there are about a 100 engine importers on the net.... just look up H22a...most of the motors you are going to find at the importers are going to be H22A1 which is the motor from the 92-96 preludes.....if you have a 5th gen 97+ their were a couple minor changes like a modified exhaust giving 5 more HP and a closed deck block design....
