Smaller turbos will result in more torque, bigger turbos not as much. We will take a dodge srt4 for an example, makes 310whp 454wtq. But as soon as you go bigger turbo and add cams torque isn't as high, 420whp 380wtq. Rpms got pushed up bc of the slightly bigger cams which is a result in torque loss, you can also lose low end torque by switching intake manifolds as well.
And as for you to say 2.3 turbo could make more power, till you hit a certain amount of hp or big enough turbo then the 2.0 will make more due to it being able to rev higher and also bigger strong since the piston pin isn't moved up on the piston. And yes I have seen this happen when stroking a motor where the piston pin was too high on a motor with a turbo.
