Turbo came from Pittsburg power 8 years ago, don't know off hand whitch one it is, bought the Manifold when I burned out the center section, think it came from PP but not100% sure. If you turn up the fuel you need airflow to go with it or you will cook the motor, I did add a bigger radiator
So most likely you have the BW 171702 as I do. I haven't turned mine up past 500 yet but if I do it's getting a manifold and an EGT gauge for sure
