The BNR ST71 V2 CHRA Update is designed for existing ST71 Version 1 owners looking to improve turbo response, efficiency, and overall performance without replacing the complete turbocharger assembly.

This updated center housing rotating assembly (CHRA) features revised BNR G30-660 aero technology designed to provide improved transient response and increased peak airflow capability over the original Version 1 configuration. (BNR Turbos)

Instead of rebuilding an older or worn CHRA, this upgrade allows customers to refresh and modernize their existing ST71 setup with the latest V2 internals while retaining compatibility with the original turbo system.

The V2 CHRA update is a direct drop-in replacement for existing BNR ST71 Version 1 turbocharger assemblies.
