Preparation
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Gather all the tools and materials listed above.
Disconnect the Battery
Begin by disconnecting the negative terminal of the battery to prevent any electrical shorts during the installation process.
Remove the Existing Turbocharger (if applicable)
If your Celica GT-Four has an existing turbocharger, you will need to remove it. Start by disconnecting the intake and exhaust pipes connected to the turbo. Then, unbolt the turbo from the manifold and carefully lift it out of the engine bay.
Installing the Garrett GT28 Turbo
Attach the Turbocharger to the Manifold
Position the Garrett GT28 Turbo onto the turbocharger manifold. Ensure that the mounting holes align properly. Use the provided bolts to secure the turbo to the manifold, tightening them to the manufacturer’s specifications with a torque wrench.
Install the Wastegate
Attach the wastegate to the turbocharger according to the manufacturer’s instructions. Ensure that it is securely fastened and that the wastegate actuator is connected properly.
Connect Oil Feed and Return Lines
Install the oil feed line to the turbocharger, ensuring it is tight and leak-free. Then, connect the oil return line to the appropriate location on the engine. Make sure all connections are secure to prevent oil leaks.
Install the Intercooler
Position the intercooler in front of the radiator. Use the mounting brackets to secure it in place. Connect the silicone couplers to the turbo outlet and the intercooler inlet, ensuring a tight fit with clamps.
Connect the Intake and Exhaust
Reconnect the intake pipe to the turbocharger. Ensure all connections are tight. Then, connect the exhaust pipe to the turbo outlet, making sure there are no leaks.
Final Steps
Check All Connections
Before starting the engine, double-check all connections, including oil lines, intake, and exhaust. Make sure everything is secure and properly fitted.
Reconnect the Battery
Reconnect the negative terminal of the battery. Ensure that it is tight and secure.
Start the Engine
Start the engine and let it idle for a few minutes. Check for any oil or coolant leaks. Listen for any unusual noises that may indicate a problem.
Tuning Your Celica GT-Four
After installation, it is essential to tune your Celica GT-Four to ensure optimal performance with the new turbocharger. Consider the following:
- Adjust fuel maps to accommodate increased airflow.
- Check and adjust ignition timing.
- Monitor boost levels and adjust wastegate settings if necessary.
Conclusion
Installing a Garrett GT28 Turbo on your Celica GT-Four can significantly boost its performance. By following this step-by-step guide, you can ensure a successful installation. Always remember to check for leaks and tune your vehicle for the best results.
