62mm Tb

[FutureEcotecOwnerAgain]

I have a wai from rksport and a pacesetter header with 2.5 inch piping from cat back. would it be worth it to buy the 62mm tb from rsm racing or do i need a supercharger or turbo? just wanting to know it the performance gains would be worth the money.

so are you telling me with a wai, header, cat back exhaust and 62mm tb i'll be beating mustang gt's? i know the hp will be around 170 to 180 when stock its only 140, but thats kinda crazy. or do you think i have the 3.4?

[Pimpalero03]

lol no u wont. i dont think a 62mm throttle body is going to do anything for u really. unless u have a ported upper intake and cai maybe?

you will notice a difference but it wont be extreme, you will notice it a lil more if you ported both lower and upper intake manifolds to match......and even then its not a neck snapping difference.....

hey he has a 2.2 ecotec not a 3400 its only a one piece intake

If you have the manifold, put out the extra cash for the TB.

You'll notice a difference since you have the manifold already.

Your only allowing as much air as your smallest opening will allow :thumbsup:
