Installing a Precision 46mm Wastegate on a Honda Civic Type R: Step-by-step to Higher Boost

The Honda Civic Type R is known for its impressive performance and tuning potential. One of the key components that can enhance its capabilities is the wastegate. In this article, we will guide you through the process of installing a Precision 46mm wastegate on your Honda Civic Type R, step by step, to achieve higher boost levels and improved performance.

Tools and Materials Needed

  • Precision 46mm wastegate
  • Wrenches and sockets (10mm, 12mm, 14mm)
  • Torque wrench
  • Silicone hose
  • V-band clamps
  • Boost controller (optional)
  • Vacuum line
  • Heat-resistant gasket
  • Safety glasses and gloves

Preparation Steps

Before starting the installation, make sure your vehicle is parked on a flat surface and the engine is cool. Gather all the tools and materials listed above to ensure a smooth installation process.

Disconnect the Battery

For safety, disconnect the negative terminal of the battery to prevent any electrical shorts during the installation.

Remove the Engine Cover

Using a socket wrench, remove the bolts securing the engine cover. Carefully lift off the cover and set it aside.

Removing the Stock Wastegate

Next, we will remove the stock wastegate. This process involves disconnecting various components to make way for the new wastegate.

Locate the Stock Wastegate

The stock wastegate is typically located on the turbocharger. Refer to your vehicle’s manual if you’re having trouble locating it.

Disconnect the Vacuum Line

Carefully disconnect the vacuum line from the stock wastegate. You may need to use pliers to gently remove it if it is tight.

Unbolt the Wastegate

Using the appropriate socket, unbolt the stock wastegate from the turbocharger. Be sure to keep track of the bolts for reuse.

Installing the Precision 46mm Wastegate

Now that the stock wastegate is removed, it’s time to install the Precision 46mm wastegate.

Prepare the New Wastegate

Before installation, ensure that the Precision wastegate is equipped with a heat-resistant gasket for a proper seal.

Mount the Wastegate

Align the Precision 46mm wastegate with the mounting holes on the turbocharger. Insert the bolts and hand-tighten them to hold the wastegate in place.

Torque the Bolts

Using a torque wrench, tighten the bolts to the manufacturer’s specified torque settings. This ensures a secure fit and prevents leaks.

Reconnect the Vacuum Line

Reconnect the vacuum line to the Precision wastegate. Ensure it is securely attached to avoid any boost control issues.

Final Steps

With the new wastegate installed, there are a few final steps to complete the installation process.

Reinstall the Engine Cover

Place the engine cover back on and secure it with the bolts you removed earlier.

Reconnect the Battery

Reconnect the negative terminal of the battery, ensuring it is tightly secured.

Start the Engine

Start the engine and let it idle for a few minutes. Check for any leaks around the wastegate area.

Tuning for Higher Boost

After installing the Precision 46mm wastegate, tuning may be required to achieve optimal performance. Here are some tips:

  • Use a quality boost controller to manage boost levels effectively.
  • Monitor air-fuel ratios to ensure your engine runs safely.
  • Consider a professional tune for best results.

Conclusion

Installing a Precision 46mm wastegate on your Honda Civic Type R can significantly enhance its performance by allowing for higher boost levels. Following this step-by-step guide will help ensure a successful installation and tuning process. Enjoy the improved power and responsiveness of your vehicle!
