I hate when people get on forums asking questions without educating themselves or searching. That and they are all like OmFg!! I just watched fast and furious and I am ready to put a 100 shot of NAWZ on my VTECH accord!!! Take the time to learn about your engine, the tuning, and the components that are required to upgrade your car then post with an intelligent question.

On a more serious note, on an f22b1 with that many miles I would get it compression checked and take a look at the condition of the internals before considering upgrading the engine to make more power.
