The Honda S2000 AP1 is a beloved sports car known for its high-revving engine and exceptional handling. Many enthusiasts seek ways to enhance its performance without breaking the bank. One of the most effective methods to gain horsepower is through an intake upgrade and an ECU tune. In this article, we will explore how to add 20-25 horsepower for under $1,000.
Understanding the S2000 AP1
The S2000 AP1 was produced between 1999 and 2003, featuring a 2.0L F20C engine that produces around 240 horsepower. While this is impressive for a naturally aspirated engine, many owners desire more power. Upgrading the intake and tuning the ECU are two of the most effective modifications to achieve this goal.
Benefits of an Intake Upgrade
Upgrading the intake system can significantly improve airflow to the engine, resulting in better combustion and increased power. Here are some key benefits:
- Improved Airflow: A high-performance intake allows for more air to enter the engine, enhancing power output.
- Better Throttle Response: Increased airflow leads to quicker throttle response, making the car feel more lively.
- Enhanced Sound: A new intake can provide a more aggressive engine note, adding to the driving experience.
Choosing the Right Intake
When selecting an intake for your S2000 AP1, consider the following options:
- Cold Air Intakes: These systems draw air from outside the engine bay, providing cooler air for improved performance.
- Short Ram Intakes: These are easier to install and often provide a noticeable sound improvement, though they may draw in warmer air.
- Brand Recommendations: Popular brands include AEM, K&N, and Injen, known for their quality and performance gains.
ECU Tuning: Unlocking Potential
After upgrading the intake, the next step is to tune the ECU. This process recalibrates the engine’s computer to optimize performance with the new intake system.
Benefits of ECU Tuning
ECU tuning offers several advantages:
- Increased Horsepower: A proper tune can unlock additional horsepower by adjusting fuel maps and ignition timing.
- Improved Fuel Efficiency: A well-tuned engine can achieve better fuel economy, making it more efficient.
- Custom Settings: Tuning allows for personalized settings based on driving style and preferences.
How to Tune Your ECU
Tuning your ECU can be done in several ways:
- Standalone ECU: This option replaces the factory ECU and allows for extensive customization but can be more expensive.
- Reflash Tuning: This method involves reprogramming the stock ECU with a performance map, often done through a handheld tuner.
- Professional Tuning: Hiring a professional tuner can yield the best results, as they can tailor the tune specifically to your setup.
Cost Breakdown
Here’s a rough cost breakdown to achieve the performance gains:
- Intake System: $200 – $500 depending on the brand and type.
- ECU Tune: $300 – $600 for a reflash or professional tune.
- Total Estimated Cost: $500 – $1,100.
Installation Tips
Installing an intake and tuning the ECU can be done by most enthusiasts with basic mechanical skills. Here are some tips:
- Read Instructions: Always follow the manufacturer’s instructions for installation.
- Use Quality Tools: Ensure you have the right tools to avoid damaging parts during installation.
- Take Your Time: Rushing can lead to mistakes; take your time to ensure everything is done correctly.
Conclusion
Upgrading the intake and tuning the ECU of your S2000 AP1 is an effective way to gain 20-25 horsepower for under $1,000. With the right parts and a proper tune, you can enhance your driving experience and enjoy the thrill of increased performance. Whether you choose to do it yourself or seek professional help, these modifications can transform your S2000 into an even more exciting sports car.
