can the guts of the viscious lsd be put into the case of a r 180?

Possibly? I dont think anyone has tried it an posted their findings that i'm aware of.

Have a read of this, it discusses the same thing:

You would still need to have the axles to match.

Where did you source a viscous LSD out of an R180 differential?

my friend has a viscious lsd for a 300zx and asked if i wanted it, but i don't know how much is involved in the conversion.

Then you have an R200 LSD. Valuable thing.

S13 Slivia/180SX had them I believe.

If it is a 87,88 or 89, yes it is an R200. If it is Viscous then only an 88 SS and again you have to have the axles if it is an 88 VLSD. The axles are incredibly difficult to source.

It could be a VLSD from an 90-96 which aren't as valuable.
