BorgWarner Airwerks S476SX-E (110/87)

The BorgWarner AirWerks S476SX-E – 76mm Enhanced S400SX-E 10087 Is Ready to Make 500 – 1200 HP

The 76.00mm S400SX-E turbocharger is the second-largest T4 turbo in the BorgWarner AirWerks lineup and is ideal for people who require more airflow than the GTX42R or S400SX 74.56mm but also want better fitment than GTX45R. Using state-of-the-art blade aero on both the 76.00mm inducer/100.00mm exducer compressor and the 87.37mm turbine wheel, this turbo is designed for use in high power and high boost 800-1150hp+ applications.

The S400SX turbos share identical fitment as GT42R (5″ inlet compressor hsg inlet and 4″ V-Band turbine outlet) and is ideal for applications looking for T6 levels of power but with T4 spool and fitment. Journal Bearing and Oil Cooled only (watercooling and BB CHRA not applicable).
