So does anybody know of any larger throttle bodies for our car since I've searched a bit and came up with nothing?

If there aren't any out does anyone know the names of companies that make throttle bodies that I could e-mail about possibly making one for the Cobalt.

 

No one makes any

And no Saturn Motorsports Big Bore TB WILL NOT WORK

I emailed them already

 

60mm $295 for the 2.2L

Trust me, your throttle body size is just fine for your application and your current setup. Worry about drawing more air into your combustion chamber and keeping a good intake velocity more so than making things bigger.

If you did get an bigger throttle body, that will shift your powerband upwards and not necessarily make more power but just make power in different areas of your powerband.

 

i havent seen the bolt pattern of the ss/sc throttle body, but would it work, or are they about the same size

 

The larger TB will be a performace adder but at the cost of drivability.

IMO, working the intake manifold and air flow path would net you a much better return, The Big Bore TB is really the last step of a polish job.

The theory here is why make a larger hole, if the flow still sucks..

 

im with brian on that one. Get all the other aspects of the intake path upgraded. ported,CAI etc...
