Fast 90mm for high boost
The 102mm is suppose to handle it a lot better. I talk to FAST about high boost with their product. They said that in testing it was good for 60 psi, is what they told me. And they said they will stand behind that statement and there product. I said okay so if I blow mine apart you will replace it!? The man said yes, with the 102mm. So the 90mm and 92mm must not have done good. But I know a few on here that has been running FAST 92mm W/O problems. But then again they know what they are doing. 
In FI applications there is virtually no gain going from factory intake to FAST and your $ would be better spent elsewhere.

The factory style alum manifold has been done. It was not a big hit due to the weight and heat retention. The factory intakes do just fine with boost, have great heat dissipation, and are very light. I'm running one on my 1500hp build.
