The BorgWarner AirWerks SX S200 T4 twin-volute turbine housing features a twin volute design with a 0.83 A/R and 61mm inlet, built to pair SX S200 turbine geometry with a T4 exhaust flange. The twin-volute layout separates exhaust pulses to improve transient response and spool characteristics for compatible turbo builds. Use it when adapting SX S200 internals to T4 exhaust configurations.
