Turbine Housing, Garrett G25-EXT W/G REVERSE, .72 A/R w/ Vband Entry/Exit PN: 740902-0073

This Garrett G25 turbine housing is engineered for reverse-rotation, externally wastegated applications where standard rotation simply won’t work with your exhaust manifold layout. Built for custom fabricators and serious builders who demand precision-matched flow characteristics, this housing delivers the V-band convenience and A/R sizing needed for a purpose-built turbo system. It’s the right choice when your build requires non-standard rotation direction without compromising on Garrett’s engineering standards.

Specifications

• A/R Ratio: .72
• Rotation: Reverse rotation
• Wastegate Configuration: Externally wastegated
• Inlet/Outlet: V-band entry/exit
• Turbo Family: Garrett G25
• Garrett P/N: 740902-0073

Performance & Application

This turbine housing is purpose-built for custom applications requiring non-standard rotation direction, giving fabricators the flexibility to route exhaust plumbing in configurations that a standard-rotation housing cannot accommodate. The V-band inlet and outlet design streamlines installation and simplifies future serviceability compared to flanged connections. Paired with the externally wastegated setup, this housing is intended for builds where wastegate control is handled independently from the turbine housing itself.
