Just wondering what all components on a given engine are obd specific. Distributor is an obvious but what about sensors, vtec solenoid, injectors, etc. I have an odb0 b16 head and wondering if I bolt it to an LS block, what all of the various elec parts must be specific to the obd of the chasis (in this case obd1) By the way, if this is an faq question, I couldn't find it and for some reason the search feature was returning an error. Could be because I am on a Mac. Don't know.
