does a turbo have an internal wastegate or the turbo manifold have an internal wastegate? I was told I have an internal wastegate, have a t-25 turbo with a d-series turbo manifold, came from a top fuel turbo kit.

 

You more than likely have an internal wg.

 

The exhaust side of the turbo has the internal wastegate. If you look at that side, you'll see a flap door and that is what opens up via the actuator and vents off excess spent exhaust gases.

An internal WG in the manifold would not work since the manifold itself isn't producing the boost

 

Thanks, I have learned something new today
