Ok, to sum this all up, do a search on the other "will an H22 work in a civic" posts. You'll find tons of comments regarding the fact that the H22 was never intended for a civic chassis. Here are some basic reasons:
1) the engine leans backward...all the 1.5 and 1.6L engines for the civics (both DOHC and SOHC) lean forward. Installing an engine that leans backward will alter center of gravity significantly.
2) the H22 and corresponding transmission weigh almost 200 pounds more than a SOHC engine and tranny, and over 100 pounds more than a DOCH engine and tranny. This added weight will cause extreme understeer, extreme overheating of civic-size brakes, and severe body roll even if you have coilovers.
3) the H22 requires cutting and welding in new engine mounts. This means that you can't ever go back to a D or B series engine once you've installed the H22. I guess you "could" reverse the process, but trying to weld in new metal patches where you've already chopped and weakened the frame is really risky.
Loosely translated, the H22 isn't feasable for anything except a full drag-race-only civic. It will do great in that situation, but trying to street drive or road race an H22 civic would require many thousands of dollars of chassis improvements to even make it feel like a stock civic. You'll never get an H22 civic to feel like a road race car.
A B-series engine can very easily be made just as powerful as an H22. It's lots more feasable, too. Go that route if you want big power. A ZC engine is a good start, but unless you've got a fully built block and over 10 PSI of boost, it won't ever feel like a beefed up GSR or B20.
