I own an 89' Civic DX with the D15B2 in it. I am getting this guy to show and convert my car to multi-port fuel injection this weekend. He lacks the CRX Si distributor. Everything else he has. I was wondering I just got fro my brother a D15B7 ECU will it work with the Si intake intake-manifold and wiring harness? And what all is he gonna do to my car this weekend to make this happen?
