what chassis are u putting the redtop in? s13 or s14?
sr20.hybrids.jp (if that address is wrong ill fix it) they have a how to on the wiring for an s13 motor into s14 i think and s13 is just as easy its just a little harder to wire up the a/c for an s14 but jay whitely is currently on top of things working out how to do it on my buddy's car.
