turbo upgrade w/stock fuel system

Just the turbo? Yes. Up to fuel cut boost pressures, everything will still work fine. Beyond that, no it won't.

the hell is "stage 1"

some refer to it as a 54-57 trim upgrade. Some other shops refer to that when speaking of a t04 50trim compressor on a custom CT-26 format exhaust housing to allow it to bolt to the factory manifold. Either or, it's a hybrid. Peeps been doing it for years...not perfect, or even right depending on the dealer, but affordable.

thanks for the input. my turbo needs a new cartridge, and i was thinking about upgrading since it will only cost $100 more than just a stock rebuild.
i figure the extra flow will give me a little more to work with, and not a great cost if done now.
