for one thing, get a manual transmission as the auto on that won't work/YOU DON'T WANT IT!
For another thing: Buy the b14 SR20 wiring harness. It's pretty much exactly what you need, then if you have the ECU that came with the motor, you need the EXACT type MAF specific to that motor, or get a b14 SR20 ecu and ship it to JWT to have programmed for a specific MAF and injector combo.
