The MHI TD06H-20G turbocharger is a popular upgrade for the Mitsubishi Lancer Evolution 9 (Evo 9), providing significant performance enhancements. However, installing this turbo can come with its own set of challenges. In this article, we will explore common installation challenges and provide solutions to ensure a smooth installation process.

Common Installation Challenges

  • Turbo fitment issues
  • Oil feed and drain line complications
  • Intercooler piping alignment
  • Boost control solenoid setup
  • Electrical connections

1. Turbo Fitment Issues

One of the most common challenges during the installation of the MHI TD06H-20G turbo on the Evo 9 is ensuring proper fitment. The turbo must align correctly with the existing manifold and exhaust system.

Solution

To address fitment issues, consider the following:

  • Check the compatibility of the turbo with the Evo 9’s manifold.
  • Use a turbo inlet adapter if necessary.
  • Ensure that all mounting bolts are tightened to the manufacturer’s specifications.

2. Oil Feed and Drain Line Complications

Proper oil feed and drain lines are crucial for the longevity of the turbo. Incorrect installation can lead to oil starvation or leaks.

Solution

Follow these steps to avoid complications:

  • Use high-quality AN fittings and lines for the oil feed and drain.
  • Ensure that the oil drain line has a proper downward slope to prevent pooling.
  • Double-check all connections for leaks before starting the engine.

3. Intercooler Piping Alignment

When upgrading to the TD06H-20G turbo, the intercooler piping may need to be adjusted or replaced to fit the new turbo setup.

Solution

To ensure proper alignment:

  • Inspect the existing intercooler piping for compatibility.
  • Consider using custom piping or a silicone coupler for better fitment.
  • Secure all connections with proper clamps to prevent boost leaks.

4. Boost Control Solenoid Setup

The boost control solenoid may require reconfiguration to work effectively with the new turbo setup.

Solution

To set up the boost control solenoid correctly:

  • Follow the manufacturer’s instructions for wiring and placement.
  • Test the solenoid operation before finalizing the installation.
  • Adjust the boost levels as necessary using a tuning device.

5. Electrical Connections

Electrical connections can often be overlooked during installation, leading to performance issues or failure to operate.

Solution

Ensure all electrical connections are secure:

  • Check all wiring harnesses for damage or wear.
  • Use dielectric grease on connectors to prevent corrosion.
  • Verify that all sensors are functioning properly after installation.

Conclusion

Installing the MHI TD06H-20G turbo on the Evo 9 can present several challenges, but with proper preparation and attention to detail, these issues can be effectively resolved. By following the solutions outlined in this article, you can enjoy the enhanced performance of your Evo 9 with confidence.
