These are the silver blade and open up the opposite direction of the newer LS7 and have been noted to tune better by some tuners.
Option 1 - Stock 90mm LS2 throttle body to be used solo or as a core for the TPiS 102mm throttle body found on here as well
Option 2 - Ported 90mm LS2 throttle body (details below)
The 87mm LSA throttle body leaves a lot to be desired. Our LS2 Throttle Bodies are the highest flowing, factory ported housings available on the market! We spend our attention on ultimate flow, unmatched dependability, and after-sale service. We have tested our throttle bodies on our in-house flow bench. We know what works! A mirror finish on the inside actually makes the air skip across the surface and creates flow turbulence, resulting in LESS flow!
