Cummins ISX Turbo

The Cummins ISX engine is used in heavy-duty applications including semi-trucks for long-haul freight and a variety of other commercial vehicles.  These engines are known for their impressive power and efficiency which comes from their turbochargers. Cummins ISX turbos not only increase the power and efficiency of the ISX diesel engine but also improve fuel economy and help decrease emissions. If you need a replacement turbo for your Cummins ISX engine, HD Turbo can provide a remanufactured turbo that best suits your engine and vehicle.

HD Turbo provides remanufactured Cummins ISX turbos that can replace the turbo for your Cummins ISX engine. Our professionals meticulously assemble, calibrate, and balance each of our remanufactured Cummins ISX turbos so you can expect performance that meets or exceeds that of a new turbocharger.

What Does a Cummins ISX Turbo Do?

The Cummins ISX turbocharger is designed to boost power, torque, and efficiency in Cummins ISX engines, which are commonly used in heavy-duty trucks, semis, and commercial vehicles. It turns wasted exhaust energy into compressed intake air, giving these heavy-duty engines the power and efficiency needed for long-haul and vocational use.

• Enhanced performance: Cummins ISX turbos use exhaust gas energy to spin a turbine wheel that powers the compressor wheel. The compressor forces more air into the engine cylinders which allows the engine to burn more fuel efficiently, producing greater power output.
• Increased horsepower and torque: The greater power output increases torque and horsepower which is critical for pulling heavy loads, especially on inclines.
• Improved fuel efficiency: Cummins ISX turbos maximize combustion which improves fuel efficiency and reduces waste.
• Lower emissions: ISX turbos work in tandem with EGR, DPF, and SCR systems to meet EPA emissions standards.
• Variable geometry turbo (VGT): Most modern ISX engines use a VGT, which adjusts the exhaust vane position to optimize boost across RPM ranges. This also supports engine breaking and emissions control.

HD Turbo offers Cummins ISX turbos that are compatible with the following engines:

• CM870 Turbo
• CM871 Turbo
• HE561VE
• 2007 Cummins ISX Turbo
• 2006 Cummins ISX Turbo

When to Replace Cummins ISX Turbo

A failing Cummins ISX turbocharger can lead to serious performance issues, reduced fuel economy, and potential engine damage if not addressed. Below are the most common signs of a failing ISX turbo, especially in engines using Variable Geometry Turbochargers (VGTs):

• Loss of power: If you experience sluggish acceleration, lag in throttle response, or difficulty pulling loads or climbing hills, this could indicate low boost or stuck VGT vanes.
• Excessive exhaust smoke: Excessive exhaust smoke can indicate a problem as blue or gray smoke typically is a sign of an oil leak and black smoke could be a sign of poor combustion caused by low air-to-fuel ratio.
• Unusual noises: High pitched whining or siren sounds may indicate worn bearings, contact between turbine/compressor wheels and housings, or shaft play.
• Check engine light or fault codes: The check engine light could mean there is a problem with the turbo and ISX fault codes can let you know the specific problem, such as underboost and boost pressure not detected.
• Drop in fuel economy: The engine may burn more fuel to compensate for lack of boost and trigger regeneration issues if emissions systems are affected.
• High exhaust gas temperature: Inefficient combustion from low boost raises exhaust gas temperatures which can damage the pistons or the turbo system.
• Oil leaks: Oil residue around the turbo housing, compressor outlet, or inside the air cooler could indicate an oil leak caused by worn seals or excessive shaft play.
• VGT actuator issues: The electric or air-actuated VGT mechanism can fail, causing inconsistent boost, reduced exhaust brake performance, fault codes, and limp mode activation.
