Ok I have 2 heads that I can use. One is a P2J-2 Y8 AUTO that is port and polished with a Crower Stage 2 turbo cam. THe other is a PO8-8 Z6 head that is completely tore down but has Vtec solenoid and throttle body with it. I purchased a OB2B to OBD1 harness and I have a chipped P28 ECU to go with the build. I am putting either one of the heads on a Y7 2000. I am all screwed up now because I bought a bunch of parts for a y8. Can I use the TB and the IM on the Y8 head? Does it really matter if the head came off of an automatic or a manual transmission d-series. All I know is that I need a vtec solenoid for my y8 Head.....Pleas Help
