The BorgWarner AirWerks SX S200 T4 twin-volute turbine housing is specified with a 1.15 A/R and a 61mm inlet, configured to mate SX S200 turbine geometry to a T4 exhaust flange. Its twin-volute design channels exhaust pulses separately to influence spool and midrange flow. This housing is intended for builders who need a direct-fit SX S200 turbine housing with 1.15 A/R for T4-style installations.
