Get an FJ20E diff if you want to get the car working through the gearbox quicker

Hm... I checked the manual, and the s13 diff is 3,916, whereas the fj is 4,111 (from the topic about ca boxes). So in conclusion i should be geting shorter gear ratios... Not bad, i hope.

Hm... I have the s13 gearbox (its not in the car yet), but diff the will be staying the same, from my s12, if everything fits ofcourse. (im not sure what exactly is crown wheel and pinion, but from what i found realy fast in google, these gears ar in the diff, so im hoping i wont need to change them)

Yeah they're in the diff.

You need to compare the gearbox ratios not the diff ratios
