I have a d16z6 swapped into a 91 si rex but the vtec is not hooked up, what do I do to get it to work, I just recently got back into a honda and was never into the v-tec stuff
if you're using the stock ecu then you need to get a p28 which is the stock ecu for the z6. you will also need this. it comes with the wires and plugs that you need to run into the engine bay for vtec pressure, vtec solenoid, and 4 wire o2 sensor. Rywire - Online Store
