With the oem twin turbos? ...or an aftermarket turbo+fuel system setup?

Also, can I spray methanol? How about just water injection?

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.

Stock twins, 6spd: 350rwhp on pump gas
76mm turbo (or bigger), 6spd: 700rwhp on pump gas

However, with the 76mm turbo, running 15psi on pump gas, you'll be running 220rwhp until you hit about 5500 rpm or so. You'll be living in turbo lag city, and it'll suck donkey b@llz.

Can you see now why I was trying to find out more about your setup? There is no one clear answer...it depends a lot on the turbo you'l be running, and your application. Maybe rediculous turbo lag won't be a factor to you, if all you'll be doing is drag racing - just drop the clutch at 6k and keep it at redline through the whole 1/4 mile. Or maybe you want to stay with the stock twins because of the cost of a single turbo and fuel system upgrade, so you'll be stuck at 350rwhp. This sh*t ain't BS buddy...it's critical information and there's no way to properly and correctly answer your question without knowing it all.
