I'm doing some research on a swap and I'm looking for some input. Project Goal: 4th gen Hatchback with an HF transmission from a 4th gen CRX HF and a D16Y5 out of a 6th gen HX. Ok, you can start laughing now. My goal is a MPG cruiser with decent power and a little cargo space. From what I've found I'll need: Dual port to MPFI conversion OBD0 to OBD2a ECU subharness like this one from rywire: Rywire - Online Store From what I can tell, this looks like a plug and play swap. I don't need to worry about cable/hyrdraulic transmission issues since I'll be using an HF trans. Should I go D15Z1 instead? Any huge headaches ahead? Thanks for any input.
