throttle body

Whats the biggest size throttle body made for the 2.2L <non-ecotec> cavalier engine. Do they make a 60mm?

Port your stock one out yourself..as long as you have some knowledge of cars you can port the tb out and your intake manifold to match and while your at it port your stock headers manifold too....all you need its a dremel and a porting wheel, which you can get at lowes or home depot....I've ported out a Thunderbird SC's superchrger this way as well as my 2002 cavy 2.2l it works wonders and is a lot cheaper then buying an aftermarket one..
