If i want to port my throttle body, do i just use a dremel and go around inside of the throttle body untill its smooth? Any info will help. Im gonna do this once i get my truck back from getting new brakes on it.

That might take along time even with the right attachments. Having the right tools to do the job is a must. I have done research and have completed 2 without any major problems, besides alignment issues that have been resolved. I used a mill with a base that rotates evenly once that tb is centered to ensure proper porting. Then the fun part, polishing to a shine. And if you mess up, it's only about $350 bucks for a new one. Good luck!

What kind of benefit is there to porting and polishing? I have the machinery to do it. Maybe I should look into doing this.

More air? Sounds cool, when you smoke someone and they ask what you've got done, just tell them "ported throttle body, thats it" . Ricers would believe you.

They say you can feel a little better throttle response from better smoother air flow but im not to sure so i wanted to see if any of you guys have tried it before and if it was worth it or not.

Hmm... Well, dose anyone have an extra one just sitting around that they just dont know what to do with it they could just send it to me and I could try it out.
Dose anyone know what the bore size is stock and how big would one want to go with it?

I know that my stock 90mm was 82mm at the smallest points, it is now 92mm all the way through. !!CAUTION!! You have to make a new plate inside to make up the mm's gained from porting this much bigger or else engine won't run right. As long as you don't port any of the aluminum around the plate you don't have to worry about it but, whats the use, unless you go bigger. 10mm is the difference and I think I can get a couple more mm's out of this tb. I might have one that's already ported 4 sale.Originally Posted by Jeremy K
