this. The Statesman only puts out 240KW at the Flywheel.
Sounds like you had a good run out of your Rover and that is part of my point, any motor if looked after and used as intended will last. Most of the Holden engine failures were and are due to cheap HP mods that are not compatable with reliability. It is relatively easy to make HP, just not reliable big HP without $. Stroke out a Rover motor to 5 litres, put on a big carby and see how long it lasts. Have seen plenty of all motors including Rover V8s go bang. I can show you one yard in Perth were a guy has 20 Rover blocks sitting around that have gone to heaven and can not be salvaged. Most of the Holden and Ford blocks get rebuilt for street cars, drags and speedway.
My Grandfather had a HQ wagon with 253 from new in 1974 I think? until died 93 and it never missed a beat, did over 500,00kms and never ever let him down.
Dont get me wrong I loved my RRC 4.2 stroker and miss it greatly.
you mentioned the issue with the first batch of 5.7 litres in the VTs and VXs and these are well known and doccumented but have nothing on the 4.6 Rover issues or even the TD5 issues.

[TerryO]

I would really defy any of you stupid Ford Freaks actually quantify you boat anchor statements. Just look at most marine v8's they are either Holden or Chev.



CraigE you say ...Stupid Ford Freaks!

Thats not being very nice. :( You might have to consider moderating yourself if you keep that kind of behaviour up.

Why quantify my comments about boat anchors your the one telling the story that Holden V8's deserve to be fitted in boats rather then Fords.

I'll go one step further I bet a standard 260 V8 Ford Compost would suck the pin stripes off of a standard 253 Kingswood. And beyond a doubt the Ford still sounds much better!

Great little engine the Windsor was, even the 221 was a better engine overall. [bigwhistle]

Have a nice day. :)

So what do you have to do to fit a GMH 5 litre in Land rover

I don't see the reason for it.What advantage would a cast iron 5ltr have over an alloy 4.6?.Seems to me that there is alot of hassle for not much gain,just a question too,why do you need 500hp in a Land Rover?. Pat

However, others do see the reason for it. :D

[Slunnie]

Yea don't do it, cause I've never tried it:rolleyes:

Downfall is, no adaptor for the auto to transfer case, can mount the 5L infront of the ZF, it'll handle it stock, but if you plan on upping the HP after that, it won't take to well and are big bucks to build tough

They are an easy engine to use in a conversion

I'd suggest 6L 4L80E:twisted:
Did you mean the 6L80E or the 4L80E?

Just googling around. The 6L80E was in the VE Commodores and WM Statesmans with the 6 litre V8's. The 4L80E in the Suburbans as previous said.

[PAT303]

However, others do see the reason for it. :D

Thats what I'm asking.What advantage does an old type cast iron V8 have over an old type alloy V8?,seems like lots of work for 400cc. Pat

[Fish78]

In the words of the Prosche Cayenne ad...

If you have to ask why you need 450BHP to drop the kids off at school your not thinking hard enough..lol

[steve_35]

I can definitely see a big power increase from the stock Rover 3.9 to the stock GMH 308

But It costs about 3000 for the kit from marks adapters
Then you have to start changing major components to strengthen everything

As i said its much easier to modify the motor that's there its cheaper and will keep it factory to the eye

The reason im keen on the rover v8 is im putting one in a 67 Cortina as my next project
There is no other motor that i would fit to this car full stop
Lightest v8 i can afford
Plenty of power
Plenty of perrformance parts
Heaps of poeple that dont mind sharing there knowladge about them
And i have one in my land rover and love it

Parts availability. Cheap performance upgrades. Virtually indestructable (no slipped liners, etc), great looking intake manifold, neater engine.

There are a few advantages... :p

[RoverP6B]

The VB Commodore made from 1978 till 1980 came with 4.2 or 5.0 litre engines, meeting the requirements of the day in terms emissions etc.

A whopping 87kW and 114kW respectively.

VB Commodore Specifications (http://www.uniquecarsandparts.com.au/holden_commodore_VB_technical_specifications.htm)

Cast iron technology is old technology, however strong it may be. I don't dismiss it as an option because of that, rather on the terms of mass and how such an increase will effect the dynamics of the LR into which it is fitted.

You could always just buy a later Range Rover with the Jaguar V8 engine. I recall they were in the order of 500HP, totally modern and not at all agricultural.

Ron.

