Default LSX throttle bodies
I am going to be putting a FAST 102 on the 402 LS2 in my C5. I have been looking at the available throttle bodies, and am just not sure which to go with. I am currently looking at these:

TPiS 90mm 1500cfm http://tpis.com/parts/view/53
TPiS 102mm 1800cfm http://tpis.com/parts/view/260
GM LS2
NW 102mm LS1 or LS2 style

Engine specs: 402 LS2, 11:1 compression, LG G5X3 cam, triangle casting LS6 heads (will eventually be upgraded to TFS heads) .

Or is there a different one I should be looking at?

Either one of the 102s would be good, they are good brands

IMO, you can't go wrong with the NW TB's, and you can get a NW 96TB for a good amount less than NW 102TB.

Camaro/Firebird throttle bodies have a traditional throttle cable, like on every TPI/TBI/carb engine.

Corvettes (not sure about GTO's) are Drive By Wire. They have a sensor on the gas pedal that sends a signal to an electric motor on the throttle body that in turns opens the throttle blade to what ever % the gas pedal is pushed down.
