-wouldnt a front diff and a rb25 single turbo give it away faily easy ?

I don't know how you'd spot the front diff on the road seeing as its nestled nicely in the oil sum under the engine.

Things to look for would be 4 wheels spinning when taking off and the torque split in the cluster. R33 GTS4's are all N/A and R32 GTS4's were all turbo. I guess to a certain extent if you check out the wear on the wheels of a GTS4 it should be more evenly worn (theoretically that is, ATTESA however isn't fulltime AWD though) also compared to a GTSt, GTS4's tend not to oversteer as much.

oh you mean out on the street driving , not inspection. as in mock ups etc !

i could be a smarty and say not 4 wheels spinning on take off but a combo of 2 rear and 1 front alternating but as you can see i didnt even get the engine right ... :) so i will shut up and say thanks.... i leaned something

If you destroy a motor in a GTS-4, do you have to replace it with another motor from a GTS-4?

its easier and cheaper to... noone has a use for AWD RB20DET's :P as they only fit AWD R32's, A31's and C33's. If its just a damaged head you can replace it with a GTSt head. I think the block might need modification to fit. Oil sump and front diff need to be swapped for sure, or you could use a GTR one (grab one off someone who's putting an RB26DETT into a RWD car for cheap).

I believe you just have to pull the 4WD fuse out on the R32s.

or wire up a switch to the fuse and have a "slide beyotch/grip beyotch" toggle switch in the cabin :P

So you reckon GTS-4 motors are cheaper than normal RB20's?

should be. I mean, if you had a R32 GTS4 wreck and no one wanted to buy the engine, you'd sell it cheaper so someone took it right? Cars that AWD RB20DE's feature in, in general are rustheaps (as most of them were used in snowy areas in japan... hence the need for AWD) so its not like there's any shortage of spare engines.

And if you can't find an RB20DET, then put an RB26DETT in, or an RB25DET out of a stagea (which is pretty tricky, but doable).

Is it easy to turn the front wheels off?

You can also just flick the ingition off and on while rolling (faster than 5km or so). disable the ABS and 4wd (same as fuse)

Then its the same as a front heavy gtst...

Don't get me wrong... its not easy, an RB26DETT swap is easier I reckon.
RB25DET simply bolts straight in. And everything mechanical connects up. At least you don't need a new exhaust and intake setup.

Either engine, you need to re-loom and re-ECU it.

    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
    • I'm interested,do you still have it?
