THE BORGWARNER AIRWERKS S200 SXE 7670 AKA S257SX-E IS SIMPLE, RELIABLE, AND POWERFUL
A cost effective variant of BorgWarner's EFR 7670, the ‘SX-Enhanced’ turbos redefine performance, durability, and value. Featuring the latest generation billet EFR compressor wheel aerodynamics and uprated 360-degree thrust assemblies, the 70mm Inconel turbine wheel borrows aero from the EFR 7670, along with the same 57.2mm inducer / 76mm exducer EFR compressor in a purpose-built S200 SXE compressor housing. A higher performing and heavily updated version of the old "S256" turbocharger, this BorgWarner turbo is 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.
