The Honda H22 engine is a popular choice for enthusiasts looking to boost their vehicle’s performance. In this guide, we will cover the installation of the BorgWarner EFR 6758 turbocharger, which is known for its reliability and power output. Follow these steps to ensure a successful installation and get the most out of your H22 turbo build.

Tools and Materials Needed

  • BorgWarner EFR 6758 turbocharger
  • Turbo manifold
  • Oil feed and return lines
  • Intercooler and piping
  • Wastegate
  • Boost controller
  • Fuel injectors
  • ECU tuning software
  • Basic hand tools (sockets, wrenches, etc.)
  • Torque wrench

Preparation Steps

Before starting the installation, it’s crucial to prepare your workspace and gather all necessary tools and materials. Ensure your vehicle is parked on a level surface and that you have sufficient lighting. Disconnect the battery to prevent any electrical issues during the installation process.

Remove Existing Components

Begin by removing the stock intake manifold, exhaust manifold, and any other components blocking access to the engine bay. This will create space for the new turbo setup. Take care to label and store bolts and parts to make reassembly easier.

Installing the Turbo Manifold

Once you have cleared the area, it’s time to install the turbo manifold. Ensure that the manifold is compatible with the EFR 6758 turbocharger.

  • Align the manifold with the engine block.
  • Insert and hand-tighten the bolts to secure the manifold.
  • Use a torque wrench to tighten the bolts to the manufacturer’s specifications.

Mounting the BorgWarner EFR 6758 Turbocharger

With the manifold secured, you can now mount the BorgWarner EFR 6758 turbocharger. Ensure that the turbo is oriented correctly for optimal performance.

  • Position the turbocharger onto the manifold.
  • Secure it using the provided hardware.
  • Double-check the alignment of the turbo with the exhaust and intake piping.

Connecting Oil Lines

Proper oil flow is essential for turbo performance and longevity. Connect the oil feed and return lines to the turbocharger.

  • Attach the oil feed line to the top of the turbo.
  • Connect the oil return line to the bottom of the turbo.
  • Ensure all fittings are tight and leak-free.

Installing the Intercooler

After the turbo is secured and the oil lines are connected, the next step is to install the intercooler. This component helps cool the air entering the engine, increasing performance.

  • Mount the intercooler in the front of the vehicle.
  • Connect the piping from the turbo to the intercooler.
  • Ensure all connections are secure and leak-free.

Wastegate and Boost Controller Installation

The wastegate is crucial for controlling boost levels. Install the wastegate according to the manufacturer’s instructions.

  • Attach the wastegate to the turbocharger.
  • Connect the boost controller to the wastegate.
  • Set the desired boost levels according to your tuning needs.

Fuel System Upgrades

To support the increased power from the turbocharger, upgrading the fuel system is necessary. This typically involves installing larger fuel injectors and possibly a high-flow fuel pump.

  • Remove the stock fuel injectors.
  • Install the new, larger fuel injectors.
  • Ensure that the fuel lines are secure and leak-free.

ECU Tuning

After all components are installed, it’s essential to tune the ECU to optimize performance. Use ECU tuning software to adjust fuel maps and ignition timing.

  • Connect the ECU to your tuning software.
  • Upload the necessary maps for turbo operation.
  • Test the vehicle to ensure everything is functioning correctly.

Final Checks and Testing

Once everything is installed and tuned, perform a series of checks before taking the vehicle for a test drive.

  • Check for any oil or coolant leaks.
  • Ensure all connections are tight and secure.
  • Start the engine and monitor for any unusual noises.

Conclusion

Installing a BorgWarner EFR 6758 turbocharger on an H22 engine can significantly enhance performance and reliability. By following this guide, you can ensure a successful installation and enjoy the benefits of turbocharging your Honda.
