Achieving over 700 horsepower in your LS swap 240SX is an exhilarating goal for any car enthusiast. This article will guide you through the essential components needed, focusing on forced induction, fueling systems, and reinforced drivetrain components.
Understanding the LS Engine
The LS engine series, known for its lightweight design and robust performance, has become a popular choice among car builders. With various configurations, achieving high horsepower is feasible with the right modifications.
Forced Induction Options
Forced induction is crucial for reaching 700+ horsepower. There are two primary methods: supercharging and turbocharging. Each has its advantages, and the choice depends on your driving style and goals.
Supercharging
Superchargers provide immediate power by compressing the intake air. They are ideal for street applications where instant throttle response is desired.
- Types of superchargers: Roots, centrifugal, and twin-screw
- Recommended brands: Edelbrock, Whipple, and Magnuson
Turbocharging
Turbochargers utilize exhaust gases to spool up and create boost. They are more efficient at higher RPMs and can provide significant power gains.
- Types of turbochargers: Single turbo, twin turbo, and sequential
- Recommended brands: Garrett, BorgWarner, and Precision Turbo
Fueling System Upgrades
A high-performance fueling system is essential for supporting increased horsepower. Upgrading your injectors, fuel pump, and fuel lines is necessary to ensure adequate fuel delivery.
Fuel Injectors
Choose high-flow fuel injectors that can handle the increased fuel demands of your setup. Look for injectors rated at least 1000cc/min for optimal performance.
Fuel Pump
Upgrading to a high-performance fuel pump is crucial. Consider a pump capable of delivering at least 255 liters per hour (LPH) to support your horsepower goals.
Fuel Lines and Pressure Regulator
Ensure that your fuel lines are rated for high pressure and can withstand the increased flow. A quality adjustable fuel pressure regulator will help maintain optimal fuel pressure.
Reinforced Drivetrain Components
With increased power comes the need for stronger drivetrain components. Reinforcing your drivetrain will help handle the added stress and ensure reliability.
Transmission Upgrades
Consider upgrading to a stronger transmission, such as a T56 or 4L80E, which can handle higher torque loads. Ensure that your transmission is appropriately matched to your engine’s power output.
Driveshaft and Differential
A high-strength driveshaft is essential for transferring power to the wheels. Upgrading to a one-piece driveshaft and a limited-slip differential will enhance traction and performance.
Suspension and Tires
To handle the increased power, upgrade your suspension components and invest in high-performance tires. This will improve traction and stability during acceleration.
Tuning Your Setup
After completing your upgrades, proper tuning is essential. A professional tuner can help you optimize your engine management system for maximum performance and reliability.
Choosing a Tuner
Select a tuner with experience in LS swaps and forced induction setups. They should be familiar with your specific components and have a track record of successful builds.
Tuning Options
- Standalone ECU tuning
- Reflash stock ECU
Conclusion
Achieving 700+ horsepower in your LS swap 240SX is an exciting challenge. By focusing on forced induction, a robust fueling system, and reinforced drivetrain components, you can create a powerful and reliable setup. Remember to prioritize tuning to ensure your vehicle performs at its best.
