Preparation
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to prevent any electrical issues during the installation.
Step 1: Remove the Stock Turbocharger
Begin by removing the intake system. Disconnect the air intake duct and the mass airflow sensor. Next, detach the intercooler by removing the clamps and bolts securing it in place.
Now, access the stock turbocharger. Remove the heat shield and disconnect the oil feed line, oil drain line, and coolant lines. Unbolt the turbo from the exhaust manifold and carefully lift it out.
Step 2: Prepare the New Turbocharger
Before installing the TD06H-20G turbo, ensure that all gaskets are in good condition. Use a gasket scraper to remove any old gasket material from the mounting surfaces. Install the new gaskets on the turbo and the exhaust manifold.
Step 3: Install the TD06H-20G Turbocharger
Carefully position the TD06H-20G turbocharger onto the exhaust manifold. Make sure the mounting holes align properly. Secure the turbo with the bolts and use a torque wrench to tighten them to the manufacturer’s specifications.
Step 4: Connect Oil and Coolant Lines
Reconnect the oil feed line and oil drain line to the turbocharger. Ensure there are no leaks by checking the fittings. Next, connect the coolant lines, making sure they are securely fastened.
Step 5: Reinstall the Intercooler and Intake System
Reattach the intercooler by securing it with the clamps and bolts. Then, reconnect the air intake duct and the mass airflow sensor. Ensure all connections are tight and secure.
Step 6: Reconnect the Battery and Test
Once everything is reassembled, reconnect the battery. Start the engine and let it idle for a few minutes. Check for any leaks around the turbo and lines. If everything looks good, take the car for a test drive to ensure the turbo is functioning properly.
Conclusion
Installing the TD06H-20G turbocharger on your Subaru WRX can be a rewarding project that enhances your vehicle’s performance. By following these steps carefully, you can ensure a successful installation. Always remember to consult your vehicle’s manual and follow safety precautions during the process.
