Okay. I have a 1990 CRX DX that has a D15b2. When I got it, I found that the rings were shot and it had some burnt valves. So, I got ahold of a D15b VTEC. No ecu or transmission, just the short block. My question is, what more do I need to swap the VTEC D15b with the D15b2? The b2 is DPFI and the D15b is MPFI. So my question is, what kind of ECU and harness should I look for? Is my transmission going to fit correctly? Will my engine mount the same as the old motor? What kind of wiring do I need to do with a new ecu and harness? Any suggestion on where I can get those? I've never done a REAL Honda swap before and I need some help If any one could help me, I would sure appreciate it!
