BorgWarner S200 SXE T3 Inlet & V-Band Outlet

Utilising the latest generation aerodynamics, billet EFR compressor wheels, and motorsport specification 360 degree thrust bearing, BorgWarner’s all new SX-Enhanced turbos redefine performance, durability and value for modern turbochargers.

BW utilises their 70mm Inconel turbine wheel with 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 a sensible match for the 400-600hp range (up to 2.6L) or as twin turbos in 700-1100hp 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.
