Source: factory service manuals, verified with JDM differentials. My S14 5spd 3rd is long af, gets me to 80-90 ish.

So you're telling me, if I buy a JDM S14 SR20DET differential, it will have a 3.69 gear ratio?

Would it be possible to swap that ring gear into an S13 diff?

Yes, ring gear & pinion swaps are pretty common on R200 diffs. You can also use the whole pumpkin and just swap the rear cover to use it in an S13.

Good to know. I?ve got a Kaaz 2 way in mine currently that I don?t want to lose. Just want better gearing for highway cruising
