The Honda S2000 is a beloved sports car known for its high-revving engine and exceptional handling. With the right modifications, particularly a boosted turbo kit, it can achieve impressive power levels, reaching up to 500 horsepower. This article explores the key tuning and support modifications necessary to unlock the full potential of a boosted S2000 turbo kit.
Understanding the S2000 Engine
The S2000 is powered by a naturally aspirated F20C or F22C engine, depending on the model year. These engines are known for their high specific output, but to achieve 500 horsepower, significant modifications are required. Understanding the engine’s characteristics is essential for effective tuning.
Choosing the Right Turbo Kit
When considering a turbo kit for the S2000, there are several options available. The right kit will depend on your performance goals and budget. Here are some popular choices:
- Greddy Turbo Kit
- HKS Turbo Kit
- Comptech Supercharger Kit (for comparison)
- Custom Turbo Kits
Each kit has its strengths and weaknesses, so research and select one that aligns with your performance goals and driving style.
Key Tuning Modifications
To safely reach 500 horsepower with a turbocharged S2000, several tuning modifications are essential. These modifications help optimize the engine’s performance and ensure reliability under increased power levels.
Engine Management System
Upgrading the engine management system is crucial for tuning a boosted S2000. A standalone engine management system (EMS) allows for precise control over fuel maps, ignition timing, and boost levels. Popular options include:
- Hondata K-Pro
- AEM Infinity
- MoTeC M1
These systems enable tuners to extract maximum performance while maintaining engine safety.
Fuel System Upgrades
With increased horsepower comes the need for more fuel. Upgrading the fuel system is vital for achieving 500 hp. Key upgrades include:
- High-flow fuel injectors
- Upgraded fuel pump
- Fuel pressure regulator
These components ensure that the engine receives an adequate supply of fuel, preventing lean conditions that could damage the engine.
Exhaust System Modifications
A free-flowing exhaust system is essential for maximizing the performance of a turbocharged engine. Upgrades may include:
- High-performance turbo back exhaust
- High-flow catalytic converter
- Upgraded headers
These modifications help reduce back pressure and improve exhaust flow, enhancing overall performance.
Supporting Modifications
In addition to tuning modifications, supporting modifications are necessary to handle the increased power and ensure the longevity of the vehicle. These include:
Upgraded Intercooler
A larger, more efficient intercooler is essential for cooling the intake air, which can become excessively hot under boost. A good intercooler helps maintain optimal air temperatures, improving performance and reliability.
Stronger Internal Components
To handle the increased stress of higher power levels, consider upgrading internal engine components such as:
- Forged pistons
- Forged connecting rods
- Upgraded crankshaft
These components enhance the engine’s strength and durability, allowing it to handle the demands of turbocharging.
Transmission and Drivetrain Upgrades
With increased power, the transmission and drivetrain components must also be upgraded to handle the extra torque. Consider these modifications:
- Performance clutch
- Short throw shifter
- Upgraded differential
These upgrades help ensure that power is effectively transferred to the wheels without slippage or failure.
Tuning and Dyno Testing
Once all modifications are complete, proper tuning is essential. A professional tuner should perform dyno testing to fine-tune the engine parameters. This process ensures that the vehicle runs efficiently and safely at the desired power level.
Conclusion
Achieving 500 horsepower with a boosted S2000 turbo kit is an exciting challenge that requires careful planning and execution. By selecting the right components and ensuring proper tuning, enthusiasts can enjoy the exhilarating performance that this iconic sports car has to offer.
