The Honda S2000 AP1 is a beloved sports car known for its high-revving engine and exceptional handling. For enthusiasts looking to increase performance, achieving 250+ wheel horsepower (WHP) is a common goal. In this article, we will explore the modifications, associated costs, and real-world results of pushing the S2000 AP1 to this power level.
Understanding the Honda S2000 AP1
The Honda S2000 AP1 was produced from 1999 to 2003 and features a 2.0-liter F20C engine. This engine is known for its high specific output, making it a great candidate for tuning. The AP1 variant produces 240 horsepower at 8,300 RPM and 153 lb-ft of torque at 7,500 RPM. To achieve over 250 WHP, several modifications can be made.
Key Modifications for 250+ WHP
To reach the 250 WHP mark, a combination of engine modifications, tuning, and supporting parts is necessary. Here are some of the essential modifications:
- Cold Air Intake: Improves airflow to the engine.
- High-Performance Exhaust System: Reduces back pressure and enhances exhaust flow.
- Tune: A proper ECU tune maximizes performance gains from modifications.
- Upgraded Fuel System: Ensures adequate fuel delivery for increased power.
- Forced Induction: A supercharger or turbocharger can significantly boost power output.
- Upgraded Internals: Forged pistons and rods for increased reliability under boost.
Cold Air Intake
A cold air intake system replaces the factory airbox and allows for cooler, denser air to enter the engine. This modification is relatively inexpensive and can provide a noticeable increase in power, especially when combined with other upgrades.
High-Performance Exhaust System
Upgrading to a high-performance exhaust system helps to decrease back pressure and improve exhaust flow. A cat-back exhaust system, along with high-flow catalytic converters, can enhance the sound and performance of the S2000.
Tuning
After making modifications, a professional tune is essential to optimize the engine’s performance. A proper ECU remap can unlock additional power and ensure that the engine runs smoothly and reliably.
Upgraded Fuel System
As power increases, so does the demand for fuel. Upgrading the fuel pump and injectors ensures that the engine receives adequate fuel supply, especially when running a higher boost level.
Forced Induction
For those looking for significant power gains, adding a supercharger or turbocharger is the most effective option. These systems can increase horsepower dramatically, often exceeding 250 WHP with proper tuning and supporting modifications.
Upgraded Internals
When pushing the limits of the S2000’s engine, upgrading to forged internals can provide additional reliability. Forged pistons and connecting rods can withstand higher power levels and reduce the risk of engine failure.
Cost Breakdown of Modifications
Understanding the costs associated with each modification is crucial for planning your project. Here’s a breakdown of estimated costs for achieving 250+ WHP on a Honda S2000 AP1:
- Cold Air Intake: $200 – $400
- High-Performance Exhaust System: $800 – $1,500
- Tuning: $500 – $1,200
- Upgraded Fuel System: $300 – $800
- Forced Induction Kit: $3,000 – $8,000
- Upgraded Internals: $1,500 – $3,000
Real-World Results
Many S2000 owners have successfully achieved 250+ WHP with the right combination of modifications. Here are some real-world examples:
- Example 1: An S2000 with a supercharger, upgraded fuel system, and a custom tune achieved 270 WHP on a dyno.
- Example 2: A turbocharged S2000 with forged internals and a high-performance exhaust system reached 300 WHP.
- Example 3: A well-tuned NA S2000 with intake and exhaust modifications achieved 250 WHP.
Conclusion
Achieving 250+ WHP on a Honda S2000 AP1 is an attainable goal with the right modifications and tuning. By investing in quality parts and ensuring proper installation and tuning, enthusiasts can enjoy a thrilling driving experience with increased power and performance. Always remember to consider the reliability and longevity of your engine when making modifications.
