Throttle body upgrades?
How big is the stock Throttle Body on a stock 2003 LS1? I see aftermarket throttle bodies in 92MM and 102MM right around $200.00. Is this overkill or can I gain a little HP with a bigger Throttle body ?

To run a 90+mm TB you have to have the intake manifold for it. Its will not bolt up to a LS1/6 manifold.
TPIS 90mm LS6 manifold
FAST 90/92/102 manifold
LS2 manifold (waste of money)
Oh yeah, the stock is 78mm.
