Bore throttle body
 

Has anyone tried boreing their oem throttle body to fit an aftermarket intake manifold?

:confused:

There are some machine shops out there that will do this for you...I'm sure it works just as good as any aftermarket tb with the same diameter. But I don't know what the cost difference would be...

you cant bore a thottle body.... you can port match it, but it you make the throttle body diametee larger, the throttle plate wont seal...

Yes, you can bore a throttle body. Installing a larger throttle plate is an obvious necessary part of that process.

then at that point theres no sense it doing it, get a aftermarket one.

Either way, a throttle body nets minimal gains. if your concerned about it matching the port on you i/m then just get the return side ported to match.

Unless you work at a machine shop and parts/machines are free to use, then its not worth it.

actually it does make a difference to have the t/b bored out as long as the intake manifold is port matched and you have some other mods to support the use of extra air flow.

the only guy i know of that does them is gord bush...im sure there may be some one else
that can do it also but he does a pretty good job and his price is reasonable (less than the cost of a new aftermarket unit)

not worth it IMHO, just buy a bigger TB. i got a 70mm with a skunk2 IM to match.

Its hard to say if its worth it or not. Try calling the machine shop and see how much it'll cost.
