For a stock internalled engine, it probably isn't wise to go with a full race setup.

The drag kit offers a good amount of adjustability since you can upgrade the turbo with a larger t3/t4, so it could make the same amount of power but further down the road when the engine is built to handle that kind of power.

Edit: I also forgot to add that the wastegate provided with the Drag kit is a joke. It won't hold boost pressure for shit, so you should think about upgrading to a Tial.
