Any Info on this would be greatly appreciated, I have just finished putting together my project engine.Cummins Big Cam III 400 That I am guessing will produce around 600 H.P. once I locate the right turbo. My pump is set up to 250 P.S.I. for now, Injectors are flowing 25% overfueled, Dual feed fuel lines, #12 fuel line from tank to pump with a V 12 fuel filter assembly in between to keep restriction down, I have retarded the timing on the cam, dual intake and dual exhaust. I think this little Pete 359 is gonna pull like a bear once I determine the correct turbo needed. Is there anyone out there that could give me a Holset turbo part number that would work with my setup. Or any input would be appreciated.
Thanks

My friend is running 300 psi rail pressure and 30% over injectors and he is around 500 hp. With what you are running I would think a BHT3B part #167715 would work. It has a broder MAP and more top end over the 30 year old HT3B design. If you need one let me know.
