Throttle Body questions
I have a "Shaner"-ported throttle body on my 97. Since the addition of my supercharger, I'm curious if there is difference between this, later model LS1/LS6 throttle bodies, and the LS2 version. In particular, I'm looking at the interior diameter for more flow and faster throttle response for less pedal pressure.

The LS2 is a 4 bolt 90mm tb and will only bolt up to a FAST 90/92/102 or a TPIS modified LS6 manifold. You would also have to have the harness to plug into the LS2 TB.

I agree you are best advised to leave the one you have alone---it's plenty big for 90% of all applications---also to go bigger you'd need to replace your manifold to a newer style to accomodate a 90MM TB's AND if you don't have your own tuning software it will create all kinds on idling-surging and dieing issues
