500whp on a 2.0t

Guys I need help to see if this is a possibility.

Is it possible to make 500 whp on a 2.0t engine (Fsi)
Besides the obvious, fully built engine rods/pistons/top end, I was looking at the new garret g25-660 or g25-550 for turbo.

Is it possible to achieve 500 without meth or e85 by any method? Bigger injectors, secondary rail on ports? Is it possible to achieve it on 93 pump?

Hard to find this info out there, everyone goes the meth route.

Thanks for any opinion
Paulo.
