Someone on eBay was selling a Vtec cylinder head from a 97 Accord EX, and was basically saying that to convert a non-Vtec car to Vtec, this head was all you needed. Dont you also have to have the ECU from an EX, or is it just the head swap?

 

i think you need an ecu from a vtec in general, cause it sends the signal to the sender for the vtec engagement, then i think you need a distributor for the same ecu, could be wrong on that on tho and of course you will have to run the wire for it
