R32 Gtr Rear Diff In Bnr34...

[xanavinismo]

Hi all,

Does anyone know if an R32 GTR rear diff bolts directly into an R34 GT-R?

Ie - not the lsd centre but the actual read diff housing...

Cheers,

Glen

It probably does. They are just R200 housings. The front flange should be the same (both have CV joints there instead of a Uni). The axle flanges should be the same. The front subframe mounts should be in the same location (although I suspect the R34 housng would have larger holes because it would use bushes, where I think R32 housing have small holes just large enough for the bolts because no bushings.) The rear plates are probably different. 2 bolt vs 4 bolt, but rear plates are easily changed.

But keep in mind, just in case you didn't expect it, that you could not swap in an R32 diff and its 4.11 gears without doing the front diff too.

There's also some difference in the ABS senders, have a search for Eric (Pezhead)'s problem. Not sure that it is a big deal though.

Shaft lengths are different too IIRC, ideally you still want a R33 Non VSpec rear, for what you are doing

Okay cheers guys. Sooo hard to find one for sale >,<

So R33 GT-R rear diff should be able to bolt straight in then? Ie - shaft lengths arent different?

The R32 GTR uses bushes at the front of the diff, the bush is the same across the R32, R33 and R34. The rear diff cover on a R32 GTR is 2 bolt not 4 bolt, only the GTS variants run the 4 bolt rear diff cover. With the 2 bolt spacing on the R32 it's the same as the R33 and R34.

I can confirm the R32 and R33 rear half shafts are the same length. Nissan lists the same part number across the R32 - R34 GTR's Left 39601-05U00 Right 39600-05U00.

The only thing you can run into with the R32 diff is the early model ones had 30 spline axle flanges and the later model had 31 spline. Nissan FAST lists the changeover as February 1993. If you are only going to rebuild the stock 2 way mechanical diff or run the nismo GT pro (it comes with new axle flanges) this won't be a problem, if you are going to run the quaife ATB helical LSD you will need the 31 spline axle flanges.

Must be vspec vs non that are different lengths... I couldn't remember what but something is certainly different

Are you trying to do the Mines car mod specifically? If so GTR.co.uk has some good info and people who have done it

Motive Garage R32 GTR R34 6 speed conversion

Opposite way round but worth a view

I have done this Glen, PM me and I will tell you what involved

It's to get rid of the A-LSD and replace it with mechanical LSD from the 32

[R31Nismoid]

Yep, it's fixing up the VSpec woes - A-LSD of fail.
