    ^_^ I bought a 1990 crx Si that had a SOHC Vtec Zc swap done to it, When i bought it it had no Vtec solenoid and it had the stock ECU on it, And i was wondering if i put the vtec on it what ECU will i need to use and will i need to get a different wire harness for it?

    You sure it's a VTEC engine to begin with? If it has the stock ECU, you'll need to swap the distributor and get a OBD0-OBD1 conversion harness and a a P28 or P30 ECU.