[PhilipA]

I have sort of changed my mind on this.
I used to be dead against it, but really a 5litre GM is only about the same weight as a (cast iron) Tdi, especially if you put alloy heads and manifold on.
So no one rubbishes Disco tdi's for bring unbalanced etc.

I personally would prefer a Gen111 to either as they are light and I believe in large capacities they are more reliable as they are designed from the outset to be 5.7 litres or so. I have just finished re reading Tuning Rover V8s and all the problems that the 4.0 and 4.6 have.

The big thing is that large GM flywheel not fitting in the ZF bellhousing.
I reckon you could cut and shut a manual gen111 bellhousing and a ZF bellhousing to make a hybrid, but noone yet seems to have done it.

GM fans I assume that a Gen111 does NOT have the 2 positions drilled for the starter motor that a 350 has for large and small flywheels. I have searched and searched with no result.

[big guy]

Back to original question.
You can fit almost any engine, will it comply? That is another question and you will have to check with local requirements.
Simplest from my experience is to keep block and hat that stroked.
Do at least a 4.6 or 4.9L, do the injection system(Haltech or equivalent) and some head work etc.
That way you keep the same engine no, no one will know unless they stripp down the motor or drive it.
There is a huge difference with road manners from a 4L to 4.6, especially in high compression version.
With sufficient funds you can do almost anything the question begs? Why would you? For $8k you get a stroked thumper that will pass engine no inspection and make the car go as it perhaps always should have.

I like going with the KISS principal and its worked for me.

Alternatively, wait till the market section has one where all the work has already been done, they do appear.
Good luck.:)

Any different to the mass increase when fitting a bullbar, driving lights and a winch? Heaps of Landrovers / Range Rovers with those extras added and no complaints about dynamics being effected.

Hello Philip,

Did not the 3.9 have more problems than the 4.6? I seem to recall it did. The 4.0 was by far the worst in terms of cracking, but it all boiled down to radiator hoses bursting and engines overheating. I dare say any engine allowed to experience such will come off second best. That was at least the major contributing factor. Lean fuel maps and excessive operating tempertures for an engine that was never really designed to experience such also contributed no doubt.

Once the Rover block be it a 3.9, 4.0 or 4.6 is top hatted, then the problems are over. The Tempest engines from 1994 till 1999 or so were more prone to experiencing liner problems than the later Thor engines, so it is my understanding.

The casting methods used by Rover were fine for 3.5's but not accurate enough for the motors with bigger bores. The bores that were produced and measured with the most thickness went to the 4.6 and the thinner ones went to the 4.0. This is as I understand it why the 4.0 is more prone to cracking, but all of them are in the same boat.

Hello Slunnie,

Yes I agree. From what I have heard, the new blocks being produced by Cosworth are much better in this regard. No cracking problem....so far..:cool:

In the words of the Prosche Cayenne ad...


If you have to ask why you need 450BHP to drop the kids off at school your not thinking hard enough..lol

Put 450hp into a rangie and the only things you'll drop are the diff centers :D

[PAT303]

I'm with big guy on this one,it's not that there is anything wrong with a holden V8 but after buying all the parts to make it fit and an engine you don't get much bang for your buck.I'd still go a 4.6 and spend the money I would have spent on adapter kits etc top hatting the block and doing a few performance mods and be happy with it.Putting more power through drivetrains not made for it just causes headaches,the brakes aren't good enough for a stock 4.6 for starters. pat

Not so sure about that. V8 Developments report cases of Cosworth blocks having the same cracking issues. This was mentioned earlier this year on the TVR, BritishV8 and RangeRovers.net forums.

The only sure permanent fix is top hatting, but once done the RV8 will go on for years with no problems in this regard. And if you do the right thing with tuning, it can produce some very respectable power to weight figures.

[rovercare]

Did you mean the 6L80E or the 4L80E?

Just googling around. The 6L80E was in the VE Commodores and WM Statesmans with the 6 litre V8's. The 4L80E in the Suburbans as previous said.

