Top Supporting Mods for Rx-7 Ls Swap: Cooling, Exhaust, and Suspension Upgrades

by

The RX-7 is a beloved platform for car enthusiasts, especially those looking to swap in a powerful LS engine. However, to ensure optimal performance and reliability, several supporting modifications are essential. This article will cover the top mods for cooling, exhaust, and suspension upgrades for an RX-7 LS swap.

Cooling Upgrades

When swapping an LS engine into an RX-7, managing heat is crucial. The LS engines produce significantly more heat than the original rotary engines, so upgrading the cooling system is a priority.

  • Aftermarket Radiator: A high-performance aluminum radiator can greatly improve cooling efficiency.
  • Cooling Fans: Upgrading to electric fans can provide better airflow and reduce engine bay temperatures.
  • Oil Cooler: An oil cooler helps maintain optimal oil temperatures, which is critical for engine longevity.
  • Upgraded Water Pump: A high-flow water pump ensures better coolant circulation throughout the engine.

Exhaust Upgrades

To maximize the performance of the LS engine, an efficient exhaust system is essential. Upgrading the exhaust not only improves power but also enhances the sound of the vehicle.

  • Long Tube Headers: These provide better exhaust flow compared to stock manifolds, resulting in increased horsepower.
  • High-Performance Catalytic Converters: Upgrading to high-flow cats can improve exhaust flow without sacrificing emissions compliance.
  • Cat-Back Exhaust System: A quality cat-back system can enhance sound and performance by reducing back pressure.
  • Exhaust Tips: Stylish exhaust tips can improve aesthetics while ensuring optimal exhaust flow.

Suspension Upgrades

A proper suspension setup is vital for handling the increased power and weight of an LS-swapped RX-7. Upgrading the suspension helps maintain vehicle stability and improves overall driving experience.

  • Coilovers: Adjustable coilovers allow for ride height and damping adjustments, enhancing handling performance.
  • Anti-Roll Bars: Upgrading sway bars reduces body roll during cornering, improving stability.
  • Upgraded Bushings: Performance bushings can improve steering response and reduce flex in the suspension components.
  • Strut Braces: Adding strut braces can enhance chassis rigidity, resulting in better handling characteristics.

In conclusion, supporting modifications for an RX-7 LS swap are crucial for ensuring that the vehicle performs at its best. By focusing on cooling, exhaust, and suspension upgrades, enthusiasts can enjoy a reliable and exhilarating driving experience.
