v8 + auto options?

Post by Ferwoaza »

Just doing some learning :)

What would be a good V8 engine, autogearbox and xfer case option to put into a fairly short wheelbase vehicle? Low gearing options would be ideal as well. Currently thinking a Rover 3.5L + autobox + toy xfercase would be an ideal combo, but unsure if this is possible, and what auto you would need..

Trying to work out possible combos, costs, adapters required..

why the obsession with v8s. it seems every second person is asking about how to fit a v8 into something. Why not a V6 or a 4 with all the available gearing options a powerful and heavy V8 seems to be overkill. Surely by going with a less powerful engine and low gearing breakages will be fewer and costs will be kept down.

Don't get me wrong I love a V8 as much as the next man I have a VG coupe with a V8 and love it but in the application of a low geared rockcrawler or general 4wd I don't see the need :)

Well...

I've never had a high powered vehicle, want one, so putting in a V8 is a good idea to me :D

I'm not looking at a big V8, the rover 3.5l sounds like a great compromise between size/power etc. Price is also an issue, the engines seem to be going for a relatively good price.

I've heard not so good things about dunnydore engines which is why I shy away abit from their 6's and 8's.

I don't like the tractor sound of lux engines :D ;)

What about a 253 or 308 with a Turbo 350 or 400 ?

Cheap, old school technology for ease of use / repair / replacement :cool:

Not sure about weight or how long this combo will be in a SWB.

Nah, not the Feroza...although...that would be interesting!!

I get paid out from my current job in a few weeks, looking at building a new rig. Contemplating putting a v8 into a Daihatsu Rocky with hilux running gear, just working out strenghts, ratio's, costs etc....feasability study :)

Know a V8 can fit, theres a Rocky in NZ with a v8 in it. I want shorter wheelbase than a hilux...and a uteback rocky looks pretty good :)

I'm not denying you can't go past the sound of a V8. I love the sound of a big block 440 or a Cadillac 500 mmm noisy!

rover V8's can be carried around easily by 2 guys... :D
i think they weigh around 315 pounds or 140 kg's which is not heavy IMHO
there are 2 manuals and 2 auto's which will fit behind it
a 4 or 5 speed manual or a 3 or 4 speed auto
the 4 speed manual LT77 has it's own intergrated t/case
while the other 3 gearboxes all had the LT230 transfer case
low range reduction gears for the LT230 are available from maxidrive

Murray for a comparison the Feroza HDE weighs 95kg, so 140kg is pretty good for a V8.

As can be seen 3.9 Rover is f***ing light. Also 4.4 leyland is basically the same but getting rare (plus bigger bores= less metal so lighter). Alloy Rover blocks are good, 3.9's are even better but reliabilty of any LUCAS EFI has always been an issue- never think about putting the original EFI in it.

Twin 2" SU's are good too if you can find someone who can tune them or kjnow how yourself - if you've done proper mototbike tuning it's easy.


Yeah other options like SR20s and that exist but they wont match the low end grunt or idle speed no matter how you tune them or turbo them.

The feroza is gonna be a squeeze though for any implant especially a V8 and being a ULP model you can't go backwards so the motor would probably need to be a 3.9 Rangie engine for Major expense.

You already have HEAPS more power than the zuki boys so maybe turboing your own is a better option, or a supercharger of a Yota 4AGZE or 1GGZE?

Have you considered something like a 2.6 astron motor from a sigma? With the auot and say a MQ LWB divorced transfer. Just an idea.

i have a feeling that may not have been complete. As I remember buying one thinking cool, that is mega light. They ended up being heavier than I thought. Probably closer to 250kilograms. AND i dont think 2 people could lift one complete. Thats from fan to bellhousing. Filter to sump, including extractors, and probably a pallet?

an hour later but yeah at least you agree. I think a short motor MIGHT weigh 140, but i doubt it

What about a Lexus 4.0L Quad Cam V8. There pretty light and not too expensive. Have seen em for $1500 + computer.

I know someone who put one in a celica mustang back, with TWIN TURBOS. The thing did 8's or 9's at eastern creek.

I also know someone thinking of putting one in a SWB serria.

You'd want to get one with a computer, otherwise you're looking at custom wiring looms, buying an aftermarket computer, getting someone to program it, plus dyno time..... $$$$$.... And then you'll be lucky if it runs as smoothly as with the factory computer- especially things like cold start mixtures which take a lot of experimenting to get right.

I wouldn't recommend this route unless you've got a lot of pals in the auto industry who owe you favours!
