you gotta remember one thing. The opening on the intake is still only going to be 78. So you can force all the air you want in up tot hat point its only still going to flow through there the same. So im thinking maybe just get your stock tb ported. you will see gains for sure on a stock ported TB. tons of vendors on here are doing it for dirty cheap these days. Most even do the bump stomp mod for you.

Port the stocker. The 90 MM TB won't fit without an adapter and won't do any good.