4L80E, don't think you'd need 6 ratios....plus the 4L80 adaptor is available to LT230

Advocates of the Rover V8 must remember, just because they did it (i.e fitted 4.6), doesn't mean they have too knock the alternative options, why poo poo something you obviously know **** all about, have never tried?? I love for an answer;)

Rover V8 heads can NOT support large capacites effeciently, so your scrwed from there, the last LS1 GU patrol I wired, has a baby camshaft, valve springs 3" single exhaust and a Mafless tune, it made 260HP on 35" tyres, and will return 15-16L/100, let me see your aftermarket ECUd rover stroker do that on 36's

Why convert? stock engine, with a substantial power incease, an ECU with closed loop, timing control, transmission control and you can plug it in at any holden/efi live/LS1 edit tuner

so an LS1 is the same as a 308 :confused:

the question is - do you think the 308 is a better swap for a propper built 4.6 or 3.9?

Not better, not worse, just different.

No a 308 isn't a worthwhile conversion, but a fuel injected 304 is or better yet a 5.7 or 6.0l;)

I have a rebuilder 308 here, with all adaptions to suit LT95 if you wanna buy it:D

Did not the 3.9 have more problems than the 4.6? I seem to recall it did.

Well not as far as I have heard, even though they have the same structural problems, and it's mainly because of the installation.
RRCs and D1s have an 88C thermostat and a humungous cross flow radiator.
38As had a 95C thermostat in a different position and a smaller radiator set too low. In addition a high percentage overheated due to radiator hoses bursting. I was present when one went once.

Des Hammill in How to Power Tune Rover V8s estimates that 25% of all 3.9 and 4.2 litres crack and 80% of 4.0litre blocks. 4.6 estimate is 15%.
I am a bit sceptical about whether the rebuilders who install the flanged sleeves do it properly. Hammill describes the procedure used by Wildcat and it is quite time consuming, involving sealant at the bottom of the sleeves to ensure no water gets out at the bottom, then a further final press.
3.9s (and 3.5) also have the problem of bearing cap shuffle, and Hammill recommends buying a new 4.6 as the safest option. BUT who is building new 4.6s now? Are they using the top quality blocks or just any block. RPi is now saying that the flanged liners are not a long term answer and that only the new Cotsworth engines are any good.

I would hate to spend 5K on a new 4.6 and have it die from a slipped sleeve.

it would be cool if they redid the 4.6 core patterns to the 3.5 bore spec and just realised that forced induction was the go. ****, they did it with stupid diesels, but not the 3.5. oh well.

A blown / turbo'd 3.5.. :cool:,

4.6 block @ 3.5 bore = no cap problems, no cam wear problems, good oil pump, proven long lasting strong designed block, no probs with slipped liners.

The 3.5 should never have been taken above na 3.5... stupid rover :(

[PhilipA]

They did in 1995 for the British army and ALL suffered from slipped liners because of the way they did it.
BUT yes it would be a good idea.
A cross bolted 3.5 with 2 Subie turbos would go well .
The British motor industry seems to have a talent for snatching defeat from victory, something like our soccer team.

I'm not poo pooing the idea but fitting an LS1 into a disco is more than an engine change isn't it,to make it a reliable converson involves lots of electrics,two stronger diffs with axles,bigger brakes,exhaust,welding and cutting and a engineers certificate not to mention patience and more money than the vehicle will ever be worth.I'm a realist,not a dreamer.

When you think about it logically, how much power does an engine require to drive a LR or RR effectively?

I know some people want 500HP or 1000HP at the wheels which in reality is stupidity gone mad. What ever for???????????

Driving along a freeway in Australia, unless in the N.T, speed is pegged typically at 100kph. To maintain this speed on level road in a normal family sized car requires from memory 40HP or there abouts. So a little bit more in a LR or RR.

Torque is what is really important, much more so that outright HP, so how much is necessary? The standard factory 4.6 produced in the order of 400Nm, and with a different cam such as a high torque edition the torque will come in sooner and improve low and mid range pull.

A 5.7 or 6 litre Chev will deliver more torque, but is it really a benefit? A Range Rover already can go where most would rather not take it, so what will be the advantage? Pushing through sand at a higher speed for example with a full load will only overload the drivetrain resulting in increased wear and reduced longevity...and more cost.

