BorgWarner Airwerks S257SX-E - 57mm Enhanced S200SX-E 7670 Turbo

The BorgWarner AirWerks S200 SXE 7670 aka S257SX-E Is Simple, Scalable, and Strong

BorgWarner's ‘SX-Enhanced’ turbos redefine performance, durability, and value. Enhanced SX turbos feature the latest generation aerodynamics, billet EFR compressor wheels, and uprated 360-degree thrust assemblies. 

The 70mm Inconel turbine wheel gets aero from the EFR 7670, along with the same 57.2mm inducer / 76mm exducer FMW compressor in a purpose-built S200 SXE compressor housing. Smaller overall packaging than the EFR 7670 with identical airflow rates make this BorgWarner turbo an excellent match for the 400-600hp range (up to 2.6L) or as twin-turbos in 700-1100hp applications. It is oil-cooled journal bearing only.
