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.

Why We Love It:

The SXE 7670 is one of the highest bang-for-the-buck turbos on the market, and one of the most popular turbochargers at Full Race.  Borrowing aero from the EFR 7670 while using the proven materials and durability from the S300SX-E series - this thing absolutely rocks.  A great turbo for any 4 or 6 cyl engine in the 400-580hp range.
