TTE777 6660 2.5TFSI CZGB / CEPA UPGRADE TURBOCHARGER

The TTE777 is an upgraded performance turbocharger based on the original RS3 8V.2 / TTRS 8S DAZA and DNWA units. At TheTurboEngineers, we meticulously rework these turbos to deliver a class-leading hybrid performance solution for the older-generation CEPA, CEPB, and CZGB engines.

Key Performance Upgrades

  • Compressor Wheel: The original wheel is replaced with a precision-milled TTE aluminum wheel featuring advanced 7+7 blade geometry, providing significantly higher airflow and power output than even the TTE700 wheel.

  • Exhaust Turbine: The stock turbine is upgraded to a lightweight 9-blade TTE-designed turbine, engineered for lower exhaust backpressure to maximize performance.

  • Bearing System: A TTE motorsport-grade bearing system is installed for enhanced durability under high-performance conditions.

Boost response is carefully optimized to ensure immediate and consistent power delivery, making the TTE777 a highly responsive upgrade.

Exhaust Manifold Optimization

With the TTE777 Stage upgrade, the exhaust manifold is CNC-ported to perfectly align with the OEM gasket at the head flange. Each runner is smoothed to increase gas velocity, efficiently feeding the larger 9-blade turbine and enabling the upgraded compressor to perform at its full potential. Additional turbine-side modifications further enhance gas flow for maximum performance gains.

OEM Integration & Thermal Management

When ordering a new unit, we use the latest generation of BorgWarner turbochargers as a base. Each comes with Audi-spec thermal heat isolation shielding on the exhaust manifold and turbine housing to reduce engine bay temperatures, improve safety, and maintain peak performance.

Precision Balance & Reliability

Longevity and performance are critical for every TTE upgrade. Each turbocharger undergoes meticulous balancing to ensure ultimate equilibrium:

  1. Component Balancing: Individual parts are balanced at low speeds up to 2,800 RPM in multiple planes.

  2. CHRA Dynamic Balancing: After assembly, the CHRA is dynamically balanced at application-specific speeds up to 250,000 RPM using our in-house VSR machine—well beyond OEM standards.

  3. Documentation: Every turbo is supplied with a serial-numbered balance test report for complete verification.

This precision engineering not only improves reliability and efficiency but also enhances acoustics and overall refinement.
