What are your final power goals?

If you're doing a compound boost versus a take over, you need to be aware that the turbo will need to be capable of providing the airflow you need at the boost levels that the turbo alone will be running at.

So for instance if you're running the supercharger at 9 psi and want a final boost level of 24 psi, let's say, the turbo will max at about 10 psi, so if you want a top end power level of say 500hp, then you need a turbo that can push 50lbs/min at 10 psi. a GTX 3076r doesn't provide enough air at that level.

The reason a lot of people don't compound boost is that you'd have better top end power by using a turbo alone. With a smaller displacement engine like a 2.0l though the torque curve is so much better that it becomes well worth it if you get it working right and size the turbo appropriately.
