i dropped an h22 into my friends 93 prelude SI...it had an H23 in it and we just took out the old motor and put in the H22 and we used the old wiring harness and the H23 ecu...works fine...we are just waiting on his vtec controller so get the vtec up and running.

even with the stock H23 ecu...the H22 motor pulls harder than the old H23....even without vtec.
