Top Supporting Mods for Ls Swap 240sx: Boosting Power and Drivability with Coilovers, Upgraded Diff, and Fuel System

by

The Nissan 240SX is a beloved platform for car enthusiasts, particularly for those looking to swap in a powerful LS engine. This swap not only increases horsepower but also enhances the overall driving experience. However, to fully realize the potential of an LS swap, several supporting modifications are essential. In this article, we will cover the top supporting mods for an LS swap 240SX, focusing on coilovers, upgraded differentials, and fuel systems.

Coilovers: Enhancing Handling and Stability

One of the most significant upgrades for any LS swapped 240SX is a set of quality coilovers. Stock suspension systems can struggle to handle the increased power and weight of the LS engine. Upgrading to coilovers can greatly improve handling, stability, and ride quality.

  • Adjustability: Coilovers allow for height adjustment and damping settings, enabling drivers to fine-tune their suspension for various driving conditions.
  • Improved Cornering: A lower center of gravity and stiffer springs help the car corner better, reducing body roll and enhancing grip.
  • Customizable Ride Quality: Different coilover brands offer various spring rates and damping options, allowing drivers to select a setup that suits their driving style.

Upgraded Differential: Maximizing Power Transfer

The differential plays a crucial role in transferring power from the engine to the wheels. With an LS swap, the stock differential may not be able to handle the increased torque. Upgrading to a stronger differential is essential for maximizing power transfer and improving drivability.

  • Limited Slip Differential (LSD): An LSD helps distribute power evenly to both wheels, improving traction during acceleration and cornering.
  • Gear Ratio Selection: Choosing the right gear ratio can significantly affect acceleration and top speed, allowing drivers to tailor their setup to their performance goals.
  • Durability: Upgraded differentials are built to withstand higher power levels, reducing the risk of failure under hard driving conditions.

Fuel System: Ensuring Proper Fuel Delivery

With the LS engine’s higher power output, the stock fuel system may struggle to provide adequate fuel delivery. Upgrading the fuel system is vital to ensure the engine runs efficiently and safely.

  • Fuel Pump Upgrade: A high-performance fuel pump is necessary to meet the demands of the LS engine, ensuring sufficient fuel flow under heavy acceleration.
  • Fuel Injectors: Upgrading to larger fuel injectors can provide the necessary fuel to support higher horsepower levels, especially when running forced induction.
  • Fuel Lines: Upgrading to larger diameter fuel lines can reduce restrictions and improve fuel delivery to the engine.

Conclusion

In conclusion, supporting modifications such as coilovers, upgraded differentials, and a robust fuel system are crucial for maximizing the performance and drivability of an LS swapped 240SX. These upgrades not only enhance the car’s handling and stability but also ensure that the engine operates efficiently and reliably. By investing in these key components, enthusiasts can fully enjoy the benefits of their LS swap while maintaining a thrilling driving experience.
