The HKS GT4950-BB is a high-performance ball bearing turbocharger designed for enthusiasts targeting 500+ horsepower builds. This turbo is part of HKS's GT Turbine Series, developed in collaboration with Garrett to deliver improved airflow and efficiency even at high boost levels. The GT4950-BB features an A/R 0.72 exhaust housing with V-Band inlet and outlet flanges.

Key Features:

• Ball bearing center housing rotating assembly (CHRA) for quick spool and reduced turbo lag
• Compressor wheel: 54mm inlet / 67mm outlet diameter with 65 trim
• Turbine wheel: 49mm outlet / 54mm outer diameter with 84 trim
• 76.2mm compressor housing intake diameter with 0.70 A/R
• Machined aluminum ported shroud with bell mouth design combining T51R type recirculation channel for anti-surge protection and smooth airflow

Developed as an upgrade for the previous GTIII-RS model, the GT4950-BB is optimized for RB26 (2.8L) twin turbo setups, SR20 (2.0L), EJ20, G16E, and VR38 applications. This turbocharger can be used as a direct upgrade and replacement for original T51R, TO4Z, and earlier V-Band type GT turbine kits. The 0.72 A/R exhaust housing provides excellent response characteristics while maintaining strong top-end power delivery for serious street, drift, drag racing, and track applications.
