by

The Nissan 240SX is a popular platform for engine swaps, particularly with the legendary Toyota 2JZ engine. This combination has the potential to create a powerful drift or street machine. Achieving 700 horsepower with a 2JZ swap in a 240SX can be done without breaking the bank. Here, we will explore cost-effective upgrades that can help you reach that impressive horsepower goal.

Understanding the 2JZ Engine

The 2JZ engine, particularly the 2JZ-GTE variant, is known for its robust construction and tuning potential. Originally designed for the Toyota Supra, this inline-six engine can handle significant power increases when properly supported with the right components.

Essential Upgrades for Power

To hit the 700 hp mark, several key upgrades are essential. Below are some of the most cost-effective modifications you can make:

  • Turbo Upgrade: Replacing the stock turbo with a larger unit, such as a Precision 6266 or Garrett GTX3076R, can significantly increase airflow and power.
  • Fuel System Upgrade: Upgrading to larger injectors (1000cc or more) and a high-flow fuel pump will ensure that your engine receives enough fuel for higher horsepower levels.
  • Intercooler Upgrade: A larger intercooler will help reduce intake temperatures, improving performance and reliability under boost.
  • Exhaust System: A high-flow downpipe and cat-back exhaust will reduce back pressure and improve exhaust flow.
  • ECU Tuning: A proper tune is crucial for maximizing performance and ensuring the engine runs smoothly at higher power levels.

Supporting Modifications

In addition to the essential upgrades, consider the following supporting modifications to ensure reliability and performance:

  • Upgraded Engine Management: A standalone ECU or a piggyback system like the AEM Infinity or Greddy E-Manage can provide more tuning options and control.
  • Strengthened Internals: If you plan on pushing beyond 700 hp, consider upgrading to forged pistons and rods for added reliability.
  • Cooling System: An upgraded radiator and oil cooler will help maintain optimal operating temperatures during high-performance driving.
  • Transmission Upgrade: Consider upgrading to a stronger transmission or adding a transmission cooler to handle the increased power.
  • Suspension and Brakes: Upgrading your suspension and brake system is vital for handling the increased power and ensuring safety.

Budgeting for Your Build

Building a 2JZ swapped 240SX to reach 700 hp can be done on a budget if you plan carefully. Here are some tips for budgeting your upgrades:

  • Research Parts: Look for used or refurbished parts to save money. Many enthusiasts sell parts after upgrading their builds.
  • Prioritize Upgrades: Focus on the most impactful upgrades first, such as the turbo and fuel system, before moving on to supporting modifications.
  • DIY Installation: If you have mechanical skills, consider doing the work yourself to save on labor costs.
  • Join Online Communities: Engage with online forums and groups for advice, support, and potential deals on parts.
  • Plan for Future Upgrades: Consider your long-term goals and plan your upgrades accordingly to avoid spending money twice.

Conclusion

Achieving 700 hp in a 2JZ swapped 240SX is an exciting goal that can be accomplished with careful planning and cost-effective upgrades. By focusing on essential modifications and supporting systems, you can create a powerful and reliable vehicle that performs well both on the street and the track.