Realist or slack? I'm a doer;), making peoples dreams come true:D

Pretty much the same things required as a tyre upgrade except lots of electronics? 4 relays, 6 fuses and the standard ECU harness I wouldn't say alot

Your very correct, its more than an engine change for a good result, but its the same as upgrading the HP on a rover motor, the rest of the rover bits won't handle large HP and abuse

And yes it can get expensive, if you have to pay someone to do the work, but the poor man pays twice, I've paid twice many times, I had a supercharged 3.9, it was nice and driveable, but nothing on a LS1

I'm not slack,I don't like spending money on cars,thats the reason my defender is still stock after 12 years,VNT,why the original one works,mandrel exhaust,ditto.The original question was fitting a 5.0ltr holden engine,if you read between the lines the bloke wants to know like most people because it's cheap,how many times do you think mechanics are asked what a V6 commy engine would cost to fit to a car,why?because you can get them for scrap money.I can't and don' want my vehicle sitting in my back shed for six months while I spend my free time trying to get it working,a 4.6 is a few days straight swap.

If ever I've learnt something, its that people become biased, they argue why you shouldn't do something, that they've never tried, then use reasons as to why not, because theirs is good enough, again not having tried

Your ****ty rover motor has no timing control, no knock retard, no closed loop, **** ports, slipped liners, cracked blocks etc, they are far from a great thing........yep you can fit aftermarket management, then you loose decent cold start, all the correct idle ups for A/C, roll to stop etc and your fuel economy is CRAP either way:D

Hello rovercare,

I do like my Rover, having been driving it for 25 years, and I have every intention of keeping it forever. One day I would like to buy a LR too, and I might consider replacing the engine, but only with a top hatted 4.6. I see no point really in creating a bitza.

You like what you do and there is nothing wrong in that..for you. Others disagree and there is nothing wrong with that either.

If you ever meet someone who's life dream is a go fast land rover... smack 'em in the head for me, please...

I've watched all the episodes of Fantasy Island and have never seen the little bloke say anything about a 9 sec landy. :)

[PhilipA]

Well I will probably go for a 4.6 next time, but I am still worried about its longevity.
When considering the cost of a 4.6 , you should also add on the very expensive rockers, shafts, head recon etc. Also a 3.9 injection cannot really run a 4.6 without at least a chip at $1000+
So a 4.6 will run to say 4900+ 1000 for heads +1000 for chip. About 7K excluding labour.

A used 4.9 injection (VS VT) should be buyable under 3K and that should include the ECU and wiring. Adaptor to ZF and interfaces for ECU, simulators for GM BCM etc about 2K from Marks.
I would not buy a second hand 4.6 under any circumstances.

[400HPONGAS]

The only problem is that Rover V8 engines are, always were , and still are absolute crap engines by todays standards . Will someone tell me why our latest incarnations from landrover have 500FWHP and better fuel economy ? Hasnt anybody looked under the bonnet of the Latest FORD Falcons ? Seen that engine and Gearbox somewhere else ?

[TerryO]

I'm actually quite amazed at where this whole discussion has gone and the tone of it given that this is Aulro and not some other Japanese orientated 4x4 website where they enjoy bagging Rovers more then anything else.

Sure I have needled a few people by pointing out the irony and or contradictions in a number of thier comments and bringing up about Ford V8's being better then Holdens, that was always going to stir the pot, but it was all meant in fun.

Getting back to the original discussion, some bloke asked 'what it would take to put a Holden V8 in a Rover. I took it he asked this not for any other reason other then to find a cheap way to repower hs aging D1. This discussion has turned into a debate about horsepower and who has the biggest dick.

I brought a Discovery, knowing they are not fast or powerful, but they are really good off road compared to nearly every other 4x4. I spoke with a Landy mechanic before buying and he said to me, 'either your a Land Rover man or your not, meaning either your prepared to accept the fiobles most Land Rovers have and like tinkering and improving, if not buy a vanilla Landcruiser' he said.

I brought a Disco, two actually, and really enjoy them. I now consider myself to be a Land Rover man and I accept the strengths and weaknesses my Disco's have and I like the idea of building up my Disco to my tastes and needs as I can afford it.

Sure I'd like more power and chances are I will at some stage do something about it. But I see no point in putting **** on my Disco's or anyone elses because they don't have 400 hp and aren't very economical and often aren't that reliable. In fact that they are the way they are in some bizarre way actually increases the enjoyment I get from them as it gives me something to look at improving and playing with.

And something even more bizarre I believe, it kind of rubs salt into the Cruiser, Patrol owners that what is considered to be a slow less powerful Rover can be so much better off road then their so thought of far superior 4b's.

