Installing BRZ headers can significantly enhance the performance of your vehicle. This guide will walk you through the step-by-step process for installing Perrin and Manley headers, ensuring you achieve optimal results.
Tools and Materials Needed
- Socket set
- Torque wrench
- Ratchet and extensions
- Jack and jack stands
- Header gaskets
- Anti-seize lubricant
- Safety glasses
- Gloves
Before beginning the installation, gather all necessary tools and materials. This will help streamline the process and minimize interruptions.
Preparation
Start by ensuring your vehicle is parked on a flat surface. Engage the parking brake and disconnect the negative battery terminal to prevent any electrical issues during installation.
Lift the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. This will provide you with enough space to work comfortably under the car.
Removing the Old Headers
To install the new headers, you must first remove the old ones. Follow these steps carefully:
- Remove the intake manifold if necessary for better access.
- Disconnect any sensors or wiring harnesses connected to the headers.
- Unbolt the exhaust manifold from the engine block.
- Carefully remove the old headers from the vehicle.
Make sure to keep track of all bolts and components removed during this process, as you will need them for the installation of the new headers.
Installing the New Headers
Now that the old headers are removed, it’s time to install the new Perrin or Manley headers. Follow these steps for a successful installation:
- Clean the surface of the engine block where the headers will mount.
- Apply a thin layer of anti-seize lubricant to the bolts.
- Position the new headers in place and align them with the bolt holes.
- Hand-tighten the bolts to secure the headers temporarily.
Ensure the headers are aligned correctly before fully tightening the bolts.
Tightening the Bolts
Using a torque wrench, tighten the bolts to the manufacturer’s specifications. This step is crucial to prevent any leaks or damage to the headers.
Reconnecting Components
After securing the new headers, it’s time to reconnect all previously removed components:
- Reattach the exhaust manifold to the engine block.
- Reconnect any sensors or wiring harnesses.
- If the intake manifold was removed, reinstall it carefully.
Double-check all connections to ensure everything is secure and properly aligned.
Final Steps
Once all components are reconnected, you can proceed with the final steps of the installation:
- Reconnect the negative battery terminal.
- Start the engine and check for any exhaust leaks.
- Allow the engine to reach operating temperature and monitor for any issues.
After confirming everything is functioning correctly, lower the vehicle from the jack stands and take it for a test drive.
Conclusion
Installing BRZ headers from Perrin or Manley can be a rewarding project that enhances your vehicle’s performance. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of improved exhaust flow and increased horsepower.
