What parts can I reuse and what do I need to get? Im planning on boosting too but I need to know if my stock ECU will work with that engine. Right now I have the d15b7 and want to change over to the B18a1. I know i will need harness, tranny, and mounts. Just need to know if my stock ECU will work or will I have to replace to the 90-93 Integra LS.
