What size TB?

[davidf]

Well I want to replace my stock TB but don't know what size. Maybe a TB/plenum combo along with RJC's powerplate. I really want this mostly for the cool factor:"NEW" Champion Complete Intake, Heads & Intake, HEGN1-6000A | Cotton's Performance Buick Grand National Parts & Service
Is it a big waste of money for the street. Thanks.

Go for a custom 102mm or dual 75's. that would be really cool:biggrin:

Get Steve (Stevemon) to open it to a 62mm & polish it. Helps throttle response & looks nicer.

if you port the tb make sure the plenum is the same size otheir wize you can get reversion
