The Volkswagen Golf R is known for its performance and handling, but for those looking to push the envelope further, upgrading to a BorgWarner S3G turbocharger can provide significant horsepower gains. This guide will walk you through the installation process step-by-step, ensuring you achieve the desired 380 hp output.
Tools and Materials Needed
- BorgWarner S3G Turbocharger
- Turbocharger installation kit
- Socket set (metric)
- Torque wrench
- Screwdrivers (flat and Phillips)
- Wrenches (metric)
- Oil catch pan
- New engine oil and filter
- Intercooler piping kit
- Boost gauge
Preparation Steps
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials needed for the installation. Disconnect the battery to avoid any electrical issues during the process.
Remove the Existing Turbocharger
Begin by removing the engine cover if applicable. Next, disconnect the intake and exhaust pipes from the existing turbocharger. Make sure to keep any bolts and clamps as you will need them for the new installation.
Once the intake and exhaust are disconnected, remove the oil feed and return lines. Be prepared with an oil catch pan to collect any residual oil. Finally, unbolt the turbo from the manifold and carefully remove it from the engine bay.
Install the BorgWarner S3G Turbo
With the old turbo removed, it’s time to install the BorgWarner S3G. Begin by placing the turbo onto the manifold and securing it with the bolts you previously removed. Make sure to torque the bolts to the manufacturer’s specifications to ensure a proper seal.
Next, connect the oil feed and return lines to the new turbo. Ensure that the connections are tight and secure to prevent any oil leaks. After that, attach the intake and exhaust pipes, making sure all clamps are properly tightened.
Intercooler and Piping Installation
Installing the intercooler is crucial for managing the increased heat generated by the new turbo. Begin by removing the front bumper of the Golf R to access the intercooler mounting area.
Next, position the new intercooler in place and secure it using the provided mounting hardware. Connect the intercooler piping to the turbo and intake manifold, ensuring all connections are secure.
Final Steps
Once everything is installed, double-check all connections and ensure there are no loose bolts or clamps. Reconnect the battery and start the engine. Monitor the oil pressure and check for any leaks.
Tuning Your Golf R
After installation, it’s essential to tune your Golf R to optimize performance with the new turbo. This can be done through a professional tuning service or via an ECU remap. Ensure that the boost levels are set correctly to achieve the desired 380 hp without compromising engine safety.
Conclusion
Installing the BorgWarner S3G turbo on your Golf R can significantly enhance its performance. By following this step-by-step guide, you can achieve impressive horsepower gains while ensuring the reliability of your vehicle. Always remember to perform regular maintenance and monitor your vehicle’s performance post-installation.
