Description
The Comp Turbo CT3RX-5858 Triplex Ceramic Ball Bearing Oil-Less Water-Cooled Turbocharger is engineered to deliver exceptional performance in 400 to 775 horsepower applications. By eliminating traditional oil supply lines while retaining efficient water cooling, this turbocharger simplifies installation while providing excellent thermal control for demanding street and track environments.
At the heart of the CT3RX-5858 is Comp Turbo’s patented Triplex Ceramic ball bearing system, designed to deliver ultra-smooth operation, faster spool response, and long-term durability. The lightweight billet aluminum center section reduces overall mass while maintaining structural strength, making this turbo ideal for engine bay, mid-mount, or remote-mount turbo system configurations.
This unit features a 58mm CTRX ultra-slim hub billet aluminum compressor wheel paired with a 58mm high-flow 9-blade turbine wheel, offering balanced airflow efficiency and responsive boost delivery across a wide RPM range. The CT3RX-5858 supports horizontal and vertical mounting and is available with T3 or V-band inlet turbine housings, allowing flexibility for custom turbocharger installations.
