Ok, here's the thing, I have done some mods to my car since I have it :

- AEM Cold Air Intake
- Vibrant Catback ehaust with muffler
- Front Strut Tower Bar

- Pacesetter header and hi flow cat will be installed this week

Once this is done, I plan to get ,later, some other things , such as

- some nice rims (Probably the Fast - Rave)
- Lowered suspension (don't know which one : any suggestions will be welcome)
- Black Window tint

This will keep me busy for some time, but I don't know what should I do next. I don't want any visuals mods (I like it, but not on my car, I prefer to spend my money on performance parts). Does a larger throttle body would be a good idea after all that?? If yes what's next, the head?? Thanks for your help and suggestions.

of course its a good idea. you can buy a TB from RSM or have your tock one bored out. 59mm is good for NA cars. go 62 mm if you plan on boost.
after that you can get engine mounts, cams, pulleys, nitrous. whatever you want



Im a Xbox 360 fanboy...and damn proud of it!!

Which one of the two solution is the best (price and quality) : to buy a new one or to have my stock one bored??

not to jack ur thread but what is the stock TB at now? 58?

If 99redz24 said that 59 is good for N/A car, the stock one is probably smaller than that. Anyone know? I plan to get boost, but when everything else is done before such as pistons, cam, etc... So I should go with the 59 for now??? Consider that the boost will be later, a lot later. I'll be out of greens if I get it all done now

I've done a quick search about the 59mm throttle body, but when I saw interesting info about it the %$&# web site wasn't working. And the RSM website only show the 62mm. Is there any website or part number for a 59mm throttle body for an ecotec. Thanks
