S257 AKA 57/61 AKA 57-61 SX-E Super Core

This is a Super Core which means it consist of the center section, turbine wheel, and compressor housing and billet compressor wheel. Make sure to add in addition to the super core which size exhaust housing you would like to use. 

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.

S200 SX-E super cores contain the following exciting new features:
- Compressor cover integrated speed sensor port and pre-machined boost port
- Forged milled (billet) compressor wheels with extended tip technology
- Optimized compressor stage aerodynamics
- Interchangeable with existing turbine housings for upgradability

The BorgWarner super core assembly consists of the compressor cover attached to the cartridge, all cartridge to turbine housing mounting hardware, clamp plates, cap screws and mounting gaskets. Speed sensor and turbine outlet V-band are not included with turbo assemblies.  Choose a turbine housing from the drop down menu to add to your super core to make a complete turbo.