Most but not all people who own D1's or D2's own them because they can't afford a new Rover or any other vehicle that is around the same new buy price for that matter. So these are the vehicles we buy and can afford and they have strengths and weaknesses, bt remember they are no less then six plus years old now, some are nearly twenty years old.

I for one accept what they are and appreciate the fact they aren't vanilla motoring. If I want 400 hp and better economy in my 4x4 I will go get a loan for $100,000 plus and buy one and then I'll sit and look at it because I won't want to get it scratched or dirty going off road. And then I will wonder why I have a 4x4 at all.

By the way Ford 289's are still better engines then those unreliable 308's or those crappy slow 253's. ;) And who in their right mind would own a useless slow piece of rubbish Rover engine? Oh that's right ...I would!

Have a nice day.

You haven't heard my opinions on anything that comes standard in Japenese petrol form:D

Mate, 30 years of development will do that to an engine, that is why the LS series of engines are far better than the archaic rover motor, like I've stated, their is nothing wrong with liking your standard rover V8, if it makes you happy, then that's great, but for some people they are not what makes them warm and fuzzy on the inside, they like the idea of having an engine with 10:1 compression at zero deck, knock retard, tuneability etc....all in a factory package

If I was reading this website and was looking to fit an LS1, I'd be scared of by all the wowsers who've never actually had anything to do with engine conversions before....Fortunately, LOTS of people PM me for advice on the subject, as they are to scared to post in any of these threads, you'd be amazed at how many people behind the scenes are interested in things such as an LS1 into a rover...............just I have a big yap and speak my mind:angel:

Anyhow, as stated, if engine conversions aren't for you, then that's fine, but don't knock it, till you've tried it:)

See that's the joy of it, you can have 400HP in your disco you love, for a far lesser figure than 100k

Fair enough your comments about people wanting info on fitting LS1's etc I'm sure is 100% correct, I know they are great engines I've owned a few.

If there was such a thread I'd read it from beginning to end and I bet I'd find it very interesting as well. Who knows such a conversation if based on facts and not a dick measuring competitoin might even convert me.

I'm not really interested in 400 hp in my Disco, I want to use it as a good off road tool and a high perf motor would I'm guessing just break things. I like the idea as I've already stated many times about wanting more ponies but only enough to do what I need plus a couple of extra while keeping it reliable and useable.

I like the idea of a slightly tweaked 4.6 mainly because I like the idea of keeping a Rover a Rover not a hybrid. Just as I wouldn't put a Chev in an old Ford or vice versa. But that is me and I accept my opinion or tastes aren't the same as everyone elses.

That is a shame if people are worried about what someone might say on a website if they have their say or want to ask a question that might not fit into the norm. That is what I have always found great about this website, people hve their say and discussions are usually open and frank and people go out of their way to assist each other.

Anyway thank you for responding to my comments.

TerryO , you know so little about engines its embarrasing ! My point about the Foulcan engine is that the latest Jag engine and Gearbox in the latest Rangies are a direct steal of the Ford engine used here in OZ in the Foulcan. As for a old 289 , you must be joking !!! The 289 dissapeared in 1968 never to rear its ugly head again , around the same time the first 308's were coming out (the manufactures at that time claimed 240fwhp for the 308 and 190fwhp for the 289 !!)

[RoverP6B]

Hello Rovercare,

So an LS1 engine,..what is the standard power and torque for these engines as you would install them into a LR or RR?

How many km have you driven such a vehicle with the engine installed and what was the fuel consumption that it returned both for city and country driving?

What is the cost of the engine and installation? What warranty is provided?

Thanks in advance,
Ron.

Pot stir time

So people keep saying the Rover V8 is crap
Posting pictures of full kit drag cars and claiming massive amounts of power'
Well the only thing i could see on that car that was stock was the oil stain on the floor if there was even one them

Yes the heads make it hard to squeeze power out them but same is said for the iron Gm V8 that's why Yellaterra make good ones cause the stock ones are ****

Fit a 5.0 stroker kit to a Rover V8 Merlin F18 heads and it will kick the crap out of a stock Gm iron 5.0
It costs the same as just buying the conversion kit to fit a 5.0
Marks adapters do the kits for around 3000 same price as a stroker kit and heads

[PAT303]

TerryO , you know so little about engines its embarrasing ! My point about the Foulcan engine is that the latest Jag engine and Gearbox in the latest Rangies are a direct steal of the Ford engine used here in OZ in the Foulcan. As for a old 289 , you must be joking !!! The 289 dissapeared in 1968 never to rear its ugly head again , around the same time the first 308's were coming out (the manufactures at that time claimed 240fwhp for the 308 and 190fwhp for the 289 !!)

