Installing a supercharger can significantly increase horsepower, allowing the BRZ to exceed 300 hp. In this guide, we will walk you through the step-by-step process of installing a supercharger on your Subaru BRZ.
Tools and Materials Needed
- Supercharger kit specific to Subaru BRZ
- Socket set and wrenches
- Torque wrench
- Screwdrivers (flathead and Phillips)
- Ratchet extensions
- Engine oil
- Coolant
- Vacuum line and clamps
- Wire connectors
- Safety glasses and gloves
Preparation Steps
Before beginning the installation, ensure you have a clean and well-lit workspace. Gather all the tools and materials listed above. It’s also recommended to review the supercharger kit’s manual for any specific instructions or requirements.
1. Disconnect the Battery
Safety is paramount. Start by disconnecting the negative terminal of the battery to prevent any electrical shorts during the installation process.
2. Remove the Engine Cover
Next, remove the engine cover by unscrewing the bolts that hold it in place. Set the cover aside in a safe location.
Removing Existing Components
To install the supercharger, certain components must be removed to provide access to the engine. Follow these steps carefully.
1. Remove the Intake Manifold
Start by disconnecting any electrical connectors and vacuum lines attached to the intake manifold. Use a socket set to remove the bolts securing the manifold. Gently lift it off and set it aside.
2. Remove the Throttle Body
Next, detach the throttle body from the intake manifold. Disconnect the throttle position sensor and any other connections before removing the bolts that hold it in place.
Installing the Supercharger
With the necessary components removed, you can now proceed to install the supercharger. Follow these steps for a successful installation.
1. Position the Supercharger
Carefully place the supercharger onto the engine. Ensure that it aligns correctly with the mounting points. Use the provided hardware to secure it in place, but do not fully tighten the bolts yet.
2. Connect the Intake and Throttle Body
Reconnect the throttle body to the supercharger. Make sure all electrical connectors and vacuum lines are properly attached. Follow the supercharger kit instructions for specific connection details.
3. Install the Intercooler (if applicable)
If your supercharger kit includes an intercooler, install it according to the manufacturer’s guidelines. This may involve additional piping and connections.
Finalizing the Installation
After securing the supercharger and any additional components, it’s time to finalize the installation.
1. Tighten All Bolts
Using a torque wrench, tighten all bolts to the specifications provided in the supercharger kit manual. This ensures that everything is securely fastened and prevents any leaks.
2. Reconnect the Battery
Reconnect the negative terminal of the battery. Ensure that all connections are secure and that there are no loose wires.
3. Check Fluid Levels
Before starting the engine, check the engine oil and coolant levels. Top off if necessary to ensure proper operation.
Testing the Installation
Once everything is installed and checked, it’s time to test the supercharger.
1. Start the Engine
Start the engine and listen for any unusual sounds. Allow it to idle for a few minutes while checking for any leaks or issues.
2. Take a Test Drive
After ensuring everything is functioning correctly, take the car for a test drive. Pay attention to the throttle response and overall performance. You should notice a significant increase in power.
Conclusion
Installing a supercharger on your Subaru BRZ can transform your driving experience, pushing the horsepower beyond 300 hp. By following this step-by-step guide, you can successfully enhance your vehicle’s performance while enjoying the process. Always remember to consult the specific supercharger kit instructions and consider professional assistance if needed.
