Outer Limits 4x4 Board

Some of you may have seen my members thread with my 2a in it (coils, hilux diffs etc), and I have been thinking about doing a motor conversion down the track (to get rid of the LR gearbox).

The reason I am posting it in general 4x4 is because if I post it in the rover section, I wont get the wider audiece viewing it and offering suggestions.

I have thought about different engines and t-case combinations, and they need to be reasonably short (90" wheel base). I have heard that a lexus v8+auto on a bundera (prado) will bolt together and be about 1700mm in length.

If you have a suggestion, if you can, add the type of gearbox used, and the legth of the combo.

I currently have a Holden 202 efi (about 150hp), adapted to the LR box. I have absolutely no complaints about the engine, but I am worried about the gearbox strength (from what I have heard, they are good to about 120hp). I have also heard the transferboxes are very strong.

Another option for me could be to adapt a trimatic to the LR transfer box.

So, add your suggestions here. It needs to be very cost efective, so dont go on about 1200hp big block chevs .

Also, has anyone converted a trimatic to a LR transferbox? it is my prefferred option at the moment.

an easy way with similar results is to get a 3spd vitara auto and t/case as they are TH180 (trimatics) swap the bellhousing and input shaft (also the front drum spacer) and bolt it up. they are a fairly strong t/case and crawler gears are cheap.

Hmm, could be an option. does anyone have the length of a vitara transfer? the other problem is that I have an offset rear diff (its a hybrid land cruiser and hilux rear), so how hard is it put a sierra transfercase on the back of that so I have dual cases and offset rear. What is the length for that combo?

Cheers

Im currently thinking trimatic to LR transfercase. Then turbo the 202 later on

I would have thought that there would have been more replies than this

A couple of good ones I can think of are
1uz-fe
VH41de
2jzge
1jz-gte
turbo the 202
supercharge the 202
LS1
LT1
TPI 350
3.8 ecotec
3.6 alloytec

A good thing about the toyota motors is that you can make most of them 4wd with the use of a bundy gearbox. Im liking the sound of a lexus v8 ($1000nz) as they are cheap, and I can supercharge it later.

Also, the commy v6's seem to put out good power. This will be in a truck that weighs about 1300kg.

what about a 3rz-fe 2.7 petrol out of a hilux - strong, reliable and can be built to make good figures, guy i know has turboed his, boost to 18psi and its awesome

My old boy is currently doing a 3.8 ecotec converstion to his series 3 long wheel. plenty of power, auto, and apperantly the LR transfer is tough as nails. thats the way i would go. Or mabe a rover v8 and auto combination.

how is he adapting the auto to the transfercase?

Cheers

he's a fitter machinist, so he's just making an adaptor.
