Remanufactured 3780090 Cummins ISL 8.9L Holset HE300VG Turbocharger with HOLSET OEM VGT Actuator

The 3780090 Turbocharger is a purpose-matched Holset HE300VG assembly for Cummins ISL 8.9L, Cummins ISC and L9 applications where specified. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3780090, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

This HE300VG unit is calibrated for Cummins ISL 8.9L applications used in motorhome, bus, vocational, and medium-duty service. The variable geometry system gives the larger ISL engine quick response at low speed while preserving the turbine flow needed during sustained load.

Accurate vane control supports boost, EGR operation, exhaust braking, and aftertreatment temperature management across a wide duty cycle.

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.
