Fast Intake Help
I have been away for a while and need a kick in the *** in regards to the FAST intake manifolds.
If I understand correctly, the 90mm has been replaced with a 92mm for LS1, LS2 and LS6 models.
The LS3 and LS7 get the 102mm model that is coming out ?
What throttle body is recommended for use with the 92mm LS1/2/6 unit ? LS2 90mm ? Is this a direct bolt on ?? What kind of gains can be expected over a LS6 intake ?
Can you run LS3 heads on a punched out 427 LS2 Katech block and the FAST 102mm manifold on top ?
I need to be learned

Yes, the FAST 90 has been discontinued and the FAST 92 is the replacement. The new FAST 102 is for LS3/L92 cylinder heads and there's also a 102 for the LS7. The GM LS2 90mm TB works great with the FAST 92. All you need is the harness to make it work. The gains you get from the FAST will depend on the rest of your modifications. It will benefit the most on a nice set of CNC Ported Cylinder Heads. The LS3 heads need a minimum bore of 4.0.
