OK, is there another way to check whether my 1992 SE-R has a LSD transmission? I thought that I read somewhere about a letter in the VIN number.
Also, which would be better off the line, LSD or non-LSD?
All of the Sentra SE-R's came with a VLSD, so you should have one. The only SE-R that did not come with an LSD was the 98 200SX SE-R. There are aftermarket one's avialable, such as the NISMO and the Phantom grip.
