Borgwarner AirWerks S366SX-E Turbocharger

SX-Enhanced turbos redefine durability, performance and value for modern turbochargers. SXE turbos utilise latest generation billet compressor wheels, updated turbine wheel aerodynamics and Motorsport specification journal bearings with 360 degree thrust assemblies.

BW engineers started with their 91mm EFR9180 compressor wheel design, trimmed to 72% and 66mm for an airflow rate of 90lb/min. This all new wheel is packaged in a purpose built SXE compressor housing with ported-shroud inlet and speed sensor port. It is paired with an Airwerks 80mm Inconel turbine and flexible housing options. Smaller overall dimensions than the EFR9180 and higher airflow rates make this an excellent match for high-boost and high-power applications. Oil-Cooled Journal Bearing only.

The Highest Standard in Turbo Quality

Quality has been at the forefront of every decision we have ever made, a fact that was recognised in 1990 when we became the first British turbo re manufacturing company to be awarded the ISO 9001 accreditation. Today, it still remains the case, and that is why we carry out work for the majority of the OE manufacturers. We were responsible for the design of many of their quality system processes. From the design of our rigorous testing processes, to the choice of our brand partners, we are committed to delivering the very highest standard of quality of turbos, spares and advice to our customers.

Your ISO Guarantee.

ISO 9001 is an international Standard that acts as your guarantee that you will receive the same level of quality assurance and service from AET as you would do if you were dealing directly with the manufacturer.
