CTS Turbo BMW B58 Gen 1 Stage 2+ Hybrid Turbo - CTS-TR-1057

Maximize the performance of your BMW B58 Gen 1 engine with the CTS Turbo Stage 2+ Hybrid Turbo. Designed for enthusiasts seeking substantial horsepower and torque gains, this hybrid turbo offers increased airflow, improved efficiency, and superior reliability while maintaining OEM fitment. Engineered to support 700+ whp with the proper supporting modifications, it delivers remarkable performance without sacrificing drivability.

This upgraded turbo features a billet compressor wheel (62/82mm) and a high-flow turbine wheel (62/68mm) for enhanced spool characteristics, faster throttle response, and optimized exhaust flow. The larger wheels allow for greater air volume, making it ideal for higher boost pressures, ethanol blends, and custom tuning.

For seamless installation, the package includes a high-flow turbo inlet pipe, ensuring optimized airflow to the intake system. Simply remove the factory turbocharger, transfer the wastegate actuator, and reinstall. The provided hardware and modified heat shield make the actuator installation quick and straightforward.

For proper operation, the wastegate actuator must be calibrated via ISTA+ after installation.
