It takes 313 tq to make 180hp at 3k.
Posting this just for comparison, i know mine is 3.6, but even with the bigger capacity and little K16 turbines, 1.0bar is around 3500rpm. You'd need a turbo so small to get 1.0bar at 3000 that it wouldn't give you power up top

This is the boost on a GT4088R, with a 3.4ltr engine, wild cams, big ports, thin valve stems etc etc... It's nearing 5000rpm before 1.0bar
