I'm gonna be doing a mini me swap on my 90 crx si soon. I am gonna be converting to obd1 and running a p28 ecu. I am getting a z6 head, intake mani, fuel rail, and fuel injectors. I still need a wiring conversion harness (might just make my own), all the gaskets, new oxygen sensor, and distributor. Do I need to replace any other sensors? Also I am thinking about getting an aftermarket header (not sure which one yet), and should I change the throttle body too because I know the one from my a6 has a different bore size then the z6 intake mani. Any help or suggestions are apprecieated.
