    100-200 bucks, you need a vtec ecu to work the vtec on the motor

    VTEC is controlled by the ECU. You could just put 12v to the VTEC Solenoid but that won't do you any good; You must be able to change Fuel and Ignition Maps under the new conditions VTEC creates. Best thing to do is to convert your car from OBD-0 (88-91) to OBD-1 (92-95). You can run either the P28 ECU (USDM Civic Si/EX) or the P08 ECU (JDM Civic VTi - This is what the JDM D15B VTEC motor came out of).

    P28 - 4 wire Oxygen Sensor Conversion; Runs motor okay, Built in PA Sensor, Emmissions controls
    P08 - Reuse 1 wire Oxygen Sensor; Runs motor best (meant for it), No PA Sensor, No Emmissions controls

    Email/PM me with any questions. I've done this swap a few times.

    BTW, I purchased my JDM D15B VTEC from HMotorsOnline.com for $495 a few years back. Freight Shipping from CA (his location) to NC (mine) made it about $700 or so. Great motor for the EF. Easiest swap for what you get IMO.
