my brother in law has a silhouette R31 skyline at his work for parts. im wondering if they are LSD? and same diff centres as the 28spline vl lsd? also are they 3.45 ratio like vl's? thanks

pretty sure sil's are all lsd. auto's were 3.9s and manuals 3.7's i believe centre's are should be the same

correct skylines run borgwarner 28 spline, lsd for sure in silo diff housing different of course

Above is all correct, it will fit in a VLT or VL V8 diff (not n.a) Is it manual or auto? Let us know what ratio it is!

28 spline skyline center into a vl N.A 25 spline?

thanks for your help, havent seen the car yet dont know what tranny it has, definitely be changing from 3.9 to lower, car revs high enough on freeways

Yes it will fit in a na housing, obviously your axles won't fit been 25 spline and centre is 28 spline

Yes i ofcourse know that, all bw78. It will fit into a na housing yes, theyre the same. But it wont fit into a n.a vl 'diff', interms of the 25 spline axles - thats what i meant.
