Does anyone offer Throttle Body Porting???

I see people "porting" their TB's and it seems that all they are really doing is smoothing the ridge and polishing it.

I am curious if anyone actually ports throttle bodies.

I am trying to find the place that did my brothers 97 Eclipse, but I'm just surprised it's not more common for other cars.

Unless their physically is not enough material to allow porting.

hmmmmm

Formato offers porting for Throttle bodies and Intakes. Pretty sure they have an exchange program that is inexpensive.

Thanks guys for the contacts, I'll check 'em out.

But do you know off-hand how large they can bore the TB to?

Even if I can get the diameter at the butterfly to be around 80mm then I can shape the inlet and outlet to create a venturi effect. Well, the inlet is already tapered, but I can match up the outlet to the intake manifold.

Why don't you just buy a bigger TB?

I don't want to spend $350+ on an aftermarket if I can have this one ported. I will buy aftermarket if needed, but I want to try modifying this one first.

Also, I just like to play around. I may end up spending the same amount, but at least it will look stock and also allow me to pass on the information to others.

Really, I just want someone that can bore the TB and install a new butterfly, I can shape and polish the rest.

I haven't heard of anyone that has bored a stock TB. The casting must be too thin. If you could bore it larger, I'm sure somebody would have done this long ago.