I didn't realise you could get a falcon with a supercharged or atmo 4.4 V8 or a 3.6TDV8.I'm behind the times. Pat

[steve_35]

I want one

[CraigE]

The VB Commodore made from 1978 till 1980 came with 4.2 or 5.0 litre engines, meeting the requirements of the day in terms emissions etc.

A whopping 87kW and 114kW respectively.

VB Commodore Specifications (http://www.uniquecarsandparts.com.au/holden_commodore_VB_technical_specifications.htm)

Cast iron technology is old technology, however strong it may be. I don't dismiss it as an option because of that, rather on the terms of mass and how such an increase will effect the dynamics of the LR into which it is fitted.

You could always just buy a later Range Rover with the Jaguar V8 engine. I recall they were in the order of 500HP, totally modern and not at all agricultural.

Ron.
Yep and the KW or HP figures were generally taken at the rear wheels in those day where as now they are taken from the flywheel and there is a fair difference between the 2. There were also a bigger range of diff ratios available and easy to get to alter power and acceleration rates, not available easily for most cars these days.

[CraigE]

So what do you have to do to fit a GMH 5 litre in Land rover

A lot would depend on what you had a vailable and how much work you could do yourself. Personally I would go the 5 litre injected VT engine as parts are still easy to get. Generally I would stick with the rover V8 unless there was terminal damage and I wanted to do something different.
Basically you would need new engine mounts, exhaust, maybe radiator and depending on HP requirements gearbox mods or change. The older Rover auto used to handle a stock 5 litre no problem, not sure about the 5 spd or 4 spd.

No need to be embarrassed, finally it would seem you get it Poogas400, yes I was joking. :lol2:


For your information I've never owned a 289 or any other Ford Windsor V8 for that matter, but I knew some Holden worshipper would bite hard.

I just through the 289 jibe in to see how many would take the bait and start another futile arguement about which engine is better.

I thought anyone who knew anything about old American V8's would have picked up where I was going when I said a 221 (the least powerful V8 since a flathead) was a better overal engine then a 308!

As for new Land Rovers adopting the engines of their then parent company ...well I can't wait until we see the next generation of Rovers powered by Tata Nano engines.

Lets see what you think of the old Rover/ Buick engine then?

Have a nice day ;)

cheers,
Terry

[CraigE]

CraigE you say ...Stupid Ford Freaks!

Thats not being very nice. :( You might have to consider moderating yourself if you keep that kind of behaviour up.

Why quantify my comments about boat anchors your the one telling the story that Holden V8's deserve to be fitted in boats rather then Fords.

I'll go one step further I bet a standard 260 V8 Ford Compost would suck the pin stripes off of a standard 253 Kingswood. And beyond a doubt the Ford still sounds much better!

Great little engine the Windsor was, even the 221 was a better engine overall. [bigwhistle]

Have a nice day. :)

cheers,
Terry
LOL. That was polite, just ask Landy Andy on my real opinion of Ford owners. If you have not gathered I am a Holden man, but can appreciate other cars even Fords.:p The engines were appropriate for their applications and pretty much comparing them is not fair. Yes the 289 was not a bad motor for its time but was obsolete by about 1970. My cousin had a beautiful fastback Mustang with a 289. Same as most cast engines are obsolete these days but do have their uses and are fairly indestructible. Same can not be said for worked alloy or aluminium engines and heads. Most l;ate model engines are disposable units. The old cast engines were designed for ease of maintenance and the ability to be rebuilt over and over, hence low tolerances, which affected performance.

[discowhite]

didnt the rover v8 start life as a GM??

if so they must both suck:twisted:

[rovercare]

Hello Rovercare,

So an LS1 engine,..what is the standard power and torque for these engines as you would install them into a LR or RR?

How many km have you driven such a vehicle with the engine installed and what was the fuel consumption that it returned both for city and country driving?

What is the cost of the engine and installation? What warranty is provided?

Thanks in advance,
Ron.

If you had serious intentions of fitting one to a rover, I'd put the effort in to quote all the appropriate figures;)

[PAT303]

In all seriousness rovercare I'd recon alot of people would be very interested in whats involved the costs and availibility of the componants. Pat

[RoverP6B]

Hello Rovercare,

Yes indeed, time to put your money on the table.

