Remanufactured 3792327 Cummins ISB 6.7L Holset HE300VG Turbocharger with HOLSET OEM VGT Actuator

The 3792327 Turbocharger is a purpose-matched Holset HE300VG assembly for Cummins ISB 6.7L, Cummins QSB 6.7L medium-duty and industrial applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3792327, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

This HE300VG family turbo is calibrated for Cummins ISB/QSB 6.7L medium-duty and industrial applications. Its variable nozzle mechanism changes the effective turbine area as engine speed and load change, allowing quicker low-speed boost, controlled exhaust backpressure, and engine-brake support while still providing the airflow needed at higher load. The turbo-only and complete-actuator versions use the same core turbo calibration but require different installation procedures.

This complete version includes a HOLSET OEM VGT actuator matched to the turbocharger. The actuator and vane mechanism are checked for full travel and correct indexing so the assembly can be installed as a complete unit; the vehicle's required calibration or learn procedure must still be completed after installation. Turbo Centre remanufacturing begins with complete disassembly and thorough cleaning so every critical surface can be inspected. Worn bearings, seals, and service components are replaced; shaft, wheel, housing, and vane-system condition are measured; the rotating assembly is balanced; and the completed turbo is checked for smooth operation, oil sealing, and correct control movement before shipment. This process restores the unit as a complete engineered assembly rather than simply replacing the visibly damaged component.
