Anyone w/actual experience has tried/used a OEM or OS (oversized) ITR Throttle Body on their Boosted Set-Up?
If so is there huge gains vs. stock TB's (B16,GSR's). Or are they Minimal Results and not worth it?

Dyno's Graphs would be nice as well.

***The reason for a(n) OEM ITR T.B.... its Factory (B-Series) & Perfect for Daily Driven & response and most importantly No sticky plate!***

Well this was going to be my 2nd option. Since i got a xtra GSR TB sitting here.
I just want to know more or less is if the OE TB will have improvements vs. Oversize?

 

Oversized will help out with any FI setup...the more power you make the more difference it will make. But you CAN go too big (a maxbore'd stock TB will not be too big for any setup) and loose your velocity when the airflow demands are not high enough for your setup.

I recommend using an aftermarket intake manifold. Be sure to match manifold design to what powerband you want.