As PAT303 said,..a lot of people would be interested to see the figures, and afterall what is there to hide?

Ron.

Ron.

For me to supply and fit an engineerable LS1 and a custom adaptor utelising a 4L60E you'll need upwards of 10k, $40/hr labour rates and parts at cost +10%, warranty will cover all work involved, not engine and transmission, the price varies vastly depending on what you'd like to utelise in the conversion

[stage one]

Sorry, couldn’t help myself! But, this is getting so far out of hand you guy’s should start a political party! Anything will fit and work if you’re prepared to put in the engineering work, A land rover is just another rolling shell. personally,I'll be putting an old modified, turbo 6 cylinder Perkins in my next project. I’ll work it out myself.

[RoverP6B]

Hello Rovercare,

Do you have fuel consumption figures too for city and country running once installed within a Land / Range Rover please?

Ron.

[400HPONGAS]

Pat303 as Ive built many 308/304 5 litre strokers from 350 to 550HP Ill spec up and cost say a nice mild (400HP/400ft/lbs/4000rpm engine)
First get a VN to VT Block and heads , easily obtained for around $500
355 STROKER hIT ,Made up of NEW CRANK,Rods,Pistons (Flat top 383 chev Hypereutectics Final comp 11:1),Rings ,Bearings,Gaskets , In SCAT,EAGLE,COME ,depending on your savvy $1500 to $2000.
Machining " Bore , DEck plate Hone . Line bore Mains, ARP 2000 mainstuds .Deck block to Zero , fit cam bearings , deck heads to 52 CC Chambers $1200 .
CAm , Solid 222 /220 Backsplit 108 LCS in at 6 degrees advanced .500 Lift . $230 for Cam !!. Pocket port , and Newen valve angle job , Port work $1000, Stainless (std 1.94 inlets) valves .Crower/Iskederian springs locks and lash caps , Solid lifters , Romac Timing gear and grade 3 iwis chain $500 A nice set of YT Platinum roller rockers $1000 . All up , for a No compromise motor , that will easuly do 500HP (with a bigger cam) thats $6000 . Then depending on whether you want to Run EFI or Straight LPG (Dual fuel is a Joke and is not worth the effort) Say anothe $!000 for inlet manifold/throttle body setup . The Bunch of Bananas on a standard EFI 5litre is a Disaster By the time you get the adapter plates/mounts/various changes to Radiators and a Exhaust system , you wont get much change out of $10.000 fitted .
So for $10.000 you cab equal a $200,000 Rangie .with 500HP and do it Naturally asoirated instead of Supercharged . The 355 stroker will eat the Rangie motor even with the Supercharger !!! PS for a extra $1000 id definately use the 383 or even the 396 crank , true torque monsters . ! (Easy 500HP/500Ft/lb/5000 RPM . )
Now when upgrading one of the Rover based engines , please ensure you do actually replace everything with new , and by the way that had better include at least a set of Wildcat heads and welded in Liners !!!
And for those Power nuts , fit a set of Dash=9 alloys (Now thats 50 KG off , jeez only weighs 40KG more than the Rover POS)fully ported with 2.080 inlets and Viola 600HP , dont forget the COME 4 Bolt double register mains

Varies vehicle to vehicle, everything I've played with usually runs 35" tyres, you'd be quite reserved in expecting 15-16L/100 on average, although I've never personally run one long enough myself as I'm to retarded to have anything that's somewhat quicker than my 4BD1T:(

My jag with 300RWHP, cammed mafless tuned LS1 can easily achieve 12's on a combination of town/country driven by people other than me.....it gets 22L/100 when I used to drive it

Stroker Engines, Twin Turbo Rover, a Chysler 360, with 500hp....

After I actually got it, and DROVE the ****ing thing HOME....

I think the 390 Holley, Pacemakers, and Twin Exhaust will do for a while....

Was a handfull just keeping it straight at 90kms, let alone putting in 500hp???

Not sure if you guys have seriouslly Drove 500hp, but that would equate to a HIGH 10 second pass at 120-130mph in a HEAVY 3300-3500lb car??

After inspecting all the Driveshafts, Gearbox, Transfers etc... i would hate to be keeping up with the BREAKAGE costs, and Upkeep of such a BEAST, unless some Serious MONEY was spent to do it Properly the 1st time....

