Very similar setups (its nothing special, its cheap, its just about knowing what bits to do and why) do 725bhp/725lb/ft at 7psi boost, with 650lbft by 2500rpm and over 700bhp till 6500rpm.
Most people with similar setups run more boost (not loads, but 15-20psi) and a more suited turbo (the power and torque above is strangled hugely by the turbo being too "small") and it would give closer to 1k horses and well over 1k on torque, but its not a drag car and im not chasing numbers, full boost the second I touch the throttle, even at 2000rpm, is more fun, its being done to be used.

650-700 bhp+lb/ft, simple, reliable, and nice to drive is all I want as I know thats enough to keep me scared for ages, even though it would do tons more by upping the boost.
