Preparation Steps

Before starting the installation, ensure you have a clean workspace. Gather all tools and materials listed above. It’s also essential to disconnect the vehicle’s battery to prevent any electrical issues during installation.

Remove Existing Turbocharger

Begin by removing the existing turbocharger. This typically involves:

  • Disconnecting the intake and exhaust pipes.
  • Removing the oil feed and return lines.
  • Unbolting the turbo from the manifold.

Install the Turbo Manifold

Once the old turbo is removed, install the new turbo manifold. Make sure to:

  • Use new gaskets to prevent leaks.
  • Torque the bolts to the manufacturer’s specifications.

Installing the EFR 8374 Turbocharger

Next, install the BorgWarner EFR 8374 turbocharger. Follow these steps:

  • Position the turbo on the manifold and align the bolt holes.
  • Secure the turbo with bolts and ensure they are torqued properly.
  • Connect the oil feed and return lines, ensuring they are tight and leak-free.

Installing the EFR 9180 Turbocharger

After the EFR 8374 is installed, proceed to install the EFR 9180 turbocharger:

  • Attach the turbo to the designated mounting location.
  • Use appropriate gaskets to ensure a good seal.
  • Connect the necessary oil lines as done with the EFR 8374.

Connecting the Intercooler and Piping

With both turbochargers installed, it’s time to connect the intercooler and piping:

  • Install the intercooler in the front of the vehicle.
  • Connect the piping from the turbos to the intercooler using silicone couplers.
  • Ensure all clamps are tightened securely.

Install the Boost Controller

The boost controller is crucial for managing the performance of the compound turbo system. Follow these steps:

  • Mount the boost controller in a convenient location.
  • Connect necessary vacuum lines to the wastegates on both turbos.
  • Configure the boost settings according to your performance goals.

Final Checks and Testing

Before starting the engine, perform the following final checks:

  • Double-check all connections for tightness.
  • Ensure there are no leaks in oil or coolant lines.
  • Reconnect the battery and prepare for testing.

Starting the Engine

With everything in place, start the engine and monitor for any unusual sounds or leaks. Allow the engine to reach operating temperature while checking:

  • Oil pressure readings.
  • Temperature levels of the turbos.
  • Boost levels through the controller.

Tuning and Adjustments

After the initial startup, it’s essential to tune the vehicle for optimal performance. Consider the following:

  • Consult a professional tuner for best results.
  • Adjust fuel maps and ignition timing as necessary.
  • Test drive the vehicle under different conditions.

Conclusion

Installing a BorgWarner EFR 8374 and 9180 compound turbo system can be a rewarding project that enhances your vehicle’s performance. Following this guide will help ensure a successful installation and tuning process, leading to an exhilarating driving experience.
