Matching Throttle body to intake manifold...

I just bought an upper and Lower Cobra Intake Manifold, and am wondering what size throttle body is recommended for use with this. I have the stock injectors, a 76mm mass air meter, with a MAC CAI. Also headers, h-pipe (no cats) and catback ehaust. I know that going with too large a throttle body will negatively affect the performance of any car. I appreciate any help I can get....

just match it to the intake (65mm) opening if no future mods are in the works. if you plan on more hp down the road, get a 70mm and port match your current intake to it, that way you don't have a restrictive tb down the road.
