If you have an auto, the IACV is a bear to retrofit. The wires had too much resistance and melted/snapped. The engine itself even with the throttle open a touch to compensate for the lack of an iacv wouldnt hold idle. I mean, if you had an ecu for the highport engine and the harness for it etc. then it would work but b15 ecu with highport engine will not work.
