Optimizing Supporting Mods for Rx-8 Ls Swap: Cooling, Exhaust, and Drivetrain Upgrades

by

The RX-8 is a unique sports car known for its lightweight design and rotary engine. However, many enthusiasts are opting for an LS swap to enhance performance and reliability. This article will explore the essential supporting modifications needed for an RX-8 LS swap, focusing on cooling, exhaust, and drivetrain upgrades.

Cooling Upgrades

One of the critical aspects of an LS swap in the RX-8 is ensuring adequate cooling. The LS engine produces significantly more heat than the factory rotary engine, necessitating a more efficient cooling system.

  • Radiator Upgrade: Consider upgrading to a larger aluminum radiator to improve heat dissipation.
  • Cooling Fans: Install high-performance electric fans for better airflow and temperature control.
  • Thermostat: Use a lower temperature thermostat to help maintain optimal engine temperatures.
  • Hoses: Upgrade to high-performance silicone hoses for improved durability and heat resistance.

Exhaust Upgrades

The exhaust system plays a vital role in the performance of an LS engine. A well-designed exhaust system can improve horsepower and torque while enhancing the sound of the vehicle.

  • Headers: Install long-tube headers to reduce exhaust backpressure and increase flow.
  • Cat-Back Exhaust: Choose a high-flow cat-back exhaust system to enhance sound and performance.
  • High-Performance Catalytic Converters: Consider high-flow cats to improve exhaust flow while maintaining emissions compliance.

Drivetrain Upgrades

With the added power of an LS engine, it’s crucial to ensure that the drivetrain components can handle the increased torque and performance. Upgrading the drivetrain will help maintain reliability and improve driving dynamics.

  • Transmission Swap: Consider a T56 manual transmission for better performance and gear ratios.
  • Driveshaft: Upgrade to a stronger driveshaft to handle the additional power without failure.
  • Differential: Install a limited-slip differential to improve traction and handling during acceleration.
  • Clutch Upgrade: Use a high-performance clutch to handle the increased power and prevent slippage.

Conclusion

Optimizing supporting mods for an RX-8 LS swap is essential for achieving the best performance and reliability. By focusing on cooling, exhaust, and drivetrain upgrades, enthusiasts can create a powerful and enjoyable driving experience. Each component plays a vital role in ensuring that the LS engine operates efficiently and effectively within the RX-8 chassis.
