Ive got the stock motor. (F22 or something) I put rsr exhaust, DC headers, Aem pulleys, Injen cold air intake, and Exedy stage 2 clutch.I was happy with the hp for the buck. But now I'm getting mileage on the motor and I was thinking about the H22 swap. Im at 172,xxx now and I don't want to mess with the internals. What are some thoughts about it. How easy is it, and can I at least keep my clutch? Let me know anything, I'm new to hondas and I got a deal on the car. It is really clean and has suspension with tie bars and stuff too. Tell me what you know.
