Performance & Application
This Garrett T3/T4E ball bearing turbo is engineered for builders targeting up to 450 horsepower with the added durability and spool advantage of a dual ball bearing center section. The 57 trim compressor and Stage III turbine wheel combination is tuned for strong mid-range response while maintaining top-end flow for aggressive power builds. Selectable A/R ratios allow tuners to dial in the exact balance of spool-up and top-end power for their specific application. Optional alternate turbine housings, including Ford-style 5 bolt discharge and Cosworth-style configurations, provide added flexibility for custom exhaust manifold setups.
