the h22 swap has been talked about a LOT here. try running a search and read on.
there are basically two sides of the story. the h22 is pretty much the largest displacement 4 cyl. honda engine you can find. its big displacement makes it a good fit for straight-line performance. however, because of the big displacement, the engine weighs more than b18s. this, in turn, ruins the weight distribution of the car when swapped into a teg which is very nose heavy to begin with. after spending all the money in the engine swap, you've got yourself an ill-handling car that understeers a lot. then you've got these people that say you can mod your suspension to compensate the additional weight of the engine. my view on that is - sure. with enough money, anything is possible. but i don't think i'd want to spend thousands of dollars after spending thousands of dollars swapping in an engine.
whatever you want to do with your car, as always, is up to you. if i were you, i'd stay away from the h22 swap. i don't have that kind of money anyway. if i really had to get another engine, i'd just get a relatively new b18b which is drastically cheaper than b18c1 or b18c5. with the money that's leftover, i'd boost it. but then, that's just me. again, it's all up to you. your car. your money.
