About the 90mm TB. Rob is the one who has build me one with a new TB housing. We wanted to be sure that everything works as accepted before we would let anyone in on this. I have been driving my car around a bit now plus I have done the dyno and I can say that it works great. I think though that people who are interested in this mod will need the custom intakes and the DCAI to make use of the extra air fuel. I think that some kind of pulley upgrade together with this mod requires bigger injectors and pump.

I can't say though how much the extra whp the bigger TB gets because I have had my car stripped down for almost a year and done all the mods at once.

I would be nice if someone else tried the bigger TB with before and after numbers to see the benefit.
