Hi Ben,

I Have put a gtr diff in my 33 gtst, but I just used the GTR housing and swapped the input flange and lopped of the mount for the hydraulic hicas. you need the gtr hubs as the spline is different and of a larger diameter but I assume you have these as part of your "etc., etc.". For using the gtst housing, just check as I can't remember whether the bolt diameter and PCD is the same on the ring gear. If it is you can just bolt your centre into the ring gear and reinstall. While you have the diff out you may aswell change your seals and if your really keen your bearings too. I just put new seals in the gtr housing. You will need to use the GTR output flanges (6 bolt) I will also assume you have these, if you dont, you need to get them. Changing the crap around with the brakes so you can install the gtr hubs is a pain and it would have been easier to change to fork bottom rear struts but this would have slightly changes the geometry at the rear and I was advised against this. You pretty much need to pull the whole lot appart and mix and match till everything is back together. There is a piece which the drum in disk springs hook onto which is a separate part on the ally gtr hub carriers, on the cast iron gtst ones it is part of the casting. There are four bolts to pull the hubs out of the hub carrier on the gtst and four bolts plus the large one for the above mentioned "spring mounting lug"(I just made that name up as it sounded good.) on the GTR hub carriers. You will see what I mean when you get into it. Just realised that you have a r33 gtr rear end and I'm not sure of the differences. I used a r32 one. I'm not going to delete all this stuff I typed cause it may help anyway. If you have the Brembo rear brakes with this rear end you have, I assume you will be swapping that all over anyway so you will need to pull the brakes all apart anyway.

Anything else I can help with though, let me know. I know I struggled to find info when I did it.
