Performance & Application
Built around the Garrett G25 platform, this turbine housing is designed for standard rotation applications requiring internal wastegate control. The .49 A/R sizing paired with a T25 entry supports a balanced blend of spool characteristics suited to G25-based turbocharger builds. Its V-band exit simplifies downpipe integration for modern turbo system layouts. This housing is intended for builders standardizing on the G-Series architecture who require a direct-fit, internally gated solution.
