Going from ls6 manifold to ls1
I know its weird to ask a de-moddin question in a performance oriented site, but hey theres alot of people that know their ****, so i always apreciate the advice. The reason im considering this, is because this is a really good friend that i woulnt mind help make his car faster. I wont benefit much money wise. And well as far as changing my car, well im gonna trade it in for something newer, so has no negative effect on me.
