hello everyone first off i changed the post title but for some reason it didnt change sorry im a stupid newbie i just got into the Nissan world was a honda guy but Nissan just seems the better way to go anyways i purchased a 95 240 and was plaining on doing the S15 swap like every other newbie then i did some research and decided to go with the S14 SR20DET the question is what would be the best for HP gain simple switch the turbo with a S15 or is there a better way? one more thing i know the S15 has a bigger turbo, 6sp tranny and dif injectors but is this any other big difference between the two as far as like internals and such. sorry if this is repeated i did the best i could search but i might not have been good enough

thanks for your help

The S15 SR is the worst to wire up; the differential houses the speed
sensor, so a complete S15 6 speed swap requires the use of the
driveshaft, the diff (helical LSD), and the gauge cluster to read the
speed sensor. Oh, and good luck wiring the gauge cluster up. It's not
fun!
