Performance & Application
This T3/60-1 journal bearing turbocharger is engineered for builds targeting up to 550 horsepower, making it a strong fit for performance engines that need a reliable step up from stock or smaller turbo frames. The Stage III turbine wheel combined with the 60-1 compressor wheel delivers strong airflow through the T04S compressor housing, while the T31 four-bolt turbine housing keeps exhaust-side packaging compact and proven. Because this is an oil-cooled only design, it’s best suited for builders who have an appropriate oiling setup and are not looking for a watercooled bearing system. The available A/R ratio options allow tuners to dial in spool characteristics versus top-end power to match their specific power goals and driving style.
