What Diffs Will Fit What?

4.363:1

So there is a ratio differance between the R32 gtst (4.363-1) and the gts-4 (4.375-1).this is interesting to me as I've just bought what I thought was a gtr full Diff disc to disc.As I'm dissassembling it I've noticed its a viscus diff in it witch means to me its a gts-4 diff which I bought for the bigger drive shafts (I keep braking my gtst one's )So are the half shafts inter changable between the two ?

cheers Peter

Legend.. I can't comment on the R33 NA GTS4 diff's but the R32 GTS4 diff's are 100% mechanical. Well the one that I saw was and others have also stated they are mechanical.

The J30 diff runs the same pumpkin and 6bolt half shafts as a GTR/GTS4 BUT is viscous and runs a higher diff ratio. Before I bought my current mechanical I bought what was supposed to be a GTR pumpkin and axles which turned out to be a viscous unit. The dodgy jap importer *no names mentioned* sold the bits as a GTR rear end but swapped out the diff center for a cheap J30 viscous unit.

What ratio is yours? Its stamped on the crown wheel.

Hi Cubes

Still pulling it down atm only got it today ,as soon as I get it all apart I'll post up some pic's. I bought it as an 90 gtr diff complete. But the cradle is an R32 one some slight differances in the hicas setup as most parts bolt to top of diff

Cheers Peter .

A good way I test the diff is to get the car on 3 wheels leaving one of the rears up in the air (easily done if you have stiff suspension)

Then apply some torque slowly while turning the wheel, with a mechanical LSD the car should take off, a worn out diff or a vlsd would spin the lifted wheel and you will remain on the same spot.

Is that a good way of doing it guys? correct me if im wrong?
