The Mazda MX-5 Miata is a beloved sports car known for its lightweight design and engaging driving experience. For enthusiasts looking to enhance performance, the NA Miata (produced from 1989 to 1997) offers numerous opportunities for power gains. With the right modifications, it’s possible to achieve up to 30 horsepower without extensive engine work. Here are some easy mods to consider.
1. Cold Air Intake
Installing a cold air intake system is one of the simplest ways to increase horsepower. By allowing cooler air to enter the engine, these systems improve combustion efficiency.
- Improved airflow increases power output.
- Enhanced engine sound adds to the driving experience.
2. Exhaust System Upgrade
Upgrading the exhaust system can significantly enhance performance by reducing back pressure. A high-flow exhaust allows exhaust gases to exit more freely, which can lead to noticeable power gains.
- Cat-back systems are popular for their balance of sound and performance.
- Headers can further improve exhaust flow and increase horsepower.
3. ECU Tune
A performance ECU tune adjusts the engine’s fuel and ignition maps to optimize performance. This modification can unlock additional horsepower by maximizing the efficiency of the engine.
- Custom tunes can be tailored to specific modifications.
- Easy to revert back to stock settings if needed.
4. Lightweight Flywheel
Replacing the stock flywheel with a lightweight version can improve throttle response and acceleration. A lighter flywheel reduces the rotational mass, allowing the engine to rev more freely.
- Improved acceleration can enhance driving enjoyment.
- Installation can be done during a clutch replacement for convenience.
5. Performance Spark Plugs
Upgrading to performance spark plugs can improve ignition efficiency, leading to better combustion and power gains. High-performance plugs are designed to handle higher temperatures and provide a more reliable spark.
- Better throttle response and smoother operation.
- Longer lifespan compared to standard plugs.
6. Suspension Upgrades
While not directly a power gain, upgrading the suspension can improve handling, allowing drivers to take full advantage of the power the Miata produces. Better grip and stability can enhance overall performance on the road or track.
- Coilovers can provide adjustable ride height and damping.
- Upgraded sway bars can reduce body roll and improve cornering.
7. Short Throw Shifter
A short throw shifter reduces the distance the shifter needs to travel between gears, allowing for quicker shifts. This can improve the driving experience and make the most of the added power.
- Faster gear changes can enhance acceleration.
- Improved feel and feedback during shifting.
Conclusion
With these simple modifications, NA Miata owners can achieve significant power gains of up to 30 horsepower. Each mod contributes to a more engaging driving experience, allowing enthusiasts to enjoy their Miata to the fullest. Whether you choose one or all of these upgrades, the result will be a more spirited and enjoyable ride.
