The BorgWarner 72mm S300SX-E is the biggest turbo in the family, and it will deliver a lot of bang for your buck in high-horsepower applications.

The BorgWarner S372SX-E – 72.00mm S300SX-E 9680 Will Give You the High Horsepower You Crave

The BorgWarner 72mm S300SX-E is one of the best ways to get your engine to produce more power. Utilizing the latest generation 72.00mm billet EFR compressor wheel aerodynamics with uprated 360-degree thrust assemblies, the all-new ‘SX-Enhanced’ turbos redefine performance and value for modern turbochargers.

BorgWarner engineers started with their 72mm compressor wheel blade shape from the S472SX-E, but matched it with an S300 compressor housing 111lb/min airflow capability. This all-new wheel is packaged in a purpose-built SX-E compressor housing with a ported-shroud inlet and optional speed sensor port. A traditional AirWerks 80mm Inconel turbine and flexible housing options maintain consistency with existing installations. Smaller overall dimensions than the S472SX-E and equal airflow rates make this an excellent match for high-boost and high-power applications. Oil-Cooled Journal Bearing only.
