  • Supercharger unit
  • Mounting brackets
  • Intercooler
  • Fuel system upgrades
  • Required tools

Preparation for Installation

Proper preparation is crucial for a successful installation. Here are the steps you should take before starting the installation process:

  • Gather Tools: Ensure you have all necessary tools ready, including wrenches, sockets, and screwdrivers.
  • Read the Manual: Review the installation manual provided with the supercharger for specific instructions and diagrams.
  • Clear Workspace: Create a clean and organized workspace to avoid losing parts and to facilitate the installation process.
  • Check Vehicle Condition: Inspect your BRZ for any existing issues that may affect the installation or performance.

Step-by-Step Installation Guide

1. Remove the Stock Intake System

The first step in the installation process is to remove the stock intake system. This includes the air filter, intake manifold, and any associated piping. Make sure to keep all bolts and clips in a safe place for reinstallation.

2. Install the Supercharger Bracket

Once the stock intake is removed, you can proceed to install the supercharger bracket. Align the bracket with the engine block and secure it using the provided bolts. Ensure it is tightly fastened to avoid any movement during operation.

3. Mount the Rotrex C38 Supercharger

Carefully mount the Rotrex C38 supercharger onto the installed bracket. Make sure it is positioned correctly and secure it with the necessary hardware. Double-check the alignment to prevent any issues later on.

4. Install the Intercooler

The intercooler is essential for cooling the compressed air from the supercharger. Position the intercooler in front of the radiator and connect it to the supercharger using the provided piping. Ensure all connections are tight to prevent leaks.

5. Upgrade the Fuel System

To support the increased airflow from the supercharger, upgrading the fuel system is necessary. Install larger fuel injectors and a high-flow fuel pump. This will ensure your engine receives the proper amount of fuel for optimal performance.

6. Connect Electrical Components

Connect the electrical components, including the supercharger’s power supply and any necessary sensors. Follow the wiring diagram provided in the installation manual to ensure proper connections.

7. Final Checks and Testing

Before starting the engine, perform a thorough inspection of all connections and components. Check for any loose bolts, leaks, or misalignments. Once everything is secured, start the engine and monitor for any unusual sounds or issues.

Tuning Your BRZ After Installation

After installing the Rotrex C38 supercharger, proper tuning is essential to maximize performance and ensure engine longevity. Consider the following:

  • ECU Remapping: A remap of the engine control unit (ECU) is necessary to accommodate the new airflow and fuel requirements.
  • Dyno Testing: Conducting dyno tests can help you fine-tune your setup for optimal performance.
  • Monitoring Tools: Utilize monitoring tools to keep track of air-fuel ratios, boost levels, and engine temperatures.

Common Challenges and Solutions

During the installation process, you may encounter some challenges. Here are a few common issues and their solutions:

  • Alignment Issues: If the supercharger is not aligned properly, it can cause belt wear. Adjust the mounting brackets as needed.
  • Boost Leaks: Any leaks in the piping can reduce performance. Check all connections and use silicone couplers for a secure fit.
  • Electrical Problems: If the supercharger does not engage, double-check all electrical connections and fuses.

Conclusion

Installing the Rotrex C38 supercharger on your BRZ can significantly enhance your vehicle’s performance. By following the steps outlined in this guide, you can achieve a seamless fitment and enjoy the benefits of forced induction. Remember to take your time, double-check your work, and consult professionals if needed.
