I don't want to sound stupid or new when i ask this put what is the difference in a H22 engine and the one i have now. Also WHAT do i have now. ('90 Accord LX) If i wanted to change how much would it cost and would it be worth it. Just curious. Thanks

u have a a F22A and the big difference is the F22 is a single overhead cam and the H22 is a double over head cam. the other difference is that the F22A makes 130-135 hp and the H22 could make 195-220 hp.it would be worth it to swap out the F22A but i dont no the exact cost b/c ive never done the swap before. but from wat ive herd the H22A swap into 4th gen accords (90-93) is pretty straight forward.
