Re: 2.5L power improvement
yeah, the stage 1, 2, and 3 kits are what I was talking about. I haven't bought them yet because I have very little money (poor college kid). I've heard that they make a difference but can't personally confirm it. Short of a supercharger, it is had to get much of a performance gain out of a 4 banger. Of course, every little bit helps.
