- Ideal for 300-400 horsepower applications
- Quick spool time for improved throttle response
Preparation for Installation
Proper preparation is key to a successful turbo upgrade. Follow these steps to ensure everything is in order before you begin the installation.
- Gather necessary tools: socket set, wrenches, torque wrench, and screwdrivers.
- Purchase required parts: turbocharger, intercooler, piping, and necessary gaskets.
- Ensure your Miata is in good mechanical condition before upgrading.
- Consider upgrading supporting components like fuel injectors and the fuel pump.
Installation Steps
1. Remove the Existing Turbocharger
Start by removing the existing turbocharger. This involves disconnecting the intake and exhaust components, as well as any associated sensors and hoses. Make sure to label parts for easier reassembly.
2. Install the Precision 5857 Turbo
Carefully install the Precision 5857 Turbo in the same location as the previous turbo. Ensure that all gaskets are replaced and that the turbo is properly aligned with the exhaust manifold.
3. Connect the Intercooler and Piping
Next, connect the intercooler and piping. Make sure all connections are secure and that there are no leaks. Properly routing the piping can help maximize airflow and efficiency.
4. Upgrade Fuel System Components
To support the increased power, upgrade your fuel injectors and fuel pump. This ensures that your engine receives the necessary fuel to match the turbo’s output.
5. Reconnect Electrical Components
Reconnect any electrical components and sensors that were disconnected during the removal process. Double-check that everything is properly connected to avoid any issues.
Tuning Your Miata
After installation, tuning your Miata is crucial for maximizing performance and ensuring engine safety. Consider these tuning options:
- Use a standalone engine management system for precise control.
- Consult a professional tuner with experience in turbocharged Miatas.
- Monitor air-fuel ratios and boost levels during tuning.
Post-Installation Checks
Once the installation and tuning are complete, perform a series of checks to ensure everything is functioning correctly:
- Check for any boost leaks in the intake system.
- Inspect all connections for leaks or loose fittings.
- Monitor engine temperatures and performance during initial drives.
Conclusion
Upgrading to a Precision 5857 Turbo on your Miata can yield incredible power gains when done correctly. By following these best practices, you can ensure a successful installation and enjoy the enhanced performance of your vehicle.
