What do I need to do to build a 1000hp turbo small block

dollar for dollar it will be half the price of a mopar.. A 6liter can be had for 1500 with a moded harness and ecu, studs, cam, methanol and 20lbs of boost is stable to over 900. It is all in the tune... Her is a stock botom end 5.3l with over 700 at the tires.
