ok so ive done some searching and cant find a ton of info on this but are there any companyies out there that make a larger throtle body for the ecotec's? if i remember right i think there were 2 companys and one was a 60mm and the other was a 62mm. on our factory throtle bodies whats the largest you can port it to?
I got mine off ebay, i forget how much bigger it was but it was a noticible differnce. I payed like 300.00 but it would probly be cheaper to got take your t.b to a machine shop and have them bore it out. But I have not found any companies that make aftermarket t.b for the ecotec.
i just sold my reveco throttle body on ebay for 150

what can you do with the stock throtle body? how much can they be ported out to? and when you port one i take it you have to get a new butterfly etc?
honestly if i were you i'd buy a cheap stocker for what 30 bucks and send it into smg.. they've got a good rep.. and it'll come back great.
