BorgWarner EFR & AirWerks Turbos

Shop BorgWarner turbochargers, SuperCore assemblies, turbine housings, and turbo service parts at Black Ops Auto Works. Explore selected EFR, AirWerks, S-Series, and K-Series components for performance builds and application-specific replacement projects. Choose each part using the exact BorgWarner part number and the requirements of the complete turbo system.

BorgWarner EFR Turbochargers

The EFR range includes complete turbocharger configurations and separate components for builders selecting a specific compressor, turbine, and housing combination. This collection includes selected 6258, 6758, 7163, 7670, 8374, and larger EFR configurations.

Compare turbine housing A/R, inlet flange, single- or twin-scroll layout, wastegate arrangement, and bearing-housing configuration. Two turbos carrying the same EFR model number can have different installation requirements and operating characteristics.

AirWerks and S-Series Turbo Components

Explore selected AirWerks and S-Series products, including SX, SX-E, and SX-R configurations. BorgWarner's AirWerks range uses journal-bearing technology, with different compressor and turbine combinations available for specific airflow requirements.

Choose the turbo around the engine's operating range, airflow demand, and intended use rather than a horsepower estimate alone. Review compressor maps and the complete system with your builder or tuner. Browse our forced induction components for related hardware.

SuperCore Assemblies and Replacement Cartridges

A SuperCore is not necessarily a complete installation-ready turbocharger. Depending on the configuration, a compatible turbine housing, clamp hardware, wastegate components, and installation parts may be required separately.

Replacement cartridges are another distinct product type. Match the cartridge to the exact turbo assembly and confirm bearing-housing material, wheel dimensions, and connection requirements. Do not assume a cartridge and SuperCore include the same components.

Turbine Housings and Compressor Covers

The collection includes selected EFR and S-Series turbine housings with different A/R values, flange arrangements, and wastegate provisions. Compressor-cover options are also available for specified EFR applications.

Match the housing to the intended turbine wheel and center assembly. A shared flange or similar external shape does not establish internal compatibility. Confirm inlet and outlet connections, housing orientation, clamps, and clearance before ordering.

Vehicle-Specific Replacement and Upgrade Turbos

Selected listings cover Duramax L5P, Cummins, Power Stroke, Audi, Volkswagen, and MINI applications. These products can include replacement components or upgrades with different supporting requirements.

Confirm the engine code, production range, original turbo number, actuator configuration, and calibration requirements. For left- and right-side turbo applications, identify the required side explicitly. An upgrade listing should not be treated as an unchanged factory replacement without reviewing its instructions.

Wastegate Hardware, Sensors, and Service Parts

Complete compatible assemblies with selected actuator brackets, boost-control solenoids, speed sensors, clamps, repair kits, and installation hardware. Match each accessory to the specified turbo family, housing, and mounting interface.

A repair kit does not by itself establish that a damaged turbo can be returned to service. Have the assembly assessed by a qualified turbo specialist and follow the appropriate inspection, balancing, and setup procedures.

Before You Order BorgWarner Parts

• Confirm the exact BorgWarner manufacturer part number.
• Distinguish complete turbos, SuperCores, cartridges, and housings.
• Match compressor and turbine dimensions to the intended assembly.
• Verify housing A/R, flanges, scroll configuration, and wastegate type.
• Check oil, coolant, intake, and exhaust connection requirements.
• Review actuator, sensor, bracket, and calibration compatibility.
• Confirm included components and required supporting hardware.

Frequently Asked Questions

Is every BorgWarner turbo a direct replacement?

No. Some products have specific replacement applications, while others are performance components requiring a matched system. Confirm the complete part number and installation requirements.

Does an EFR SuperCore include a turbine housing?

Do not assume it does. BorgWarner identifies turbine housings and other hardware separately for EFR SuperCore configurations. Check the package contents for your exact assembly.

Can I interchange housings with the same A/R?

No. A/R alone does not identify fitment. Wheel dimensions, center-assembly interface, flange design, and wastegate configuration must also match.

Are aluminum and iron bearing-housing versions identical to install?

Not necessarily. Cooling and attachment requirements can differ. Follow BorgWarner's instructions for the selected version rather than transferring assumptions from another assembly.

What should I check before replacing a failed turbo?

Identify and correct the cause of failure first. Inspect the lubrication system, intake and charge piping, intercooler, exhaust path, and other affected components for restrictions, contamination, or debris before installation.
