OK yeah sorry i am in a rush and you guys have probably herd all these questions a million times i herd i can bore out my TB and i know where i can do it but will everything still work properly if i did that. if not where can i get bigger TBs what size do i need and do i need anything extra to go with it <sorry just another Newbie

you can bore it out to 59 mm or 62. but 62 mm is mostly for boost apps (Nitrous, turbo).
and you can ahve a local machine shop do it for you

Your better off buying it from a company like RSM Racing that has experience machining your throttle body because if that local shop doesn't do it properly your idle will be terrible and gas mileage will drop. Pay more money for good quality is what I say...

Good luck in your decision.

How is RSMs throttle body going to save you money from gas etc,? last time I checked boring out a TB is boring out a TB and you really cant screw it up. The only thing you can screw up is the flange plate that goes in it. I dont know why anyone would pay RSMs price when a local shop could do the exact same thing for around 100 bucks, its not a complicated procedure. Most performance or motorcyle shops do this stuff all the time.

just a few things...

you can screw up the plate, you can mess up on the adjustment idle screw, i;ve seen some leave the bored wall so thin, the minute the plate snaps closed it was like aluminum foil.

once you pass 58mm, on most of these 52mm TB, you risk going through the wall. there isnt much material, which is why rsm sleeves their larger bores..

true locally can do a TB, no doubt. jared/nitro bored his own, but had to putty a large hole bored into the TB vaccum .

if you are in a rush you might have to pay a premium. i waited overa month to get mine back, some longer, some less time. most major machine shops are doing larger projects especially in the spring so smaller things may be put on the backburner for some.

so what is the factory tb size for the ecotec engine?

From page five of the FAQ at the top of the page
2.2L 52mm
2.4L 52mm
2.3L 56mm
Ecotec 2.2L 58mm
