BorgWarner 12709882081 B2BV SX-R Turbocharger for 2017-2019 GM 6.6L L5P Duramax

Vehicle Fitment

• 2017-2019 Chevrolet Silverado 2500 HD (6.6L L5P Duramax Diesel V8, AWD/4WD)
• 2017-2019 Chevrolet Silverado 3500 HD (6.6L L5P Duramax Diesel V8, AWD/4WD)
• 2017-2019 GMC Sierra 2500 HD (6.6L L5P Duramax Diesel V8, AWD/4WD)
• 2017-2019 GMC Sierra 3500 HD (6.6L L5P Duramax Diesel V8, AWD/4WD)

Fitment Notes

• Fits 2017-2019 L5P Duramax only - 2020-2023 L5P uses a revised actuator and connector orientation; use BorgWarner PN 12709882080 for those applications
• 2017-2019 and 2020-2023 L5P turbochargers are NOT interchangeable due to actuator and connector differences
• Direct-fit upgrade built on the OE BorgWarner B2BV platform - no modifications required
• Replaces OEM part numbers: 12709701044, 12709701026, 12709701050, 12709801050, 12709701051, 12709801051, 12709701076, 12709801076, 12709701079, 12709801079, 12709701081, 12709801081
• Supporting modifications (fueling, tuning) recommended when operating near or above 500 HP

Features

• Built by BorgWarner - the OEM turbocharger supplier for the GM L5P Duramax from the factory
• SX-R compressor aerodynamics with updated blade architecture for improved airflow efficiency across the entire map
• 64.0mm forged milled compressor wheel (FMW) - lighter and stronger than cast aluminum for faster spool-up and increased durability
• Extended Tip Technology delivers the flow of a larger compressor wheel with the lower inertia of a smaller wheel
• Variable geometry turbine with electronic actuator for precise, PCM-controlled boost management
• Direct bolt-on fit - correct actuator orientation and OEM-matching electrical connectors for 2017-2019 applications
• Supports up to 600 HP with appropriate supporting modifications
• Arrives fully assembled with new actuator pre-installed - no actuator swapping required

Product Description

The BorgWarner 12709882081 is a direct-fit B2BV SX-R upgrade turbocharger for the 2017-2019 GM 6.6L L5P Duramax. Built by BorgWarner - the same company that engineered and supplied the factory L5P turbo - this unit upgrades the compressor side with a 64.0mm forged milled wheel and SX-R aerodynamics while retaining the factory variable geometry turbine and electronic actuator for seamless PCM integration. The result is a plug-and-play performance upgrade rated to 600 HP without sacrificing drivability or daily reliability.

Unlike universal or heavily modified turbo upgrades, this SX-R unit uses the correct OE actuator orientation and electrical connectors for 2017-2019 applications, making installation straightforward. It arrives fully assembled with the actuator pre-installed and includes a complete gasket kit. Note this part number is specific to 2017-2019 models only - the 2020-2023 L5P requires BorgWarner PN 12709882080 due to revised actuator and connector design.
