BorgWarner Airwerks S252SX-E Turbo (SXE7070)

The BorgWarner AirWerks S200 SXE 7070 aka S252SX-E Will Bring You Affordable Power

Utilizing the latest generation aerodynamics, billet EFR compressor wheels, and uprated 360-degree thrust assemblies, BorgWarner’s all-new ‘SX-Enhanced’ turbos redefine performance, durability, and value for modern turbochargers. BorgWarner utilizes their 70mm Inconel turbine wheel with 52.2mm inducer / 70mm exducer FMW compressor in a purpose-built S200SX-E compressor housing. Smaller overall packaging than the EFR7670 with identical airflow rates makes this an excellent match for the 350-500hp range (up to 2.5L) or as twin-turbos in 600-900hp applications. Oil-Cooled Journal Bearing only.
