hey im getting a 2000 civic ex motor [d16y8] . im putting it into my 97 hatch dx. i have a few questions. if im using the harness from the y7 onto the y8 and hooking everything up..is there anything else i need to do? Im going to use the 96 ex ECU P2p on the 00 motor. what is air injection and will it do anything if i use the p2p from a 96?
