    I think you need to do your research again, you've at least got the ca and sr final drives wrong. :nod:

    OP Edited. Turns out it wasn't wrong just didn't have enough info. There are different Final drives for Europe and the the rest of the world.

    Keep it coming, i will keep trying to get it as accurate as possible.

    That is some usefull info :) I'm going to change my stock diff to a s14 diff, and now i know that the diff from auto tranny will be the thing i'll be looking for :)
    Anyone knows if the diff from rb25 would fit in s13?

    liner diff will fit s13 with an s13 backplate and halfshafts as the bolt pattern is different on the driveshaft flanges.

    just to add a bit more info....s14 final drive ratio is 3.6:1 (48 ring gear teeth/13 pinion gear teeth) for the manual, and 3.9:1 (47/12) for an auto
