The Z1 Motorsports 370Z headers are a popular upgrade for enthusiasts looking to enhance the performance and sound of their Nissan 370Z. This article provides a detailed step-by-step guide to installing these headers, along with a sound demo to showcase the difference they make.
Tools and Materials Needed
- Socket set
- Torque wrench
- Ratchet and extensions
- Header gaskets
- New bolts (if necessary)
- Jack and jack stands
- Safety glasses
- Gloves
Preparation
Before starting the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Gather all your tools and materials to streamline the process.
Disconnect the Battery
For safety reasons, disconnect the negative terminal of the battery to prevent any electrical issues during the installation.
Raise 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 under the car.
Removing the Stock Headers
To install the Z1 Motorsports headers, you must first remove the stock headers. Follow these steps carefully.
Remove the Undertray (if applicable)
If your 370Z has an undertray, remove it by unscrewing the bolts holding it in place. This will give you better access to the headers.
Disconnect Exhaust Components
Loosen and remove the bolts connecting the exhaust system to the stock headers. Be prepared for some exhaust pressure when removing these components.
Unbolt the Stock Headers
Using a socket set, unbolt the stock headers from the engine block. Take care to keep track of the bolts, as you may need them for the new headers.
Remove the Stock Headers
Once unbolted, carefully remove the stock headers from the engine bay. You may need to maneuver them slightly to get them out.
Installing Z1 Motorsports Headers
With the stock headers removed, you can now install the Z1 Motorsports headers. Follow these steps for a successful installation.
Prepare the New Headers
Before installation, ensure that the new headers are clean and free of any debris. Install new gaskets to prevent exhaust leaks.
Position the New Headers
Carefully position the new headers in place, aligning them with the exhaust ports on the engine block. Make sure the gaskets are properly seated.
Secure the Headers
Using the original or new bolts, secure the headers to the engine block. Tighten them to the manufacturer’s specified torque settings using a torque wrench.
Reconnect Exhaust Components
Reattach the exhaust system to the new headers, ensuring all connections are tight and secure.
Reinstall the Undertray (if applicable)
If you removed an undertray, reinstall it now, securing it with the original bolts.
Final Steps
With the headers installed, it’s time to reconnect the battery and lower the vehicle.
Reconnect the Battery
Reconnect the negative terminal of the battery, ensuring it is tight and secure.
Lower the Vehicle
Carefully lower the vehicle from the jack stands and start the engine to check for any leaks or issues.
