by

The RX-7 is a legendary sports car known for its lightweight design and exceptional handling. When swapping in a powerful LS engine to achieve 500 horsepower, it’s crucial to consider supporting modifications that will enhance performance, reliability, and drivability. This article explores the best brands and installation tips for supporting mods that will complement your RX-7 LS swap.

Why Supporting Mods are Essential

When upgrading to a 500 hp LS engine, the stock components of the RX-7 may struggle to keep up. Supporting mods help ensure that the vehicle can handle the increased power and improve overall performance. Here are some reasons why supporting mods are essential:

  • Improved Reliability: Upgraded components can withstand higher stress levels.
  • Enhanced Performance: Supporting mods can improve acceleration, braking, and handling.
  • Better Drivability: Proper tuning and components can make the car more enjoyable to drive.

Key Supporting Mods for a 500 HP RX-7 LS Swap

1. Fuel System Upgrades

A reliable fuel system is vital for supporting high horsepower. Here are some recommended upgrades:

  • Fuel Pumps: Consider using a high-flow fuel pump from brands like Walbro or DeatschWerks.
  • Fuel Injectors: Upgrade to larger injectors (e.g., 60 lb/hr or more) from Injector Dynamics or Siemens Deka.
  • Fuel Lines: Use -6AN or -8AN fuel lines for better flow and pressure management.

2. Cooling System Enhancements

With increased power comes increased heat. Upgrading the cooling system is crucial to prevent overheating:

  • Radiator: A performance radiator from Griffin or Mishimoto can help manage temperatures.
  • Fans: Consider electric fans for better airflow and efficiency.
  • Coolant Hoses: Use high-quality silicone hoses to withstand higher temperatures.

3. Exhaust System Upgrades

An efficient exhaust system is essential for maximizing engine performance. Here are some options:

  • Headers: Long-tube headers from Hooker or American Racing can improve exhaust flow.
  • Cat-Back Exhaust: A quality cat-back system from Borla or MagnaFlow enhances sound and performance.
  • High-Performance Catalytic Converters: Consider high-flow cats to reduce back pressure.

4. Suspension Upgrades

To handle the power effectively, upgrading the suspension is necessary for better handling and stability:

  • Coilovers: Brands like BC Racing or Tein offer adjustable coilovers for improved handling.
  • Sway Bars: Upgraded sway bars from Whiteline or Hotchkis can reduce body roll.
  • Bushings: Consider polyurethane bushings for better response and durability.

5. Transmission and Drivetrain Upgrades

To handle the increased power, upgrading the transmission and drivetrain components is critical:

  • Transmission: A T56 transmission is a popular choice for handling high power.
  • Driveshaft: Upgrade to a stronger aluminum or carbon fiber driveshaft for improved durability.
  • Differential: Consider a limited-slip differential for better traction.

Installation Tips for Supporting Mods

Proper installation is key to ensuring that supporting mods function effectively. Here are some tips:

  • Follow Manufacturer Instructions: Always refer to the installation manuals provided by the manufacturers.
  • Use Quality Tools: Invest in good tools to avoid damaging components during installation.
  • Check Clearances: Ensure that all components fit properly without interference.
  • Professional Help: Don’t hesitate to seek professional assistance if you’re unsure about the installation process.

Tuning Your RX-7 After Mods

After installing supporting mods, tuning is essential to maximize performance. Here are some steps to follow:

  • ECU Tuning: Use a reputable tuner who specializes in LS swaps to recalibrate your ECU.
  • Dyno Testing: Perform dyno testing to ensure optimal performance and reliability.
  • Monitor Parameters: Keep an eye on air-fuel ratios, boost levels, and temperatures during tuning.

Conclusion

Supporting mods are crucial for a successful 500 hp RX-7 LS swap. By investing in quality components and following proper installation and tuning procedures, you can enhance the performance and reliability of your vehicle. Choose the right brands and take the time to do it right, and your RX-7 will be ready to deliver an exhilarating driving experience.
