BorgWarner AirWerks S200 SXE 7670 aka S257SX-E

BorgWarner ‘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 EFR7670, along with the same 57.2mm inducer / 76mm exducer FMW compressor in a purpose built S200 SXE compressor housing. Smaller overall packaging than the EFR7670 with identical airflow rates make this an excellent match for the 400-600hp range (up to 2.6L) or as twin turbos in 700-1100hp applications. Oil-Cooled Journal Bearing only.
