The Nissan S13 240SX has long been a favorite among car enthusiasts and tuners alike. With its lightweight chassis and rear-wheel-drive layout, it provides an excellent platform for performance upgrades. One of the most popular modifications is the installation of a turbocharger, which can significantly boost horsepower. In this article, we will explore how a real owner achieved an impressive 320 horsepower with a custom turbo setup on their S13 240SX.
Understanding the S13 240SX
The S13 240SX, produced from 1989 to 1994, is known for its nimble handling and potential for modification. It comes equipped with a naturally aspirated 2.4L inline-four engine, which, while capable, often leaves enthusiasts wanting more power. This is where turbocharging comes into play.
The Turbo Setup
For the owner of the S13 240SX in question, the goal was to achieve a reliable 320 horsepower. To accomplish this, a custom turbo setup was designed, incorporating several key components:
- Garrett GT2871R Turbocharger
- Custom manifold
- Upgraded fuel injectors
- High-flow fuel pump
- Standalone engine management system
Choosing the Right Turbocharger
The choice of turbocharger is crucial for achieving the desired power output. The Garrett GT2871R is known for its ability to produce significant horsepower while maintaining good response. This turbocharger is capable of supporting up to 400 horsepower, making it a suitable choice for the owner’s goals.
Custom Manifold and Exhaust
A custom manifold was fabricated to ensure proper fitment and optimal flow for the turbocharger. This is essential for maximizing the efficiency of the turbo setup. Additionally, a high-flow exhaust system was installed to reduce back pressure and improve overall performance.
Fuel System Upgrades
To support the increased horsepower, the fuel system required significant upgrades. The owner opted for larger fuel injectors and a high-flow fuel pump to ensure adequate fuel delivery under boost. These components help maintain the correct air-fuel ratio, which is critical for engine performance and longevity.
Tuning the Setup
With the hardware installed, the next step was tuning. A standalone engine management system was chosen to provide the flexibility needed for optimal tuning. This allows for precise adjustments to fuel maps, ignition timing, and boost levels, ensuring the engine runs smoothly and efficiently.
Dyno Testing
After the setup was complete, the car was taken to a dynamometer for testing. The results were impressive, with the S13 240SX producing a peak horsepower of 320 at the wheels. This marked a significant increase over the stock output, demonstrating the effectiveness of the custom turbo setup.
Driving Experience
With the new turbo setup, the driving experience of the S13 240SX transformed dramatically. The added power and torque provided exhilarating acceleration, while the lightweight chassis allowed for nimble handling. Enthusiasts reported that the car felt more alive than ever before.
Conclusion
The journey to achieving 320 horsepower with a custom turbo setup on the S13 240SX showcases the potential of this iconic platform. By carefully selecting components and tuning the setup, the owner was able to transform their vehicle into a powerful and enjoyable machine. For those considering similar modifications, this build serves as a testament to what can be achieved with dedication and the right knowledge.
