BorgWarner 66.11mm S300SX-E 9180 – aka S366 SX-E

66.11mm SXE is the all-new update for BorgWarner’s legendary S366. ‘SX-Enhanced’ turbos redefine performance, durability and value for modern turbochargers. SXE turbos utilize latest generation billet compressor wheels, updated turbine wheel aerodynamics and up-rated 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 a traditional 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.
