The Honda S2000 AP2 is a beloved sports car known for its high-revving engine and exceptional handling. Many enthusiasts seek to enhance its performance, aiming for the coveted 250+ horsepower mark. In this article, we will explore the top power gains achievable through bolt-on modifications.
Understanding the Honda S2000 AP2 Engine
The AP2 variant of the Honda S2000 features a 2.2-liter F20C engine that produces 240 horsepower and 162 lb-ft of torque. This engine is known for its impressive redline and lightweight construction. To achieve higher power outputs, several key modifications can be made without the need for extensive engine work.
Essential Bolt-On Modifications
To reach 250+ horsepower, enthusiasts typically consider the following bolt-on modifications:
- Cold Air Intake
- Performance Exhaust System
- Header Upgrade
- ECU Tune
- High-Performance Spark Plugs
1. Cold Air Intake
A cold air intake system replaces the factory air intake, allowing for cooler, denser air to enter the engine. This modification can lead to noticeable gains in horsepower and throttle response. Popular options include brands like AEM and K&N.
2. Performance Exhaust System
Upgrading to a performance exhaust system not only enhances the sound of the S2000 but also improves exhaust flow. A cat-back exhaust system from manufacturers like Borla or Greddy can provide significant power increases by reducing back pressure.
3. Header Upgrade
Replacing the factory headers with aftermarket options can improve exhaust flow and increase horsepower. Brands like DC Sports and J’s Racing offer headers designed to maximize performance without sacrificing reliability.
4. ECU Tune
An ECU tune is essential for optimizing the performance of your S2000 after making other modifications. Tuning can adjust fuel maps, ignition timing, and other parameters to extract the most power from your engine. Reputable tuning companies like Hondata provide excellent solutions for the AP2.
5. High-Performance Spark Plugs
Upgrading to high-performance spark plugs can improve ignition efficiency and engine response. Brands like NGK and Denso offer spark plugs specifically designed for high-revving engines like the S2000.
Combining Modifications for Maximum Gains
To achieve the best results, it’s important to combine these modifications effectively. A cold air intake paired with a performance exhaust system and a proper ECU tune can yield significant power gains. Each modification complements the others, leading to a smoother and more powerful driving experience.
Additional Considerations
While bolt-on modifications can enhance performance, it’s also essential to consider other factors that contribute to overall vehicle dynamics:
- Suspension Upgrades
- Tire Selection
- Brake System Improvements
Suspension Upgrades
Improving the suspension can enhance handling and stability, allowing you to take full advantage of the increased power. Coilovers or upgraded sway bars can make a significant difference in performance.
Tire Selection
Choosing the right tires is crucial for translating power to the ground. High-performance tires can improve grip and handling, making your S2000 more responsive and enjoyable to drive.
Brake System Improvements
As power increases, so does the need for effective braking. Upgrading to high-performance brake pads and rotors can enhance stopping power, ensuring safety and performance go hand in hand.
Conclusion
Reaching 250+ horsepower in the Honda S2000 AP2 is achievable with the right bolt-on modifications. By focusing on a cold air intake, performance exhaust, header upgrade, ECU tune, and high-performance spark plugs, enthusiasts can unlock the potential of their vehicles. Remember to consider suspension, tires, and brakes to create a well-rounded performance car that’s as fun to drive as it is powerful.
