how much power?

[deigima]

i mean without methanol or water injection or any of that whatnot. yes, upgrading injectors and whatnot, but keeping the block internals standard. i dont think aftermarket turbos would be needed, since the most you can push without needing special injection is about 15psi,
so how much power NOT using methanol spray or water injection. preferably running 15psi.

Different sizes of turbos produce vastly different horsepower results at the same boost level. The bigger the turbo, the slower it needs to spin to push the same amount of air. Slower spin means less heat generated, which means denser air, which means more horsepower.
