Skyline rear differential

[ichi-go]

Hi all,

Thinking of changing my 2way as it's too much of a b!tch to drive daily. Just wondering what mods will be required to bolt on the skyline rear differential. I'm talking bout the RB25DET rear diff, not the GTR rear diff as I'm aware you need the complete GTR rear end to bolt the diff in. Anyone can shed some light who has done the conversion?

Never read anything about fitting one to be able to help, I'm afraid

R33 or R34?

I think the R34 has a helical diff and the R33 viscous.

Can't you get a helical S15 unit? Someone might want to trade?

I was thinking the skyline rear diff has better final ratio and could possible benefit from stronger longshaft assuming it needs to go with the diff. I've heard of people swapping them just not done very often.

You'll probably at least need to change the backplate on the R33 diff to the S15 one, and the output shafts on Skylines are generally 5 hole where they bolt to the drive shafts, as opposed to six on the S15.

In the main though, you should be able to get it to fit, but for a no cost option, swap it with someone who has a helical diff as I'm sure someone would snap it up.
