OK, probably driveability, power/torque curve can be affected, and theoretically 1,0l should be less affected than 1,2l as it needs less air, but it depends also on airflow throught intake (intercooler, manifold, etc). Second question is reliability, as increasing turbo speed can increase power, but affect turbo life...
