Aesgarth is right. An H22 is a much larger engine. There are lots of mods that need to be done before installing the new engine. Not only that, if you're a lover of A/C, forget it. There won't be enough space for it. Your car will only be useful in straight line drag racing because it will be too front heavy for anything else. I know a guy who did the swap on his '93 EX coupe. Very tight fit. You will have to lift the engine to do some maintenance on the engine because the engine was never designed for Civic. If you can look pass the negatives, you'll be able to keep up with- even smoke - most V8s. No kidding!!!
