Best Supporting Mods for 2jz Swap 240sx: Upgrading Suspension, Drivetrain, and Cooling Systems

by

The Nissan 240SX is a popular platform for car enthusiasts, especially when it comes to engine swaps. One of the most sought-after swaps is the Toyota 2JZ engine, known for its reliability and performance. However, to fully harness the potential of the 2JZ engine, upgrading supporting mods is essential. This article will explore the best supporting mods for a 2JZ swap in a 240SX, focusing on upgrading suspension, drivetrain, and cooling systems.

Upgrading Suspension

A solid suspension setup is crucial for handling the increased power and torque from the 2JZ engine. Here are some key upgrades to consider:

  • Coilovers: Investing in a quality set of coilovers will improve handling and allow for adjustable ride height. Look for brands like BC Racing or Fortune Auto.
  • Strut Braces: Adding front and rear strut braces helps to stiffen the chassis, reducing flex during cornering.
  • Upgraded Sway Bars: Stiffer sway bars will minimize body roll and enhance cornering stability.
  • Control Arms: Adjustable control arms can help fine-tune suspension geometry for better alignment and handling.

Enhancing Drivetrain

The drivetrain is another critical area that requires attention when swapping in a 2JZ engine. Here are some essential upgrades:

  • Transmission Swap: Consider using a compatible transmission such as the R154 or a Getrag 6-speed for optimal power handling.
  • Clutch Upgrade: A high-performance clutch is necessary to manage the increased power. Look for brands like Exedy or ACT.
  • Driveshaft: Upgrading to a stronger driveshaft can prevent failures under high torque situations.
  • Rear Differential: A limited-slip differential (LSD) will improve traction and handling, especially during aggressive driving.

Improving Cooling Systems

Keeping the 2JZ engine cool is vital for performance and longevity. Here are some cooling upgrades to consider:

  • Upgraded Radiator: A larger, high-performance radiator will help maintain optimal engine temperatures. Consider options from Mishimoto or Koyo.
  • Cooling Fans: Installing electric cooling fans can improve airflow and reduce engine temperatures during operation.
  • Oil Cooler: An oil cooler helps maintain lower oil temperatures, which is essential for engine health during high-performance driving.
  • Intercooler: If you’re running a turbo setup, a larger intercooler will help reduce intake temperatures, improving performance.

Conclusion

Upgrading the suspension, drivetrain, and cooling systems are critical steps in maximizing the performance of a 2JZ swap in a Nissan 240SX. By investing in quality supporting mods, you can ensure that your vehicle handles well, drives smoothly, and maintains optimal temperatures, ultimately leading to a more enjoyable driving experience. With the right upgrades, your 240SX can become a formidable machine on both the street and the track.
