Well putting a s13 motor into a s14 is going to be a nightmare, because it was a motor that was not intended for that car. not mostly the mounts and stuff but mostly the wiring, an s13 motor into a s13 with an UNCUT manual wiring harness is all plug and play for the most part...what i would do is spend the xtra cash and get the s14 or s15 motor. More HP anyways...
