Comparing the s14 SR20DET and s15 SR20DET, which one is more reliable? and i have heard that the 6spd for the S15 SR is not that good, is that true? whats bad about it? I m plannig to swap it into a 95+ 240.

Thx

from what i hear for the S15 you need the rear diff aswell, it has the speed sensor. and yea i also hear teh 6spd is no good.

yes, the 6 speed is hard to maintain and you do need a read diff and the speed sensor as well…not an easy job by any means
