Description
Comp Turbo CT2RX-4647 triplex ceramic ball bearing turbocharger. Oil lubricated, built for street and track, and sold with the turbine housing — this is a complete turbo, not a cartridge. The ball bearing center section spools faster and runs less friction than a journal bearing, which is the point of the CT2RX line: boost with minimal lag on a small-displacement engine. The 4647 is the smallest of the three — 500 HP max, sized for 1.4 to 2.5 liters.
- Patented triplex ceramic ball bearing system — oil lubricated
- Lightweight billet aluminum center section
- CTRX billet aluminum ultra-slim hub 46 mm compressor wheel
- Inconel 713C 9-blade 47 mm turbine wheel
- T2 internally wastegated (actuator included) or stainless V-band turbine housing — pick from the drop-down
- Fully rebuildable and upgradeable
- 2-year Comp Turbo warranty on materials and workmanship
