The Garrett G30-900 reverse rotation turbocharger is engineered for builders demanding high-flow performance with the layout flexibility that reverse rotation and V-Band connections provide. Built on Garrett’s proven G Series platform, this unit is suited to serious performance applications where precise housing orientation and rapid response matter as much as top-end capability. It’s the choice for enthusiasts and shops building a turbo system around specific packaging and flow requirements rather than settling for off-the-shelf configurations.

Performance & Application

This G30-900 configuration is built around a 0.72 A/R compressor housing paired with a 1.21 A/R O/V turbine housing, giving builders a turbine housing option engineered for strong exhaust flow characteristics. The reverse rotation design and V-Band inlet/outlet connections on both the compressor and turbine sides make this unit well suited to installations where housing orientation and clocking flexibility are critical to the overall turbo system layout. Ball bearing construction underpins the unit’s responsiveness, making it a strong fit for builds that demand both quick spool characteristics and the ability to flow at higher levels.
