think it's best hogass to just hold out for a GT500 keep it stock lol

 

The problem with changing the throttle body is that we are limited to the small opening from our intake manifold. This will make any throttle body pretty much a waste of money since the diameter of the intake manifold will become the restriction.

 

What's the diameter of the opening on the intake manifold? If it's 68mm like the stock throttle body then this make sense. If it's 73mm or larger then it would not apply. Has anyone measured it?

 

I think the intake manifold is 3" or 76mm (isd) same as the tube going into the tb.
This is why the tb is a bottle neck.
looking at the intake manifold I would say it is 76mm or larger isd.
