Preparation Steps
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all necessary tools and materials. Wearing safety glasses is recommended throughout the process.
Disconnect the Battery
To prevent any electrical issues, disconnect the negative terminal of the battery before beginning the installation.
Remove the Engine Cover
Using a socket set, remove the bolts securing the engine cover. Carefully lift the cover off and set it aside.
Removing the Stock Turbocharger
Drain the Coolant
To avoid spills, drain the coolant from the system. Locate the drain plug on the radiator and allow the coolant to flow into a suitable container.
Remove Intake and Exhaust Components
Begin by removing the intake piping connected to the stock turbo. Next, disconnect the exhaust components, including the downpipe and any associated heat shields.
Disconnect Oil and Coolant Lines
Carefully disconnect the oil feed and return lines as well as the coolant lines from the stock turbocharger. Be prepared for some oil and coolant spillage.
Remove the Stock Turbocharger
Unbolt the stock turbocharger from the manifold and lift it out of the engine bay. Set it aside for comparison with the new SP Turbocharger.
Installing the SP Turbocharger
Prepare the New Turbocharger
Before installation, ensure that the new SP Turbocharger is clean and free from debris. Inspect all components included in the kit.
Install the SP Turbocharger
Position the new turbocharger onto the manifold. Secure it using the provided bolts, ensuring they are tightened to the manufacturer’s specifications using a torque wrench.
Reconnect Oil and Coolant Lines
Reconnect the oil feed and return lines, making sure they are secure. Reattach the coolant lines, ensuring there are no leaks.
Install Intake and Exhaust Components
Reinstall the intake piping and the downpipe. Ensure all connections are tight and secure to prevent boost leaks.
Final Steps
Reconnect the Battery
Once everything is reassembled, reconnect the negative terminal of the battery.
Refill Coolant
Refill the coolant system with the appropriate coolant mixture. Check for any leaks around the turbo and coolant lines.
Start the Engine
Start the engine and allow it to idle. Monitor for any unusual noises or leaks. If everything appears normal, take the vehicle for a short test drive.
