The RX-7 has long been celebrated for its lightweight chassis and exceptional handling. When paired with an LS engine, it transforms into a formidable machine. However, to maximize the potential of your LS swap, consider cost-effective supporting mods that can significantly boost power without breaking the bank.
Understanding the LS Swap
The LS engine series, known for its robust performance and reliability, is a popular choice for RX-7 enthusiasts looking to enhance their vehicle’s power. However, simply swapping in an LS engine isn’t enough. Supporting modifications are necessary to unlock the full potential of the swap.
Essential Supporting Mods
- Cold Air Intake: Enhances airflow to the engine, improving combustion efficiency.
- Headers: Upgrading to long-tube headers can significantly reduce exhaust back pressure.
- High-Performance Exhaust System: A less restrictive exhaust system allows for better airflow, increasing power output.
- ECU Tune: Optimizing the engine’s computer can lead to significant power gains by adjusting fuel maps and timing.
- Upgraded Fuel Pump: Ensures adequate fuel delivery to support higher power levels.
Cold Air Intake
A cold air intake is one of the most cost-effective mods for your LS swap. By drawing cooler air from outside the engine bay, it improves the engine’s overall performance. Many aftermarket options are available, and installation is usually straightforward.
Headers
Upgrading to long-tube headers can provide substantial power gains by improving exhaust flow. They reduce back pressure and allow the engine to breathe more freely. While there are many options on the market, choosing a reputable brand can ensure quality and performance.
High-Performance Exhaust System
A high-performance exhaust system is crucial for maximizing the power of your LS engine. A less restrictive system can enhance exhaust flow, leading to improved throttle response and horsepower. Look for options that provide a good balance of sound and performance.
ECU Tune
After making modifications, an ECU tune is essential to ensure your engine runs efficiently. A proper tune can adjust fuel mixtures, ignition timing, and other parameters to optimize performance. Many tuners offer packages specifically for LS swaps, making this process easier.
Upgraded Fuel Pump
As you increase the power of your LS engine, you may need to upgrade your fuel pump to ensure adequate fuel delivery. An upgraded pump can support higher horsepower levels and prevent fuel starvation during high-demand situations.
Additional Considerations
- Cooling System: Ensure your cooling system can handle the increased power and heat.
- Transmission: Consider upgrading your transmission to handle the additional torque.
- Suspension Upgrades: Improved suspension components can help manage the additional power effectively.
Conclusion
Boosting power in your RX-7 LS swap doesn’t have to be expensive. By focusing on these cost-effective supporting mods, you can enhance performance and enjoy the full potential of your build. Always consider your goals and budget when planning modifications to ensure a successful and enjoyable project.
