The NA Miata, known for its lightweight and nimble handling, can be an exhilarating platform for performance upgrades. One of the most effective ways to boost its horsepower to over 150 is by installing a turbocharger. This article will explore various turbocharger options and provide installation tips to help you achieve your horsepower goals.
Understanding Turbocharging
Turbocharging is a method of forced induction that increases an engine’s efficiency and power output. By forcing more air into the combustion chamber, a turbocharger allows for more fuel to be burned, resulting in increased horsepower.
Choosing the Right Turbocharger
When selecting a turbocharger for your NA Miata, consider the following options:
- Garrett GT28R: A popular choice for its balance of performance and reliability.
- Holset HX35: Known for its durability and ability to support higher horsepower levels.
- Precision 5858: Offers excellent spool time and power potential for street applications.
Installation Tips
Installing a turbocharger requires careful planning and execution. Here are some essential tips to ensure a successful installation:
- Gather Necessary Tools: Ensure you have all the required tools, including wrenches, sockets, and a torque wrench.
- Follow a Reliable Guide: Use a detailed installation guide specific to your chosen turbocharger model.
- Upgrade Supporting Components: Consider upgrading fuel injectors, fuel pump, and intercooler for optimal performance.
- Check for Exhaust Leaks: After installation, inspect the exhaust system for any leaks that could affect performance.
Tuning Your Miata
After installing the turbocharger, tuning is crucial to maximize performance and ensure engine longevity. Here are some tuning options:
- ECU Remapping: Adjust the engine control unit settings to accommodate the increased airflow and fuel requirements.
- Standalone ECU: For advanced users, a standalone ECU can provide complete control over engine parameters.
- Dyno Tuning: Consider visiting a professional tuner to achieve the best results tailored to your setup.
Common Challenges and Solutions
While turbocharging your NA Miata can yield impressive results, you may encounter some challenges. Here are common issues and their solutions:
- Boost Leaks: Regularly check all connections and hoses for leaks that can reduce performance.
- Overheating: Ensure proper cooling by upgrading the radiator and using a high-performance oil cooler.
- Fuel Supply Issues: Monitor fuel pressure and consider upgrading the fuel system if necessary.
Conclusion
Achieving 150+ horsepower in your NA Miata through turbocharging is an exciting project that can significantly enhance your driving experience. By selecting the right turbocharger, following proper installation techniques, and tuning your vehicle, you can unlock the full potential of your Miata.
