which intake do you have fir that quad....and is this the HO motor. If you really want to build it lemme know I have owned Two GTZ's with Quad four HO motors in them and I have alot of parts and access to a ton more that are extremly hard to find. If you have an early style HO quad then your already pushing 180hp Which will hand most Imports thier asses, but i doubt thats whats in there. The intake mani tells the tail. If you have a manifold that looks like 4 Snakes rapping around each other than you have a base quad. Lemme know what your thinkin of doing and i can get a lot of stuff specific for that motor and you can get some significant power. Just dont expect reliability
