J30 ring and pinion into a nismo 2way lsd?

[Big Zee]

ok, what years form the J30 can I use for my nismo 2way lsd into a 89 240sx

I want the 3.92 gearing and its not made anymore :( someone said the J30 had this ring and pinion.

thanks

hey man not trying to jack your thread but why do you want 3.92s? i do not fully understand the benefits of changing gears yet, all understand is that higher gear makes the car accelerate quicker with a lower top speed like 4.10s, and I heard that a lower gear like 3.92 is better for turbo. Is that true? oh and I have a 97 j30 with probably 3.92 gears in it( i tried to test and counted about 3.8) not sure if that helps.

I just want longer gears, im making a track car and the shorter gears help for accell but not top speed and the 3.92's will give me both of best worlds :)

just put the nismo into the J30.
use axles that are for the nismo diff.
enjoy.

Same exact diff, same exact fitment, just swap the rear cover. We've been over this since the internet was born.
