Increasing the breathing of the engine with exhaust, intake and boost upgrades should do it. Check out Cobb tuning. http://www.caranddriver.com/features/five-steps-to-making-more- power-in-your-subaru-wrx-feature
Careful, as you may overpower the chassis, suspension, and tire/wheel setups. Watch the tuning so as not to stress the motor or turbo, eh? Try to aim for smooth power curves so as to not have an unruly "slingshot" from turbo lag.
