IMO, no.

Spend it elsewhere.

hmm, i was going to go with a 85mm tb, but im not too sure anymore. I saw it as: If theres a larger opening for air to enter, especially using a turbo, than it would actually benefit and have better gains becuase its able to recieve more volume of air into the intake manifold. But you guys are saying its barely enough air for an increase of 6rwhp!?!?... the cost doesnt justify its ends, if true. Guess im sticking with the stock ported tb.

I think that's the best way to think about it.

My rule of thumb is you should buy 90mm stuff if you don't have anything yet, but if you have stock size stuff you can do a lot with it. I went LS2 + NW 90mm on the turbo Formula.
