CHRA – Garrett GT3082R (aka GT30/40R)

The Garrett GT3082R CHRA is a proven ball bearing core upgrade built for enthusiasts who demand a broader powerband without sacrificing spool. Pairing the larger GT35R compressor wheel with the full-size GT30-series turbine, this configuration is the go-to choice for builders looking to bridge the gap between smaller GT30/40R turbos and true big-frame power. It’s an ideal core for street cars and mild competition builds that need real top-end capability while retaining a responsive, drivable low-end.

Specifications

• Compressor Wheel: 82mm
• Compressor Trim: 56 trim
• Turbine Wheel: 60mm full-size
• Bearing Type: Twin-ball bearing
• HP Capacity: Supports up to 550+ hp
• Garrett P/N: 700177-5014S
• Also Known As: GT30/40R, GT3082R

Performance & Application

This CHRA is engineered for builders stepping up from smaller GT30/40R configurations who need additional top-end airflow without giving up the twin-ball bearing responsiveness that defines the platform. The 82mm 56 trim compressor wheel, sourced from the GT35R, extends the power ceiling while the full-size 60mm turbine wheel maintains strong spool characteristics. This makes it well suited to street builds and mild competition applications where a broad, usable powerband matters as much as outright peak output. It represents a direct upgrade path for owners looking to extract more from their existing GT30/40R-based setup.

Compatibility & Fitment

• Compatible with turbo P/N 700177-5014S
