Well I just bought a d16y8 from a 00 civic EX. This will be replacing my crappy d16y5 which came in my civic HX. The question I have a few questions for everyone. #1. Will my HX wiring harness work for the d16y8? #2. I will need to buy the p2p ecu, correct? #3. Is there anything else I am forgeting? Lastly, I also bought a turbo kit, apexi to be exact. With this I bought 450 injectors, and a SAFC. Thank you guys so much. You guys are great.
