If you get a 5th gen prelude, it'll have an h22 already in it. Put 3000 dollar turbo kit on it. why spend 3000 on a new engine for 20 more hp when you could buy a turbo kit and get like 100+ hp. Drive the stock motor for a while, prelude engines are quick to begin with, when you finally get one and drive it you'll realize engine swaps are really only worth it if your current engine doesn't work, or you have alot of money to spend.
