Thread: Up grading Power on Series 3 V8

Love it!

Hi All

Chad that's great

Regards Mark

Another series dragster You've done a good job on that, very similar to another one that was around a wile back. It came to an end sadly.

I now see why you want a series based runabout

Yep

All most killed ME......

But not quite, was an Expensive Mishap...

Not much left of it, Lost the car, Engine, Box Diff, axles and everything.

I will never NOT CHECK, wheel studs again, No matter How Thick they are, they Still Wear Out, obviously....

That's a real shame mate, it was a beautiful and very unique car. I remember seeing it at Eastern Creek a while back. What happened exactly? A wheel came off at high speed?

Also if i remember correctly you had a Defender tow car?

Oh, you are serious.

I am looking for something that Unfortuanately won't be used for 4wding, but more as a Project for cruising, and as a Bit of a ROD type vehicle.

I have posted previously in the Series 3 area about what i plan to do.

I was looking at fitting a 3.9l and Z? auto that is for sale on here from a Series 1 disco...

Is there much of a POWER gain compared to the 3.5 and Manual 4 speed? You're comparing 3.5 twin carby to an injected 3.9

It is going into a LOWERED 109 ute, and will be more of a car used to go to hot rod shows and to Tow back my Landrover drag car, at the track(flat tow). I will not be using to tow a car trailer or anything, and was thinking about removing the front tailshaft, but was advised not too as too much strain on the REAR Diff? Correct, the rear axle half shafts will break. These however can be upgraded. You have a Salisbury which is similar to a Dana60.

I have seen people talk of the 4.6 and also of Stroker motors etc.. on here.

What is physically the same size and best option to go for? All Rover V8's are roughly the same size. The differences are mainly internal.

I trying not to need a Engineers report, but if needed i will have too. You must check, but for a 3.9 and a ZF auto you may be ok.

I don't want anything over the top, just something that sounds good, and will crusie, and be reliable etc... Its all in the exhaust as you probably already know.

I am also planning to run LPG and a Dual plane edlebrack type 4 barrel manifold extractors etc... What size dual exhaust do people run for these engines. Unless you specifically want carbies, this may be a backwards step. You can run LPG with the EFI also.

Whats the best way to use it on the highway etc.. I seen on another thresd talking bout leaving in diff lock etc... High range, centre diff unlocked but its still 4WD.

Any ideas, links, or people with ENGINES for sale, I am after as Much info as possible. Check the markets on here, Ebay and check with Bundalene or Andrew e o here.

As the drags are at least 3 to 6 hours away, depending on track, that will be mainly how I will be driving, on the highway...

Thanks Chad

As its a project i haven't driven it yet (ever) lol...

How do the 3.5 go?

It also has lt 95 gearbox. this is a 4 speed? Yes

I was thinking of the ford idea but after speaking to a Engineer it is a massive cost ($2500) and i really aint that fussed on power, just more sound and cruising. Rover V8's will be a very straight forward swap.

I was trying to keep it fairly simple, thus asking of Land Rover power upgrades that will fit.. 3.5EFI, 3.9EFI are the easiest.

I was going to get the tailshafts resized(shortened) and just keep it 4wd, as if I change it, needs alot more done as its NO LONGER a 4wd in eyes of RTA, and engineer.

I understand It isn't going to be a powerhouse, and i have the RACE car for that, just looking at trying to do what I can without costing me a fortune.

For the amount of KM I will be doing the LPG might not be worthwile?

I was just asking.... mainly about ideas for Upgrades that will almost be a bolt in..

Will the ZF auto and 3.9 be a Bolt in conversion? Generally it is. You will need to do wirings, fixing the cables, shifter, ATF cooler and lines, and the fan etc is set differently so you'll have toredo the shroud, the cooant hoses are different also. The ZF auto is about 1" different in output location compared to the LT95, just wait an see what happens before playing with shafts.

Mounts etc... The one advertised here comes with transfer case and everything etc.... Will it fit up to original diffs etc.. ratios/ I understand I am getting tailshafts modified anyway, but if I did this i would go the LPG route as the disco engine is currently EFI. It will, but your ideal would be a Defender transfer case rather than a Disco or RangeRover one as the high range gearing is different. It will bolt in to your stage 1.

I noticed here people talk of the 4.6 v8 etc..

Does anyone know torque or hp differences with these? ie 3.5 HP? or 3.9 hp? 4.6 hp? You will need to do a search on here or use Google rather than getting people to search for you.

I am not a time waster, or dreamer. I cannot work out how to post pics up here of the DRAG car.

Understand I don't expect to have a race car ofr fast car from this strret one I am talking of, just wondering how much difference there is between the petrol v8s and as I am LAZY, I would prefer an AUTO, but as this will not be a DAily Driver, I have to work out if the COSts will outway the gains, like any project.

Thanks again, input and ideas appreciated.

Just the man to put some light on this subject I think your V8 11a should give some inspiration here

Oh I'm sorry, I had no idea it was yours at the time. I've seen the mishap and amazed anyone walked away
Great to find out you made it.
It's a truly unique bit of gear and I will be keeping an eye out for when you have a run in the future.
