    OBD2 ECU, an OBD1 to OBD2 jumper harness for your ECU, rewire your distributor plug, wire up knock sensors, I think the SOHCs had the 4-wire O2 sensors, as well, so you need to change over to that....ummm...that's all I can think of off the top of my head, but I'm sure there's more.

    or you can use a

    p28 and skip knock because a p28 doesnt have it
    your harness and add vtec pressure switch and the solenoid
    convert to 4wire
    unpin and repin your old dizzy with the new one. obd1 has 2 plugs while obd2 is one, same colors either way
