210hp seems a bit low

Attached piston acceleration chart comparing 2.0L v 1.6L @ a range of RPM

Compression ratio on the 1.6L is also lower @ ~9.1 (16A) vs ~11.1 (20A) so you should be able to dial up the boost more (the turbo is going to be able to handle given the lower displacement engine means you can roughly make the same boost as the 2.0L at a higher RPM, pushing power band higher up)

Breathing (Air flow rate through the system) should absolutely not be an issue as all the intake plumbing from filter to the valves are identical to the 2.0L. Meaning you should be able to pump the same amount of air as the 2.0L. The limit is whether the rods will be able to handle.

This next part is a bit seat of the pants but relative to the 2.0L if you can bump the RPMs by ~1000 you should only have about 15% lower peak power assuming you don't increase boost to take advantage of the lower CR.
