i doubt the guy is making 300 horse, and dont listen to the h22 haters. they are just uneducated. it weighs like 50 pounds more, just get some stiffer springs and lighten up the front a little and your fine. its a good motor w/ lots of torque and power. its a bit of a squeeze into the engine bay, but it fits fine.
also.. theres tons of topics on the h22 already.
