Considering he is using a GU patrol transfer case a DIY kit with an adapter for that wouldn't help much...... why not a 80 series tcase anyway.... is the patrol one that much stronger??

Yes the Patrol transfer case is stronger but at the moment an adaptor for the Toyota t/case is not available. They will be available in the future, possibly by the end of the year.
How does the 60-series split-case match up against the Patrol one? They seem to work well behind the 4BT swaps I've seen.

I wouldn't have a clue Dave, a few guys I have spoken to from the offroad racing scene here in Oz have all said the Patrol T/case is the go but I guess it all depends on what you want to do with the truck. In my case the Toyota case probably might be alright but I can't wait until the adaptor is designed and machined.

They have been running the 60 series split case behind a 6BT for years.
They are pretty stout cases.

a stock 6bt, like most of the swaps is quite different from a full on Dmax engine.... most likely the Dmax is pumping out double the tq and hp.
What do the patrol T-cases go for used in Oz?

Oh that's right
I forgot this was a tuned up Dmax.
Well if a patrol case can handle it then I say go for it.
They must have some crazy internals.

My concern is even if the l/c tcase holds up to the Duramax, the axles will not. AAM 11.5 is what the Duramax trucks run. I am by no means an expert on axles but i dont think anyone has built a land cruiser rear end stronger than an AAM 11.5.
It would not be the ideal engine for the type of wheeling that is common over here (although getting more common over there too).
I once wheeled with some guys from Oz and they were amazed that the trails we did and how long it could take to get through them. They are more of an overlanding/wheeling mix where over here we have much harder trails like (moab/rubicon) that would but the axles into bad snapping situations.
I think for lighter wheeling and some longs it would hold up fine.

Ah, I forgot you were running an Allison tranny. Yeah, there probably aren't any adapters to mate that to the split-case.

not all but that's right .. I don't think they will push that rear into any really super grip situation .. or Outback Challenge ..

I can get a GU Patrol t/case for around AUD$400

There is an 80 series comp truck over here with the standard diff, only running an air locker and solid pinion spacer all behind a 502 BB (1000Hp, 950Tq), he may be running CrMo axles but the is handling it.

Engine and Trans are finally in my possession. Spoke to an engineer about the correct design and attachment of engine brackets to the chassis rails.
Bracket material can only be a maximum of 50% thicker than that of the chassis rails with attachment to the top, side and bottom to counteract the forces induced by the weight of the engine (both static and dynamic).
Trans is rebuilt with a stage 4 kit and is good for about 600Hp.

Awesome build!
I was wondering if I could ask a favour.... are you able to take some measurements of the engine?? width across, depth, height etc??
Thanks

No probs, try get them up tomorrow for you
Awesome Build Mate...
You may have already side it but what Allison trans is that? 6 speed auto.... if so drool.....
Thanks!

Yep, 6 speed Allison with a stage 4 kit built by Mike L. at Inglewood Transmissions in Fullerton, CA.

Approximate measurement of the engine are
Length = 700mm from front of crank pulley to back of heads (add 100mm for Turbo exhaust inlet pipes)
Width = 700mm from outer edge of heads (add approx 100mm for fuel filter that hangs on the LHS of the engine)
Height = 800mm from bottom of sump to top of accessories. NOTE: the bottom half of the sump will be removed and a new reverse hump pan will be fitted to clear the front diff.
