BorgWarner Airwerks S363SX-E (8876)

BorgWarner S363SX-E – 76mm the sweet spot of the SX-E family

The 63mm inducer ‘SX-Enhanced’ 8776 redefines performance and value for modern turbochargers.  Utilizing BorgWarner's EFR compressor aero with 63mm inlet, this reliable design flows up to 78.5lb/min at 122k rpm. This is paired with the legendary Airwerks 76mm S300 Inconel turbine wheel for great spool and flexible turbine housing options to fit a variety of builds.  The bearing housing is an oil-cooled journal bearing with uprated 360-degree thrust assemblies.  If you need 500-700hp worth of reliable airflow and don't want to break the bank, this is your turbo.
