Now that the stock turbo is out, it’s time to install the Precision Turbo. Follow these steps:
Prepare the New Turbo
Before installation, ensure that all necessary gaskets and fittings are ready. Apply gasket sealant where required.
Install the New Turbo
Position the Precision Turbo in place and secure it with bolts. Make sure it is aligned correctly to avoid any installation issues.
Reconnect the Turbo Lines
Reconnect the oil feed and return lines, as well as the coolant lines. Ensure that all connections are tight to prevent leaks.
Reinstall the Exhaust Manifold
Carefully reinstall the exhaust manifold and secure it with the bolts. Make sure to torque them to the manufacturer’s specifications.
Reattach the Intake Piping
Reconnect the intake piping to the new turbo. Ensure that all clamps are tight and secure.
Final Steps
With the new turbo installed, you need to complete a few final checks before starting the engine.
