and btw aaron, j's, spoon, etc they dont' have stickers or markings on their TB, so you don't even know it's from them

 

but i can put J's Throttle body on my MOD list

 

You can remove your stock throttle body, take it to a machine shop and have it bored.

 

do u know any good machine shop in bay area?

 

I will research tonite.

 

You would most likely have to send it out somewhere.

 

Thank you

 

Here's one company They have them in stock and ready to go for $155.00

 

Don't forget a new, larger throttle plate also has to be fabricated. A most critical operation. Proper design of the plate can have as much or more affect on performance than the larger bore. The plate is always in the air flow while the increased bore is only helping you at wide open throttle.

 

What is the stock throttle body bore size?
Is it true if you go to a larger bore size you may gain horse power but lose torque?
