throttle body

[predator5100]

Hey do they make bigger throttle bodies for our cars if so where can i get one

#1 you dont need a larger throttle body, the stock 3.8 one is huge already

#2 they don't make a larger one really. the GTP one modified might work but for just a few mm it won't do you any good.

I've heard the companies that make modified gtp throttle bodies can do something for our cars. I spoke to one of their techs. The stock is 65 mm, modified would be 67 mm. The cost was unreal like $300 plus core of ..... I don't remember but it was insane!!!!!

check FDP Performance. i think the guy's name is Franz. last time i heard, they were making a 62mm TB for the 3.4L FBody. plenum might need to be machined to match.
