67mm Cossie Tb - Canadian ST - 04-08-2007
OK so this is the deal,
I have a 07 ST and im already needing more power, Im getting a Steeda SRI and I can pick up a used Cosworth TB for about $200. Is this a good idea? I've heard that if you put a bigger TB on your car needs a tune...,I dont know about that. I just want to free up some of the restriction I feel at higher RPM.
Can I get some feed back

I don't believe that the TB will do much more beyond sharpening throttle response and tip-in. Your best source of info for this is the Jet... specifically Walter Marcy of Marcy Motorsports and Randy Robles from FocusSport.

It seems to be that the power increases are somewhat there, but it's the overall "snappiness" that improves.
I'd recommend waiting on it until you get your SRI and exhaust installed. They'll enhance your feel for the TB. Stocker stuff will just deaden the effect and you won't really appreciate what you've done fully.
