The Honda S2000 AP2 is a beloved sports car celebrated for its high-revving engine and agile handling. However, many enthusiasts seek to enhance its performance beyond the stock 240 horsepower. This guide will explore various upgrades that can help you achieve a significant boost in power while maintaining reliability.
Understanding the S2000 AP2
The S2000 AP2, produced from 2004 to 2009, features a 2.2-liter F22C1 inline-four engine. This engine is known for its VTEC system, which allows for a seamless transition between low and high RPMs. Before diving into performance upgrades, it’s essential to understand the stock specifications and limitations.
- Engine: 2.2L F22C1 Inline-Four
- Horsepower: 240 hp at 8,300 RPM
- Torque: 162 lb-ft at 6,500 RPM
- Transmission: 6-speed manual
Performance Upgrade Goals
When upgrading your S2000 AP2, it’s crucial to set clear goals. Common objectives include:
- Increasing horsepower and torque
- Improving throttle response
- Enhancing engine sound
- Maintaining reliability and drivability
Essential Upgrades for Power Increase
1. Cold Air Intake
A cold air intake system can improve airflow to the engine, resulting in better combustion and increased power. Look for reputable brands that offer a high-flow filter and a heat shield to prevent hot air intake.
2. Performance Exhaust System
Upgrading the exhaust system can significantly enhance engine performance. A cat-back exhaust system reduces back pressure and allows for better exhaust flow, leading to increased horsepower and a more aggressive sound.
3. ECU Tune
Tuning the engine control unit (ECU) can optimize fuel maps and ignition timing, unlocking additional horsepower. A professional tune tailored to your specific modifications will yield the best results.
4. Upgraded Headers
Performance headers can improve exhaust flow by reducing restrictions. Long-tube headers are particularly effective in maximizing power throughout the RPM range.
5. High-Performance Camshafts
Upgrading to performance camshafts can enhance the engine’s ability to breathe, increasing both horsepower and torque. Choose camshafts designed specifically for the F22C1 engine to ensure compatibility.
Supporting Modifications
In addition to the primary upgrades, several supporting modifications can help maintain reliability and performance:
- High-Performance Radiator: Keeps engine temperatures in check during spirited driving.
- Upgraded Fuel Injectors: Ensures adequate fuel delivery for increased horsepower.
- Aftermarket Clutch: Handles the increased power without slipping.
- Suspension Upgrades: Improves handling and stability at higher speeds.
Conclusion
Upgrading your Honda S2000 AP2 from stock to 240 horsepower is an achievable goal with the right modifications. By focusing on key performance upgrades and supporting modifications, you can enjoy a thrilling driving experience while maintaining the reliability that the S2000 is known for. Always remember to consult with professionals and do thorough research before making any modifications to ensure the best results.
