best swap for the 90-93 accord, h22, which comes in preludes.....but, if you're on a budget, go with the f22, which came in several models, 94-97 accords, acura cl's....the f22 is a 2.2 sohc vtec motor, which i think is rated at about 140hp at the flywheel..no custom mounts needed, it will bolt right up...for vtec to work, you can either get the ecu from a 94-97 accord or just use a summit rpm activated switch....
