I have started this swap and ran into a question, should i do the ob2 conversion or should i just convert the engine over to obd1, my car has a makeshift wiring for vtec in it already but its not very nice, it looks very scetchy, anyway whats the opinion, what are my options any advice before i do something i might regret. oh yeah and i wanted to able to swap back to the z6 in a couple years for my smog check.
