how hard is it going to be to swap my 97 200sx se to a SR20DE from a 96 G20?
biggests question is the wiring harness. does any one know were to get a new one?

If you want a new wiring harness you can always get one from the dealer but I wouldn't recommend that because it will cost you an arm and a leg...possibly the other arm as well. I would try either a junk yard or look in the classified section on the forum for a part out and get one that way. You can always find someone selling a wiring harness here on the forum.

thanks, was conserned about getting used cause i would hate a faulty wire to keep me from starting after all the work! but my budget is very limited, so used it is.
would SR16 pistons in the SR20DE and shaveing the head< would that be to much compression?
