Upgrading your Golf R with a Holset HX35 Hybrid Turbo can significantly enhance its performance. This guide provides a comprehensive step-by-step process to help you install the turbocharger effectively.

Tools and Materials Needed

  • Holset HX35 Hybrid Turbo
  • Turbocharger installation kit
  • Socket set
  • Torque wrench
  • Wrenches
  • Screwdrivers
  • Gasket scraper
  • Engine oil
  • Coolant
  • Shop towels

Preparation Steps

Before starting the installation, ensure you have all the necessary tools and materials at hand. It’s also important to work in a well-ventilated area and allow your vehicle to cool down completely if it has been running.

1. Disconnect the Battery

Begin by disconnecting the negative terminal of the battery to prevent any electrical shorts during the installation process.

2. Drain the Coolant

Next, drain the coolant from the engine to avoid spills when removing the turbo. Locate the drain plug on the radiator and allow the coolant to flow into a suitable container.

Removing the Stock Turbocharger

With the preparations complete, you can now remove the stock turbocharger from your Golf R.

1. Remove the Intake and Exhaust Components

Start by removing the intake piping and any associated components that may obstruct access to the turbocharger. Follow this by detaching the exhaust downpipe.

2. Unbolt the Turbocharger

Once the intake and exhaust components are out of the way, locate the bolts securing the stock turbocharger to the engine. Use the appropriate socket to unbolt the turbo and carefully lift it out of the engine bay.

Installing the Holset HX35 Hybrid Turbo

Now that the stock turbo is removed, it’s time to install the Holset HX35 Hybrid Turbo. Follow these steps closely for a successful installation.

1. Prepare the New Turbocharger

Before installation, inspect the Holset HX35 Hybrid Turbo for any damage. Apply a thin layer of engine oil to the turbo’s oil inlet to ensure proper lubrication during the first start.

2. Position the Turbocharger

Carefully position the new turbocharger into place, aligning it with the mounting points on the engine. Make sure the oil inlet and outlet are correctly oriented.

3. Secure the Turbocharger

Using the original bolts or new ones from the installation kit, secure the turbocharger to the engine. Torque the bolts to the manufacturer’s specifications to ensure a proper seal.

Reconnecting Components

After the turbocharger is securely in place, reconnect all the components that were removed during the disassembly process.

1. Reattach the Exhaust Downpipe

Start by reattaching the exhaust downpipe to the turbo. Ensure that all gaskets are in good condition and replace them if necessary to prevent exhaust leaks.

2. Reconnect the Intake Piping

Next, reconnect the intake piping to the turbocharger. Make sure all clamps are tight and secure to avoid any boost leaks.

Final Steps

With everything reconnected, there are a few final steps to complete before starting your engine.

1. Refill Coolant

Refill the coolant system with the appropriate coolant mixture. Ensure there are no leaks around the turbo and associated components.

2. Reconnect the Battery

Reconnect the negative terminal of the battery. Ensure all connections are secure.

3. Start the Engine

Finally, start the engine and let it idle for a few minutes. Check for any leaks and listen for unusual noises. If everything looks good, take your Golf R for a test drive to experience the enhanced performance of your new Holset HX35 Hybrid Turbo.
