Ported Intake Manifold and Bored throttle body

Anyone know of a company that makes or ports/bores a 1gr intake manifold and throttle body?

 

I've ported the lower manifold and upper plenum. It improved airflow through the motor, but only a nominal amount. You won't notice a difference unless you're motor is far beyond factory configuration.

 

This is sort of what I figured. The return is pennies on the dollar for the amount of work you would put into it otherwise.

The 1GR motor short of cam gears is pretty tapped out.

 

But my neighbor told me that his TRD CAI increased his HP by 75. I know I can be a dick but I chose not to ask him for a dyno readout.
