This CHRA is a special-spec center housing rotating assembly built on the Garrett GT3076R platform, engineered for enthusiasts who need a precise, factory-matched core replacement rather than a generic substitute. Its trimmed turbine and compressor wheel combination targets a specific performance window, making it the right choice for builders who already know their exact turbo configuration and demand an exact-match rebuild. This is a ball bearing core designed for smooth, efficient boost delivery and confident spool characteristics.

Specifications

• Compressor Wheel: 76mm, 48 trim
• Turbine Wheel: 56.5mm, 84 trim (trimmed down)
• Bearing Type: Ball bearing
• Also Known As: Garrett GT3076R-WG-C10 (special)

Performance & Application

This CHRA is purpose-built as a special variant of the proven GT3076R platform, using a trimmed 84 trim turbine wheel paired with a 48 trim compressor wheel to shape its power delivery. The ball bearing design supports efficient boost production across mid-range RPM bands, with aerodynamic flow characteristics tuned for enhanced spool response. It’s suited for builders replacing or upgrading the core in a specific compatible turbocharger application rather than for general-purpose turbo assembly. Enthusiasts running the corresponding turbo housing will benefit from a rotating assembly matched precisely to that application’s performance intent
