Preparation
Before beginning the installation, ensure that you have all the necessary tools and materials ready. It is also important to work in a well-ventilated area and wear safety glasses to protect your eyes.
Disconnect the Battery
Start by disconnecting the negative terminal of the battery to prevent any electrical shorts during the installation process.
Remove the Engine Cover
Next, remove the engine cover by unscrewing the bolts securing it in place. This will give you access to the turbocharger and surrounding components.
Removing the Stock Turbocharger
To install the Garrett GTX3076R, the stock turbocharger must be removed first. Follow these steps to safely detach it.
Remove the Exhaust Manifold
Begin by removing the exhaust manifold that connects to the stock turbo. Use the socket set to unscrew the bolts, and carefully lift the manifold away from the engine.
Disconnect the Wastegate Actuator
Next, disconnect the wastegate actuator from the stock turbocharger. This may require a wrench to loosen the connection.
Remove the Turbocharger
With the exhaust manifold removed, you can now take out the stock turbocharger. Unscrew any remaining bolts and carefully pull the turbo out of its housing.
Installing the Garrett GTX3076R
Now that the stock turbo has been removed, it’s time to install the new Garrett GTX3076R turbocharger.
Install the New Turbocharger
Position the Garrett GTX3076R into place and secure it with the provided bolts. Make sure to torque them to the manufacturer’s specifications to ensure a proper fit.
Reconnect the Wastegate Actuator
Reconnect the wastegate actuator to the new turbocharger, ensuring that it is secured tightly to prevent any boost leaks.
Reconnect the Exhaust Manifold
Reattach the exhaust manifold to the Garrett GTX3076R. Tighten the bolts securely and ensure that there are no gaps or leaks.
Connecting Oil and Coolant Lines
Proper oil and coolant connections are essential for the turbocharger’s performance and longevity.
Install Oil Feed Line
Attach the oil feed line to the new turbocharger. Make sure to use new seals to prevent any oil leaks.
Install Oil Return Line
Connect the oil return line, ensuring it is routed correctly to avoid kinks and potential blockages.
Connect Coolant Lines
Finally, connect the coolant lines to the turbocharger. Again, ensure that all connections are secure to prevent leaks.
Final Steps
After the turbocharger is installed and all lines are connected, it’s time to reassemble any components that were removed during the process.
Reinstall the Engine Cover
Put the engine cover back in place and secure it with the bolts that were previously removed.
Reconnect the Battery
Reconnect the negative terminal of the battery, ensuring a secure connection.
Testing the Installation
With everything reassembled, it’s crucial to test the installation before taking the vehicle for a drive.
Check for Leaks
Start the engine and check for any signs of oil or coolant leaks around the turbocharger and connections.
Monitor Performance
Take the vehicle for a test drive and monitor the performance. Ensure that the turbo is functioning correctly and that there are no unusual sounds or issues.
Conclusion
Upgrading to the Garrett GTX3076R turbocharger can significantly enhance the performance of your A90 Supra. By following this installation guide, you can ensure a successful upgrade that will bring your driving experience to a whole new level.
