Would it fit? Yes. Would any person with a brain do it? No. You could do it, but tear the block apart, resleeve it and get smaller CR pistons.. but that defeats the purpose of spending 5500+ for it huh? Tranny isn't the perfect for boost either.. Go LS if your going to boost. Or resleeve a GSR, but find a damn good tuner also.
Where to get one.. Drag, RevHard, GReddy.. or there is a site where you make your own, i dont have the link, maybe someone will post it for you.
