After breaking a driveshaft at the last project d day iv gone standard r32 GTR rear end. They are a mechanical 1.5 way from factory so this will have to do until i can hopefuly find a cheap 2way in Japan.
Heres the pics and basic instructions on what to do!
Basically strip your current setup back to bare s13 knucles. Make sure the stock knuckle is clean and where the hub locates is smooth, clean and free of rust and grime
Bolt the GTR hubs to your stock knuckle. They have 4 bolts as seen that go in from the back of the hub. Use a bit of bearing grease on the splines to help get the drive shafts in and spin freely.
You can see the difference in thickness of the GTR actual shaft (left) as well as the hub end of the spline. The drive shafts are also threaded where they join the diff removing the original nut and bolt configuration. They are still 6 bolt but everything is much thicker.
This is a stock r32 GTR diff as it came out of the sub frame
The stock gtr tailshaft connects to this billet machined flange. This will need to be removed and swaped for your stock r200 flange to keep your existing tailshaft. The nut will undo pretty easily but the flange will need to be tapped out with a hammer.
The next step is to remove the back aluminium finned cover plate and swap it with the one off your R200 diff. This will allow it to bolt into your stock s13 subframe.
The gtr uses a total of 4 bolts rubber bushed allowing the diff to move. S13's are solid mounted in the cradel using 6 bolts as seen above. The front bushings on the Gtr diff will need to be packed down above the diff with washers as well as bellow. Alternativly you can Make or purchase alloy solid bushes, which is what il be doing.

The gap between the subframe and the diff mount will need to be packed out with washers and a longer bolt used with you plan to keep the factory rubber bush setup
Fuel line bash plate is starting to look a little worse for ware but is definatly doing the job its ment to
