Thread: five litre conversion ??

And if your chasing a low stall converter for the 700, I have one that's barely been used sitting in my shed.

This could become an interesting build thread.

Wasn't there a RRC that was sold with a Holden V8 in it? Was it a Schuller or a Brock?
What did they do?

Schuler became overfinch. They had 5 litre and 350ci conversions.

I can appreciated some questions about all wheel drives versus rear wheel drive.When you have a big motor with heaps of torque it wheels spins very easily on the front tyres. Secondly the LT 230 centre diff with the cross shafts and spiders are a weak point with lubrication issues on the shafts. With a simple mod you can have rear wheel drive and reduce the risk of blowing up the centre diff and the front end.
Roger, it still locks in 4wd the same way. Talking from experience it drives better and doesn't pull left or right under heavy acceleration.
I'm not sure if Bacicat or Dougal have big engines in there Rangies but I've tried a few combo's and this works for me.
My Combo, 383 chev, roller cam aluminium heads, M122 Magna charger supercharger 10psi, turbo 700, lt 230 & defender 110 rear diff.

Don't over complicate it, get the transmission adapted to the LT230 and run it as it was intended.

Hi Bacicat have you tried rear wheel drive? Have you ever blown a rear diff and drove on the front diff in an rangie? I have to disagree with you I reckon the old rangie drives much better from the rear.

Installing the defender 110 rear diff.
It bolts straight up. Your wheels will fit (same pattern) and the diff is the same ratio. By memory the only thing was shortening the tailshaft and swapping over the spring base plates on the diff housing.

I've done rwd while sorting out prop shaft uni joints. I much prefer full time 4wd.
Better traction, especially noticeable in damp tarmac where you can't use locked 4wd.
Better handling as the front end tries to squat under power instead of lifting.

Yes one of mine spins front wheels occasionally. But when it does that it is still providing more grip and drive than a 2wd can. A torsen centre diff would put a stop to that.

My test was done with 33" tyres and big torque cast iron engine. Maybe a stock 3.5 V8 with stock wheels probably behave differently. One thing to consider dougal, there's less risk of braking stuff transfering the drive to the rear with big torque.

Going 2WD in that scenario means you really have to have a bullet proof back axle and driveshaft. The centre diff is easily strengthened. I have driven both my own RRC with just the back shaft in - didn't like it, and I've driven a 2 door RRC with a 350 Chev in it - in 4WD with 33's on it - it was fine - the castor correction had been done properly and it handled well.

I still don't see a need to make them 2WD - if you want a 2WD 4x4, just buy a Toyota....
