ALL nissan r31 silhouette and gts1 & gts2 (australian models SVD) had borgwarner live axle lsd's from the factory.
series 1&2 silo's (manuals) and gts1's (all were manual) had 3.7:1 all series 3 silo's, all autos and all gts2's were 3.9:1.as they were sold new in Australia.

many of the cars had diff problems (noise) under warranty and they were replaced with the later 3.9:1 units.

the other models could also be optioned with an lsd when purchased new.

jap import r31's have IRS with a long nose r200.

I hope this info is helpful.
