I am guessing this is going to be a track only car? As the turbo you will need to make that much power will be useless on the street, also with that much power you will never be able to use it on the street because all you will do is spin. Besides the motor, what are your plans for the clutch, axles, transmission, injectors, motor mounts, cooling system and so on? It is not to hard to make that much power but to keep the motors together and the rest of the car together is where it is going to get expensive. I would just find an ls or gsr block sleeved unless you are set on getting a b20 sleeved.
