LS1/LS2 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
Or is there a different one I should be looking at? I'll post the specs on the engine since apparently my signature doesn't show
402 LS2- Callies Compstar crank/rods, Wiesco pistons, LG G5X3 114 LSA cam, LS6 heads (eventually replaced with TFS 225 or AFR 230), Edelbrock Victor water pump, Melling oil pump, Halltech air intake, Granatelli MAF (to be replaced with a 100mm), Jet-Hot coated LG long tube headers, Corsa Tigershark exhaust, AMW catch can, Hotchkis sway bars, Zoom kevlar clutch (being replaced with a Monster level 3 with Tick clutch hydraulics first week of March)

Quite a swing in $$$ there! What are your plans for the car? Are you still running a MAF sensor, and which one? For example, it doesn't make a lot of sense to spend all that on a 102 and then still have a 75 or 85mm MAF in front of it...
I believe I picked up my new LS2 dbw tb on ebay for less than $200, brand new, over 2 years ago.

I am having to do this in stages, as money for heads/intake/tb/rails/maf all at once is not gonna happen. I currently have a Granatelli MAF but plan on upgrading to a 100mm in the future.
The car is my DD, I am building my own version of the C5R over the next 5-10 years (LOL) and plan on keeping it as a DD. I have a LS1 intake/tb on it now and I know it is choking the life out of the engine, as evident by the poor dyno numbers and even worse hp/tq curve.
