Thread: Holden v6 into Defender 110 ute

If you were to look up a power/torque curves for say a ALLOYTEC 3.6 190 V6 and any Variant of the rover 3.9 you will find that at no point does the Rover engine come anywhere near the the holden engine in both TORQUE or Horsepower.
I Suppose its the silent shaft and Roller cam ,the 2 less cylinders and the smaller .3 liter capacity really didnt count for much !!!Lets not even go near the latest SIDI incarnation and compare that with a Rover V8.
Why is it that all these wives tales say its allright to have a Rover V8 that makes bugger all useful torque/Horsepower but you cant replace it with something (V6 alloytec) that delivers more torque , is twice as economical,across its entire Rev range .
Rovercares probably right ,dollar for dollar perhaps a ALCOA (LS1)special would be better
Rovercare ,you ever heard of C.O.M.E. racing , look them up in Melbourne and have a yarn about his 4.2 strokers ,say hello to Sam for me !!!

I still say they are noisy, unrefined, sound like crap and are useless as a defender powerplant. (not alloytec, i'm talking about early VN to VR etc) Say what you want but thats my opinion.

Rover V8's aren't all that noisy and harsh where did THAT come from???

Just my 1.5c if you don't like it then, well, tough!

Well folks it seems that once again i have opened a can of worms Unfortunatly not as many replys as my Browns gas post. Thanks for the input and please remember. that opinions are like arseholes, everyone has one. I dont think personal attacks are in the spirit of the forum.
so lets all have a laugh and chill out.

No worries Bazzle, thats why I use heaps of these; '', and these; '' in my posts as it shows I am NOT ''

(See, theres another...)

I think a v6 holden motor would work well if it went into a SWB series or something smaller and lighter, i have looked at this option with my mate and his S3, as for economy i had a few earlier series 1 VN's and found they were the best of the lot compared to the later ones i had, better on fuel, more power, much better torque, these were before holden toned them down a little for the series 2 through to VR before the ecotec, i have had atleast one of them all. I used to get 7-800km out of a tank in a fully loaded VN wagon on the freeway, compare that to the 5-600km from the same ammount of juice in my VS series 2 sedan on the exact same run.

funny thing about the rover v8 and holden v6 is there history together back in to early days all evolving from the same motor, and i have been told a holden v6 timing cover actually fits a rover v8, i am yet to try but i was looking at this option for my comp truck running a delco computer on a rover v8.

The only V6 for a Defender should be a TDV6, regardless of manufacturer.

Ditto a V8.

Well, the engine must have had something going for it. It was from the same engine family as the Buick/Rover V8. The V6 was first made in 1961 and continued until 2008. 25 million of them were produced in almost countless capacities and ratings. The 1989 turbocharged option was advertised at 276 hp but was known to be narly 300. It is said to be only 35 kgs heavier in cast iron than the aluminum V8. The late Series supercharged versions were real good goers. I don't have torque and horsepower graphs and it would be an interesting exercise to compare these, the V6 with the Rover V8.

Incidentally, the engine made Ward's yearly "Ten Best Engines" list several times.

Have a look a [ame="http://en.wikipedia.org/wiki/Buick_V6_engine"]Buick V6 engine - Wikipedia, the free encyclopedia[/ame]

my 2 cents worth.
I also like to convert to buick/holden V6.the holden black 6 is also similar technoligy.the engine makes diesel like tourque at 1800RPM.
or can scream to 6500.

reasons not to.
cost of convertion and getting the engine up to a spec to suit the rover and the possible fuel cost to run it.
the GM V8 will have lots more power but a lots more cost.
dont know if it will fit as it was not made to be easy to convert but the falcon 4.0 is cheeper to service for the horse power.

reasons to convert.
similar engineering to the rover engine-from the same family with similar life time improvements.makes better noises than diesel.

opinion based on experience.
many versions of the buick V6 family-a P76 3.3 was built in australia using alloy block.I wanted a 3.0 version of the BOP block or the first non balance shaft even fire FWD block.many years ago i was going to fit an early import turbo with a TH350 to a P76 or HZ.

I had the experience of refreshing VN-VR engine at 1 per day under new car warranty due to poor build quality not design.oil leaks,coolant issues,cam shaf/balance shaft bearing failure and valve spring and guide issuesIf you had some of the issues you could bet the rest are not far away.
as for fuel consumption the ECU is brilliant but is not designed for economy but our stupid emision testinga rechip turns these into a usable engine.

when testing due to customer complaints I found a consumption range from 7Km/L to 13Km/L tank averages.so to say all these are heavy on fuel is incorrect.to run LPG you have to spend to get the engine to suit as it wasnt originally designed like the ford to run on gas..

like the holden red/black 6 it will suit any aplication if the right tuning and trim is used,there are untold versions of the engine with different sumps and timing case and accesories drive including the fan drien off the belt.

Ive driven comodore steched ambulances and loaded these would be much heavier than a 110 and they are V6 not V8-but the issue is when i load the 110
and then tow a trailer the petrol bill will be atronomical---or similar to my 3.5 auto disco.

the nissan patrol 3.0 is a good match in the SWB [not sold in australia] and the EFI helps with fuel economy in the LWB compared to the original carby.i often wondered how a RB20E/RB20ET would go in the patrol--in my skyline the RB20E has to be driven near the red line and gets 10% better fuel economy than the RB30E if not pushed.
with the engine running at 6400 RPM the car can be driven in first gear.and the gearting will give you some usable tourque that the engine doesnt have.

If only a good indian owned car company made a 4X4 freindly 4 liter 6 diesel.

I never owned a car with one but have hired several V6 Commodores with the 3800 engine. I found them to be incredibly economical for a big car, 30+ mpg in highway use. My 4.0 litre Falcon ute does around 23-24 mpg unladen and down to 18-19 laden.

I found that at peak production GM were making 7,000 of these engines per day.
