does a turbo need a wastegate and a bov, or can it run on 1 or the other, or both?
which is better an internal wastegate or an external?

:cool:

both.
The wastegate controls bost, the BOV stops that boost taking the inlet manifold 3 feet away from the engine on overrun :)

An integral wastegate is better to prevent the turbo stalling. Distance between the impellors and the wastegate introduces a volume of gas which can make control less ideal.
