Tools and Materials Needed

  • Garrett GT35 Turbo
  • Turbo manifold
  • Wastegate
  • Oil feed line
  • Oil return line
  • Intercooler piping
  • Silicone couplers
  • Clamps
  • Gaskets
  • Wrenches and sockets
  • Torque wrench
  • Boost controller (optional)
  • Engine oil

Preparation Steps

Before starting the installation, it’s important to prepare your workspace and the vehicle. Follow these steps:

  • Park the vehicle on a flat surface and engage the parking brake.
  • Disconnect the battery to prevent any electrical issues.
  • Drain the engine oil and coolant.
  • Remove any components obstructing access to the turbo area, such as the intake manifold or exhaust components.

Removing the Old Turbo

To install the new turbo, you must first remove the old one. Follow these steps:

  • Disconnect the oil feed and return lines from the old turbo.
  • Remove the exhaust manifold bolts and take out the old turbo.
  • Inspect the turbo area for any debris or damage.
  • Clean the mounting surface to ensure a good seal for the new turbo.

Installing the Garrett GT35 Turbo

Now that the old turbo is removed, you can install the Garrett GT35 Turbo. Follow these steps carefully:

  • Place the new turbo on the mounting surface and align it with the exhaust manifold.
  • Secure the turbo with the appropriate bolts, ensuring they are tightened to the manufacturer’s specifications.
  • Reconnect the oil feed line to the turbo, ensuring a tight fit.
  • Attach the oil return line, making sure it is routed correctly to avoid any kinks.

Connecting the Wastegate

The wastegate is an essential component that regulates boost pressure. Here’s how to connect it:

  • Mount the wastegate to the designated area on the turbo or manifold.
  • Connect the actuator rod to the wastegate flap.
  • Attach the vacuum line to the wastegate actuator, if required.

Installing the Intercooler and Piping

To ensure optimal performance, install the intercooler and piping. Follow these steps:

  • Mount the intercooler in the front of the vehicle, ensuring it has adequate airflow.
  • Connect the silicone couplers to the turbo outlet and the intercooler inlet.
  • Route the piping from the intercooler to the throttle body, securing with clamps.

Final Connections and Checks

After installing the turbo and intercooler, complete the final connections:

  • Reconnect all electrical connections that were removed.
  • Fill the engine with fresh oil and coolant.
  • Check all connections for leaks or loose fittings.
  • Reinstall any components that were removed during the process.

Testing the Installation

Before taking your vehicle on the road, it’s crucial to test the installation:

  • Start the engine and let it idle for a few minutes.
  • Check for any oil or coolant leaks around the turbo and connections.
  • Monitor the engine temperature to ensure it is operating within normal limits.
  • Take the vehicle for a short test drive, gradually increasing boost levels.

Troubleshooting Common Issues

If you encounter problems after installation, consider the following troubleshooting tips:

  • Check for boost leaks in the piping and couplers.
  • Inspect the wastegate for proper operation.
  • Verify oil feed and return lines are not kinked or blocked.
  • Ensure all electrical connections are secure.

Conclusion

Installing a Garrett GT35 Turbo on your VG30DETT can greatly enhance your vehicle’s performance. By following this step-by-step guide, you can ensure a successful installation. Always remember to take your time, double-check your work, and enjoy the improvements in your vehicle’s power and efficiency.
