Holset 3535215 Turbocharger Assembly

This Holset turbocharger assembly is engineered for the Cummins ISM11 10.8-liter inline six-cylinder diesel engine platform. The unit features a HX55W frame size with wastegate actuation for precise boost pressure control across the 280-500 HP power range. The compressor and turbine wheels are optimized for the ISM11's 125 mm bore and 147 mm stroke geometry, delivering peak torque of 2150 Nm. The center housing rotating assembly (CHRA) utilizes full-floating bronze bearings with piston ring seals for durability in heavy-duty cycles. The turbine housing incorporates a divided volute design for improved pulse energy utilization and transient response. This assembly meets Euro V / China National V emission standards when paired with the engine's high-pressure common rail fuel system and electronic control module.
