What type of Diff?

Hello all, I was wondering what type of rear differental do we have on a 91 NA coupe manual? Meaning is it a LSD type or what?

It should be an open diff... not LSD. I believe LSD's are on the TT only.

Yes. All Z32 R230 LSD's were viscous. That's why the NA 4.08:1 R230 diff is a popular swap into TT's. Shorter gears mean faster spool up! WooHoo!

The Turbo only LSD was the Z31 from '87.5 to '89 model years and it was also a clutch type except the '88 "Shiro" or SS special edition which was a viscous R200. All non-SS Turbo's were clutch type R200's.