Yep 454 SS Torana high tens (which I drove), 308 SS Torana one I was refering to low to mid tens but I never drove that but did witness the passes and was a passenger on more than one occassion. Strip docket was done at the old Ravenswood Drags (I was not there for this but viewed the docket).
Personally not interested in this sort of power for my SS, just want a good reliable, pokey 8. You are bang on with your FRC analogy though. All things are at a cost. As I have said a lot is only viable if you can do some or all of the work yourself. In most cases it is better to stay factory, but not all, experimentation and creation are good.

[CraigE]

Yep, If you had to buy everything or buy everything new and pay labour it would not be worth while, but there are a lot of people with the gear laying around and the intelligence and know how and this is where it becomes viable and maybe cheaper.

and that is why I went down the path of the 4.6 RR motor. After about 2 years of weighing up the pros and cons I desided that i didnt have the money to go down the path of the LS1 and 4L80E, to many bits to replace to make reliable, to many adaptors and Idont have the facilities to do it myself. BUT if I get the urge to make a competition rig, that is a different story

[Traco]

Who said the RV8 can’t make decent hp? 600 bhp from a normally aspirated 3.5 litre Rover! Not bad for basically an old Buick design from 1959. Sure it cost. About as much as a 600 hp GrpA Commodore or Falcon race engine of almost twice the capacity…..

griff engine 3.5 rover/greyhound 600 bhp (http://www.pistonheads.com/gassing/topic.asp?h=0&f=66&t=833297&nmt=griff%20engine%203.5%20rover/greyhound%20%20600%20bhp)

Rover V8 most technically advanced standard bore 3.5 ltr engine ever. This engine was campaigned by Tim Garlick in a 1972 Mk3 Cortina weighing in at 2,700lbs and achieved a best time/speed of 7.70 @167 mph at Santa Pod raceway. ...

Our SCharged D1 3.9 tow truck often returns 35L/100klms when towing. It's on gas and has 130kw at the wheels. We get used to it because it can tow 3.5t with ease, legally which camrys and x trails can't, all day every day. You can't have it all, I agree with Blitz

Hi Eric!

Actually our LS430 (4.3, 32 valve VVTI V8) gets 12.7 city cycle, and has returned 9.8l/100 from Launceston to home on Midlands highway, and NOT driven like an old person.
Last trip to St Helens and back saw 10.7l/100. Overall average for the vehicles 140,000km according to the trip computer is 12.6l/100
It is a very efficient engine...for an oversized 'camry':p

Glad you stuck that Disco on gas, at least you can run more boost now:twisted:

Hello INter674,

My 4.6 Rover V8 has delivered 9.3 litres/100km on two occassions running from Bathurst to Sydney, 100 to 110kph where speed limits allow. Twin SU carburettors too..:) The engine is in a Rover car with a mass of 1300kg, so somewhat lighter and much more aerodynamic that a LR/RR.

OK maybe for that configuration of weight/aerodynamics/tuning/air temp etc etc, but not in general, for vehicles generally fitted with V8s, and the way they are usually driven/used. Anyhow, let's not start anaother debate on fuel consumption because I know a guy with a diesel Hilux (2.2L I think) that averages 25L/100klms...reason being he thrashes it to keep up with the traffic!!

They're reasonable figures for an old tech engine but its not just lighter weight and aerodynamics which are relevant- lots of extra gears churning heavy oil inside transfer cases/bigger gearboxes/extra diffs makes a huge difference. The rotating mass of bigger wheels/tryes is also significant.

Some of use facts, I wouldn't expect an average of 11's either, that was in an SS ute, not a rover, I'd be expected 15/6's as an average overall for a rover with LS1

Hello INter674,

My 4.6 Rover V8 has delivered 9.3 litres/100km on two occassions running from Bathurst to Sydney, 100 to 110kph where speed limits allow. Twin SU carburettors too..:) The engine is in a Rover car with a mass of 1300kg, so somewhat lighter and much more aerodynamic that a LR/RR.

Yep, our Statesman 5.7 averages around 11litres per 100kms at 115-120kmph. At 100 - 110 can get as low as 10. On long trips of course. Got down to 9.5 once on a trip across Nullabor. Depends on a lot of factors, wind, load, up hill, fuel quality/type. Of course it can do a lot worse when pushed hard.
