They don't port match anything. They say they will but they just grind the inside. It cost me $800 to make that manifold and they didn't do half of the stuff I asked them to do.I asked them to port the inside of the runners cut the bosses and smooth the tank and runners for polishing. I even sent my lower intake manifold with gaskets to get it ported and port matched. I asked them to weld the talk to the runners also. The only thing they did was smooth the runners and cut the bosses and clean the inside a little bid. The TB is Velocity Element. I was going with hypertune TB but the shop I called said they have a TB from thailand that's almost as good but a bit cheaper so I gave that a try. This is the TB but it's a 70mm one. 90mm one takes longer to make. The good thing is that 90mm is the inside diameter and not the outside diameter like most 90mm tb out there.

After l got the tb I think I should have spent the extra $100 and went with hypertune. the quality is pretty solid but the flange is too thick IMO and it doesn't use O-ring gasket like hyper tune. I also think hypertune has more option with TPS. I had to get a TPS from thailand to use it on mine since it seems like the GTO-3000gts use different TPS there?
