The Honda S2000 AP2 is a beloved sports car known for its high-revving engine and exhilarating driving experience. For enthusiasts looking to enhance performance, there are several upgrades that can yield significant power gains. In this article, we will explore the top modifications that can help you achieve an impressive 30-50 horsepower increase.
Understanding the Honda S2000 AP2 Engine
The Honda S2000 AP2 is equipped with a 2.2-liter F20C engine, which is renowned for its responsiveness and power delivery. With a factory output of around 240 horsepower, the AP2 offers a solid foundation for performance upgrades. The key to unlocking additional horsepower lies in optimizing the engine’s airflow, fuel delivery, and tuning.
Top Upgrades for Power Gains
- Cold Air Intake
- High-Performance Exhaust System
- ECU Tune
- Headers
- Upgraded Fuel Injectors
- Supercharger or Turbocharger Kit
Cold Air Intake
A cold air intake system replaces the factory air intake, allowing for cooler, denser air to enter the engine. This can lead to improved combustion efficiency and increased horsepower. Many aftermarket options are available that are designed specifically for the S2000 AP2.
High-Performance Exhaust System
Upgrading to a high-performance exhaust system can significantly reduce back pressure and improve exhaust flow. This not only enhances horsepower but also provides a more aggressive sound. Look for systems made from lightweight materials like stainless steel or titanium for optimal performance.
ECU Tune
An ECU tune modifies the engine’s computer settings to optimize performance. By adjusting fuel maps, ignition timing, and other parameters, a proper tune can unlock additional horsepower while ensuring reliability. Many tuners offer specific maps for modified S2000s.
Headers
Upgrading to high-performance headers can improve exhaust flow from the engine, leading to better power gains. Headers replace the factory exhaust manifold and are designed to reduce restrictions, allowing for a more efficient exit of exhaust gases.
Upgraded Fuel Injectors
When increasing horsepower, it’s essential to ensure that the engine receives enough fuel. Upgrading to larger, high-flow fuel injectors can provide the necessary fuel supply for higher horsepower levels, especially when combined with other modifications.
Supercharger or Turbocharger Kit
For those seeking maximum power gains, installing a supercharger or turbocharger kit is an excellent option. These forced induction systems can significantly increase horsepower, often providing gains of 30-50 hp or more. However, they require careful installation and tuning to ensure engine reliability.
Considerations for Upgrading
While the upgrades mentioned above can yield impressive power gains, it’s important to consider a few factors before proceeding:
- Budget: Performance upgrades can vary widely in cost. Set a budget that allows for quality parts and installation.
- Installation: Some upgrades require professional installation, while others can be done as DIY projects. Assess your skills and tools.
- Tuning: After making modifications, proper tuning is crucial to ensure optimal performance and engine safety.
- Reliability: Higher power levels can stress engine components. Consider upgrading supporting parts like the cooling system and drivetrain.
Conclusion
The Honda S2000 AP2 is a fantastic platform for performance upgrades. By implementing the right modifications, enthusiasts can achieve significant power gains of 30-50 hp. Whether you opt for a cold air intake, exhaust system, or a supercharger, each upgrade brings you closer to unlocking the full potential of this iconic sports car.
