Yikes I had a disco potato about 5 years ago and the wastegate exit was WAY bigger than that. You'll need an actuator too.

All you'll need is a manifold for an external waste gate provision and you'll have to run an external gate.. and a down pipe flange that covers up the waste gate hole on the turbine housing.
The Gt28's all had different choices for turbine housings so I guess the one you got i for an external gate.
That hole is the normal size for WG port. It's a small ass turbo so it doesn't need to be that big. Also to run an internal gate there is another piece, or housing, that bolts on the back of your turbine housing.
