Steve @ 1 Posted November 22, 2007 Report Share Posted November 22, 2007 port match the lower to the upper manifold. u can also tidy up the lower to hear side but dont open it up to much. matched mine, whether it makes any real difference is hard to say. Link to post Share on other sites
FishWick 21 Posted November 22, 2007 Report Share Posted November 22, 2007 The real gains to a VR6's breathing come from larger valves and boring out the exhaust runners. Everything else won't really make much difference.If you imrove the head with larger valves, better cams and flowed exhaust runners.....I would recommend a larger plate throttle to match.
