its possible to get power out of the f22 but you have to remember this motor is in a family car. it was never meant to be raced or fully built, althought it is possible. you have to build up the bottom end like everything else if you want real power and then you could boost it pretty high i guess if you wanted. but why spend all the money when its much cheaper to get the power out of a h22 or f20b (euro accord). someone correct me if im wrong with this, but i figure its a little bit of common sense. any motor can be built to get power, its whether or not you want to spend all the money.
you could always do i/h/e, ignition, cam, etc for a noticeable change in power.... but its going to cost a lot more to get huge amounts of power
