I have an '88 DX sedan with an auto that I want to keep for now. I also have a D16Z6 head and intake mani that I want to put on the D15B2 block. Is it easier to get a PS9 and a VAFC for VTEC, or upgrade to OBD1 with a P28 and conversion harness? I don't have the engine harness or injectors yet, so I can still go either way easily, but I have the block, head, and intake mani already. Any suggestions on which is easiest? Also, where can I find a PS9 if I decide to go that way?
