Waste of time and money. Basicly your going to go through the hassel of converting the civic engine bay to accept an H-series (mount kit, cable shifter), but you'll end up with a shitty 140 hp F series. Depending on the trim civic you have, you'll see a 15 hp boost if you have an EX civic, and about 35 hp boost if you have a base civic. My advise if your not looking to spend alot of money, swap in a b18b in there. Plenty of trq, and overall a strong engine with lots of room for improvement. In addition, they are MUCH easier to swap into a civic engine bay.
