i'd look at the usdm p72, the jdm p72 that came with my friends motor was horrible. even my stock p72 made it run better. i heard about that online but dismissed it, but when we tried it out, the usdm counterpart really did make it run better.

i'd also put on a skunk2 manifold before i put the motor in, score a usdm harnass and obd2 to obd1 jumper.
