by

The RX-8 is a beloved sports car known for its unique rotary engine and handling capabilities. However, many enthusiasts have turned to LS swaps to enhance performance and reliability. This article will explore cost-effective supporting modifications that can help you maximize the potential of your RX-8 LS swap, focusing on clutch, ECU, and suspension upgrades.

Clutch Upgrades for RX-8 LS Swap

When swapping an LS engine into an RX-8, upgrading the clutch is essential for handling the increased power. Here are some cost-effective clutch options:

  • Stage 1 Clutch Kits: These kits are designed for street use and can handle moderate power increases. They provide better bite without sacrificing drivability.
  • Stage 2 Clutch Kits: Ideal for those who plan to push their LS swap further, stage 2 kits offer higher torque capacity and improved performance for spirited driving.
  • Lightweight Flywheels: Swapping to a lightweight flywheel can improve throttle response and reduce rotational mass, enhancing overall performance.

Consider brands like Spec, Clutch Masters, and McLeod for reliable and affordable options.

ECU Upgrades for RX-8 LS Swap

The engine control unit (ECU) is crucial for optimizing the performance of your LS engine. Here are some economical ECU upgrade options:

  • Standalone ECUs: A standalone ECU allows for complete control over engine parameters. Brands like Holley and AEM offer user-friendly options that are worth the investment.
  • Tuning Software: If you opt for a factory ECU, consider tuning software like HP Tuners or EFI Live. This software can help you adjust fuel maps and ignition timing for better performance.
  • Wiring Harnesses: A quality wiring harness designed for LS swaps can simplify installation and ensure all components work seamlessly together.

Investing in the right ECU setup will lead to better performance, fuel efficiency, and reliability.

Suspension Upgrades for RX-8 LS Swap

Upgrading the suspension is crucial for handling the added weight and power of an LS engine. Here are some cost-effective suspension upgrades:

  • Coilovers: Adjustable coilovers can improve handling and allow for ride height adjustments. Brands like BC Racing and Fortune Auto offer affordable options.
  • Upgraded Sway Bars: Stiffer sway bars can reduce body roll and improve cornering stability. Look for options from companies like Eibach or Whiteline.
  • Performance Bushings: Replacing factory rubber bushings with polyurethane or solid options can enhance responsiveness and longevity.

These suspension upgrades will help you maintain control and stability, making your RX-8 a more enjoyable driving experience.

Conclusion

Upgrading your RX-8 with an LS swap can be a rewarding project, especially with the right supporting mods. By focusing on cost-effective clutch, ECU, and suspension upgrades, you can ensure your vehicle performs at its best while staying within budget. Always research and choose components that align with your performance goals and driving style.
