Performance & Application
Built around Garrett’s GTW Series architecture, this 67mm ball bearing turbo is engineered as a high-performance alternative to the widely used 6766 size turbocharger. The T3 turbine inlet paired with a GT 3″ V-Band outlet and 1.06 A/R turbine housing is configured to support strong mid-range response while still delivering the flow capacity needed for high-output builds. Its combination of compressor and turbine wheel geometry is designed to balance quick spool characteristics with the top-end power potential enthusiasts expect from a serious performance turbocharger. This turbo suits builders looking to push well into the high-horsepower range while retaining drivability.
