I have a 1988 crx dx and a b18c . I put a b18a into a 1989 crx si about a year ago and it was plug and play. This one needs more though. The engine is a b18c1. It has been bored .020 with eagle crank and rods, J&E 10.5/1 pistons still has stock cams with eldelbrock 4760 intake. It was built to be boosted but I can't afford that right now. If I run it n/a what do I need to do for cams, Throttle body, header and ECU . Also can someone explain the wiring. I'm new at this so be easy on me. Thanks.
