Every engine is different, but what really matters is AFR and airflow. Any specific answer to your question would be a blind guess.

to give you an idea of what i've read on all e316g turbo threads, it's pretty rough to hit 300hp, but very possible. The main thing you'll need is a dead on tune. You didn't list a FPR, if you don't have one you might want to get one so tuning is even possible.

Its very easy to hit 300whp at around 17psi on a 16g and pump gas. Getting anymore is a little tough on pump. Race gas, or injection helps this.
