Have a Nice Day? Which rear-diff?

Hi all,

I have a 2002 JDM WRX-NB motor which comes w/ a 5spd tranny but it's missing a rear diff. I'm wondering which rear diff I could mate with it? The ratio is as followings...

1st - 3.166
2nd - 1.882
3rd - 1.296
4th - 0.972
5th - 0.738
R - 3.333

Final - 4.444

Could I just use any Subaru rear diff which comes with a 4.444 ratio?

Thanks
Barry

yeah. An RS diff would work. Try and get one with LSD also many ver3/4/5/6 STi R160 diffs were 4.44

Thanks for the reply. But I thought the RS diff is 4.111? I'm trying to get one that's easy to find locally. Anyone have a list of diffs I could use, like off a Legacy, RS, etc?

Hey LAT B,

I have done that same mod.
I used a Forester rear diff to mate with a JDM 4.44 tranny.

Most 2.5L automatic subarus since 1998, including Impreza RS, Legacy GT, Outbacks and Foresters. (maybe even before)

Easy to come by. I bought a 4.44 LSD from an 01 Legacy GT. I am putting a JDM 4.44 auto in my Legacy Turbo.
