    It's a D16Z6 out of a '92-95 Civic EX or SI(aka "EG" bodystyle)

    You already have a vtec selenoid. if you didn't, you'd have oil pumping out of the backside of the head.


    The Green plug is your vtec oil pressure switch. The wire next to it (should have grey plug, but mine's ghetto rigged) is your Vtec Selenoid activation wire.

    You should be running a P28 ECU, which came in all of the '92-'95 civic EX or SI's.
    You'll need to buy a conversion harness for your ECU, b/c the p28's are obd-1(along with ALL '92-95 ecu's), and your car is obd-0.
    Boomslang Fabrication - Wire Harnesses for Fine Automobiles has great conversion harness' for $115 shipped.

    about the oil situation:
    Vtec needs more oil pressure when the runners open up, or when vtec 'activates'.
    If you don't have a vtec ecu, it's obviously not going to 'activate' vtec, and it will not use force more oil into your head, because it doesnt need to.
