The Honda S2000 is a beloved sports car known for its high-revving engine and responsive handling. For enthusiasts looking to increase performance, a turbo kit can significantly enhance power output. In this article, we will explore the parts selection and performance breakdown for a 400hp turbo build on the S2000.
Understanding the S2000 Platform
The S2000 was produced from 1999 to 2009 and features a lightweight chassis and a naturally aspirated 2.0L or 2.2L inline-four engine. Its design emphasizes balance and agility, making it a popular choice for tuning. To achieve 400 horsepower, careful consideration of parts and tuning is essential.
Choosing the Right Turbo Kit
When selecting a turbo kit for the S2000, several options are available. A complete turbo kit typically includes the turbocharger, manifold, intercooler, piping, and necessary hardware. Here are some popular choices:
- HKS GT2835 Turbo Kit
- Greddy TD05 Turbo Kit
- Comp Turbo CT4 Turbo Kit
Key Components of a Turbo Kit
Each turbo kit will have specific components that contribute to performance. Here are the key parts to consider:
- Turbocharger: The heart of the turbo kit, responsible for compressing air.
- Manifold: Connects the turbo to the engine and directs exhaust gases.
- Intercooler: Cools the compressed air before it enters the engine.
- Piping: Connects the various components of the turbo system.
- Wastegate: Regulates boost pressure to prevent over-boosting.
- Blow-off Valve: Releases excess pressure to prevent compressor surge.
Supporting Modifications
To safely achieve 400hp, additional modifications are necessary to support the increased power. These modifications ensure reliability and performance. Here are some critical upgrades:
- Fuel System: Upgraded fuel injectors and fuel pump are essential for adequate fuel delivery.
- Engine Management: A standalone ECU or reflash is crucial for tuning the engine to work with the turbo setup.
- Exhaust System: A high-flow exhaust system reduces back pressure and improves performance.
- Clutch: An upgraded clutch is necessary to handle the increased power and torque.
- Cooling System: An upgraded radiator and oil cooler can help manage temperatures.
Performance Breakdown
Once the turbo kit and supporting modifications are installed, it’s essential to understand the performance characteristics of the build. Here’s a breakdown of what to expect:
- Power Output: With proper tuning, the S2000 can achieve around 400hp at the crank.
- Torque: Expect a significant increase in torque, especially in the mid-range.
- Boost Levels: Typically, a boost level of 8-10 psi is sufficient for 400hp.
- Response: Turbo lag may be present, but a properly sized turbo will minimize this.
- Reliability: With quality parts and proper tuning, the build can be reliable for daily driving.
Tuning for Optimal Performance
Tuning is a critical aspect of any turbo build. A professional tuner will map the engine to ensure optimal performance and reliability. Here are some tuning considerations:
- Air-Fuel Ratio: Maintaining the correct A/F ratio is vital for engine health.
- Ignition Timing: Proper timing adjustments can help prevent knock and improve performance.
- Boost Control: Fine-tuning boost levels can optimize power delivery.
- Data Logging: Continuous monitoring of engine parameters ensures safe operation.
Conclusion
The S2000 turbo kit 400hp build is an exciting project for enthusiasts looking to unleash the full potential of their vehicle. By carefully selecting the right parts and making necessary modifications, achieving a reliable and powerful setup is possible. With proper tuning, the S2000 can deliver exhilarating performance while maintaining its iconic driving experience.
