The BorgWarner AirWerks SX S300 turbine housing is specified with a 1.00 A/R and a 68mm inlet, designed to mate SX S300 turbine hardware to an exhaust outlet with a balanced A/R. The 1.00 A/R setting provides a compromise between spool and top-end flow, making this housing suitable for SX S300 turbo builds that target even response and sustained flow across the operating range.
