First off, im new to honda swap.com and have a tech question that i need to figure out before i start doing things backwards. I WILL be searching aswell but figured posting this is not going to hurt either. so im taking my d15 non vtec out of my 89 CX hatch and putting in a D16z6(d16a6 bottom end) Engine came out of an SI CRX which was running a PM6 ECU. Vtec was never wired up. Im planning on running my OBD0 PR3 and dont want to change to OBD1. So my questions are: Is it going to be easier to use my CX wire harness or should i use the CRX si harness? My PR3 does have the conectors and wires still so im going to be splicing on of these engine harness regardless. The d16z6 is already MPFI so that part saves me some time but im just trying to get some solid answers regarding this swap. I do appreciate any help/reccomendations BESIDES converting to OBD1.
