    If it's gonna be a while before you do heads and cam then just do the LS6 for now. Huge difference.... But as the others said, once you upgrade those then you might as well put out the money for a Fast

    ls6 intake off of an 04 gto is cable driven, 3 bolt flange, I'd use your stock TB and port and polish it.
    FAST intake is either a 90 or 92mm throat and 4 bolt flange. heard lots of people say they use and love the Nick Williams 90mm tb for it
