The Mazda MX-5 Miata, particularly the NB generation, is a beloved sports car known for its lightweight design and exceptional handling. However, many enthusiasts seek to enhance its performance, aiming for the coveted 150 wheel horsepower (whp). This article explores the best exhaust systems and ECU tuning options to help you achieve this goal.
Understanding Wheel Horsepower
Wheel horsepower (whp) refers to the power output measured at the wheels of the vehicle, as opposed to the engine’s crank horsepower (chp). Achieving 150 whp in an NB Miata requires a combination of modifications that improve airflow and optimize engine performance.
Key Modifications for Achieving 150 Whp
- High-Performance Exhaust System
- ECU Tune
- Upgraded Intake System
- Performance Headers
- Lightweight Flywheel
High-Performance Exhaust System
A quality exhaust system is crucial for improving airflow and increasing horsepower. A cat-back exhaust system is a popular choice among Miata enthusiasts. It replaces the factory exhaust from the catalytic converter back, providing better flow and a more aggressive sound.
- Brands to Consider:
- MX-5 Miata Racing Beat Exhaust
- Borla Exhaust Systems
- Greddy SP Exhaust
ECU Tune
After upgrading the exhaust, an ECU tune is essential to maximize the benefits of the new modifications. Tuning the ECU adjusts fuel maps, ignition timing, and other parameters to optimize performance.
- Tuning Options:
- Standalone ECU (e.g., Megasquirt)
- Reflash Options (e.g., EcuTek)
- Custom Dyno Tuning
Additional Modifications to Consider
To further enhance performance and reach the 150 whp target, consider these additional modifications:
- Upgraded Intake System: A high-flow air intake can improve engine breathing, contributing to better performance.
- Performance Headers: Upgrading to aftermarket headers can significantly enhance exhaust flow.
- Lightweight Flywheel: Reducing rotational mass can improve throttle response and acceleration.
Conclusion
Achieving 150 wheel horsepower in an NB Miata is an attainable goal with the right modifications. By investing in a high-performance exhaust system and a proper ECU tune, along with additional enhancements, you can unlock the full potential of your Miata. Always remember to consult with professionals when making significant modifications to ensure optimal results and reliability.
