Lots of folks pick up a used LS2 90mm unit, and do some mild port and/or polish work to it. I've also read nothing but good reviews on Nick Williams throttle bodies. Just Google Nick Williams, and you'll find all kinds of information.
I've read that many people have issues with the Fast 90mm TB, more specifically fit and finish issues that cause the throttle blade to stick open at WOT.
Hope this helps.

Since you have a 92mm intake, you need to go with either a 90mm or 92mm TB...anything larger than that, even if you could get it to bolt up, would be a waste and/or hurt performance.

How about putting a vacuum guage or manometer across the throttle body, and measuring the pressure drop across it at WOT? This would give you a baseline, and tell you if an expensive replacement TB is worth it.
