Yea what Mike said about the Pro2's being too big. The Pro1's are nice but you will have to be able to tune the car. We put a set in a B16 and was almost impossible to get to idle. Pro1's have a very aggresive low cam so Vtec is normally moved up in the rpm range. Also, remember that if you want to take advantage of the top end gains you need to have a good header and exhaust to be able to flow enough. Later.
