Who here has a aftermarket bigger Throttle Body on their Series 2? Is it worth it, and isnt it possible just to get one from a salvage yard, dremel it out, then slap it on in place of the stock TB?

i've put a L67 throttlebody on and it'* worth it. I wouldn't spend the money to get it done or bother porting a L36 myself either. You should just get a 99+ L67 tb, fill the coolant holes with metal adhesive, and ditch your charcoal canister or get a T fitting for it. If you get one from a scrap yard you'll save tons of money. But either way your gonna need a mini acf.
It'* a really easy cheap and simple mod that produces.

Do I have to do all of that? Its not possible to just unscrew the old TB, then screw the new one back on? I dont mind filling holes, but I got to remove the canister for it to work? acf is no problem.

if you remove the canister you can do FWI

Link or instructions on how to do that at all? Whats in that canister?

It purges the fumes from the gas tank I think, Damemorder has dropped his 2 inches

If you T the canister do you have to use the AFC, and problems associated with removing the canister?

Most who go for more air use the LS1 TB or the Northstar TB. Both of which will require a pcm or A/F modulator such as the Mini-AFC. If your looking for just a larger diameter there are some on clubgp that have ported their existing TB but you have to be careful.

A LS1 or North* is waaaaay too big for a n/a car.

I did an L67 TB on my '99 GT. I got it for $75 BUT don't try to to do this without some kind of tuning.
