Step-by-Step Installation Guide
Step 1: Remove the Stock Turbo
Start by disconnecting the battery. Next, remove the engine cover and intake system to access the turbocharger. Disconnect the exhaust and coolant lines from the stock turbo, followed by the electrical connectors. Finally, unbolt the turbo from the manifold and remove it from the engine bay.
Step 2: Prepare the Pure Turbo
Take the Pure Turbo out of the box and inspect it for any damage. Install the new gaskets onto the turbocharger. This step is crucial to ensure a proper seal and prevent any leaks once the turbo is installed.
Step 3: Install the Pure Turbo
Position the Pure Turbo in the engine bay, aligning it with the manifold. Secure it in place using the bolts you removed earlier. Reattach the exhaust and coolant lines, ensuring everything is tightened to the manufacturer’s specifications.
Step 4: Reconnect Electrical Components
Reconnect all electrical connectors that were disconnected during the removal of the stock turbo. Double-check to ensure that each connection is secure and properly seated.
Step 5: Reinstall Intake and Engine Cover
Once the turbo is installed, reinstall the intake system and engine cover. Ensure that all clamps and bolts are tightened to prevent any air leaks.
Step 6: Reconnect the Battery and Check for Leaks
Reconnect the battery and start the engine. Allow it to idle for a few minutes while checking for any leaks around the turbo and associated lines. If everything looks good, you’re ready to hit the road!
Tuning After Installation
After installing the Pure Turbo, tuning is essential to maximize performance and ensure the engine runs efficiently. It is recommended to visit a professional tuner who is familiar with the B58 engine and can provide a custom tune to take full advantage of the new turbocharger.
