  • Boost leaks due to improper fitting
  • Interference with other engine components
  • Electrical connection problems

Issue 1: Inadequate Space for Installation

One of the most common issues when installing the Greddy TD06H-20G turbo is the limited space in the engine bay. This can make it difficult to maneuver the turbo into place.

Solution

To combat this issue, consider the following:

  • Remove any unnecessary components or accessories to create more room.
  • Use a jack to slightly lift the engine if possible, providing more clearance.
  • Have a friend assist you in holding the turbo in place while you secure it.

Issue 2: Incorrect Oil Feed and Drain Line Routing

Proper oil feed and drain line routing is crucial for the turbo’s performance and longevity. Incorrect routing can lead to oil starvation or leaks.

Solution

Follow these steps to ensure correct routing:

  • Refer to the installation manual for the specific routing diagrams.
  • Double-check the connections before starting the engine.
  • Use high-quality hoses and clamps to prevent leaks.

Issue 3: Boost Leaks Due to Improper Fitting

Boost leaks can severely affect performance and are often caused by poor fittings or connections during installation.

Solution

To minimize the risk of boost leaks:

  • Inspect all hoses and connections for tightness and integrity.
  • Use silicone couplers and quality clamps to ensure a secure fit.
  • Consider using a boost leak tester to identify any potential leaks.

Issue 4: Interference with Other Engine Components

The TD06H-20G turbo may interfere with other components such as the intake, exhaust, or even the engine block itself, leading to installation challenges.

Solution

To avoid interference issues:

  • Carefully plan your installation and take measurements of the available space.
  • Consider aftermarket parts that provide better clearance.
  • Consult with experienced installers or forums for advice on common interference issues.

Issue 5: Electrical Connection Problems

Electrical connections for the turbo’s wastegate and other components can be a source of frustration if not properly handled during installation.

Solution

To ensure proper electrical connections:

  • Use solder and heat shrink tubing for secure connections.
  • Label all wires and connections to avoid confusion during reassembly.
  • Test electrical components before finalizing the installation.

Conclusion

Installing the Greddy TD06H-20G turbo on your WRX can be a rewarding upgrade, but it is essential to be aware of common issues that may arise. By following the solutions provided in this article, you can navigate these challenges effectively and enjoy the enhanced performance that this turbo has to offer.
