This unit was removed from a 400 cummins, rebuilt and balanced and was most recently used on a alcohol-injected tractor pulling engine producing in excess of 1200 hp. this unit will easily operate at high boost pressures and is right at home @50 psi. this unit has 5 runs on it since it was rebuilt and has had some custom work done on the thrust bearing as well as having the compressor wheel nut pinned to the wheel to eliminate the possibility of the wheel slipping on the shaft. THE ONLY REASON THIS UNIT IS BEING SOLD IS THE RULES HAVE CHANGED ALLOWING A LARGER TURBO THIS IS A BOLT ON AND GO UNIT NEEDS NOTHING!!!!!!!!!!!!!!!!!!!!!!!!

THIS TURBO IS A GREAT CHOICE FOR PERFORMANCE OR WOULD ALSO BE RIGHT AT HOME BACK ON A 855 CUMMINS DIESEL!!!!!!!
