The Garrett G30 turbine housing kit with V-Band outlets and a 0.61 A/R for reverse rotation provides a turbine housing option matched to reverse-rotation turbo builds. It uses V-Band flange connections and specifies the 0.61 area ratio so tuners can select the housing that fits their turbine wheel and rotation direction for intended spool and flow behavior.
