by

The RB26 engine, known for its performance and tuning potential, is a popular choice among car enthusiasts. This guide will take you through the step-by-step process of upgrading your RB26 with a TD06H turbo and an upgraded intercooler to achieve an impressive 550 horsepower.

Understanding the RB26 Engine

The RB26DETT is a 2.6-liter inline-six engine produced by Nissan. It features a twin-turbo setup that provides a solid foundation for performance upgrades. To reach 550 hp, several modifications are necessary.

Parts Required for the Upgrade

  • TD06H Turbocharger
  • Upgraded Intercooler
  • High-flow Fuel Injectors
  • Aftermarket Fuel Pump
  • ECU Tune
  • Upgraded Exhaust System
  • Boost Controller
  • Silicone Hoses and Clamps

Step 1: Removing the Stock Turbo

Begin by safely lifting the vehicle and removing the front bumper for easier access. Disconnect the battery and drain the coolant. Remove the stock turbocharger by following these steps:

  • Disconnect the intake and exhaust pipes.
  • Unplug any electrical connections.
  • Remove the oil and coolant lines.
  • Unbolt the turbo from the manifold.

Step 2: Installing the TD06H Turbo

With the stock turbo removed, it’s time to install the TD06H turbocharger. Follow these steps:

  • Position the TD06H turbo onto the manifold.
  • Secure it with the appropriate bolts.
  • Reconnect the oil and coolant lines.
  • Attach the intake and exhaust pipes.

Step 3: Upgrading the Intercooler

An upgraded intercooler is essential for maintaining lower intake temperatures and maximizing performance. To install the new intercooler:

  • Remove the old intercooler and piping.
  • Position the new intercooler in place.
  • Connect the silicone hoses and clamps securely.
  • Ensure all connections are tight to prevent leaks.

Step 4: Fuel System Upgrades

To support the increased power, upgrading the fuel system is crucial. This includes:

  • Installing high-flow fuel injectors.
  • Replacing the stock fuel pump with a higher capacity unit.
  • Checking fuel lines for any leaks or restrictions.

Step 5: ECU Tuning

Once all hardware upgrades are complete, the final step is to tune the ECU. This is critical for optimizing performance and ensuring the engine runs smoothly with the new components. Consider these options:

  • Using a standalone ECU for full control.
  • Visiting a professional tuner for custom mapping.
  • Monitoring air-fuel ratios and boost levels during the tuning process.

Step 6: Final Checks and Testing

Before taking your upgraded RB26 for a spin, perform these final checks:

  • Inspect all connections and fittings for leaks.
  • Check oil levels and coolant levels.
  • Start the engine and monitor for any unusual sounds.
  • Conduct a test drive to ensure everything is functioning correctly.

Conclusion

Upgrading your RB26 to achieve 550 hp with a TD06H turbo and an upgraded intercooler is a rewarding project that enhances performance significantly. With careful planning and execution, you can enjoy the thrill of driving a powerful, well-tuned machine.
