The Mazda FD RX-7 is a beloved sports car that has captured the hearts of enthusiasts since its debut. With its lightweight body and rotary engine, the RX-7 is known for its agility and performance. However, many owners seek to enhance their driving experience by increasing horsepower. This article explores the top five power gains achievable with turbo upgrades from renowned manufacturers like Garrett and Precision, potentially boosting your RX-7’s horsepower by up to 50%.
1. Turbocharger Upgrades
Upgrading to a high-performance turbocharger is one of the most effective ways to increase horsepower in the FD RX-7. Both Garrett and Precision offer turbo options that can significantly enhance the engine’s output.
- Garrett GTX2860R: This turbo provides quick spool times and excellent power delivery, making it a popular choice for street and track use.
- Precision 6266: Known for its ability to support high horsepower levels, the Precision 6266 can deliver exceptional performance for serious racers.
2. Upgraded Intercooler
A high-performance intercooler is essential for maintaining optimal air intake temperatures, which is crucial when running higher boost levels. An upgraded intercooler can help reduce heat soak and improve overall efficiency.
- Garrett Front Mount Intercooler: This intercooler is designed for maximum airflow and cooling efficiency, ensuring your engine runs at optimal temperatures.
- Precision Intercooler Kit: Tailored specifically for the RX-7, this kit provides a direct fit and enhances performance without compromising reliability.
3. Exhaust System Enhancements
Upgrading the exhaust system is another vital step in maximizing horsepower. A performance exhaust system reduces back pressure, allowing the engine to breathe more freely and produce more power.
- Garrett Turbo Back Exhaust: This system is designed to optimize flow and reduce restrictions, providing a noticeable increase in horsepower.
- Precision Cat-Back Exhaust: With a focus on performance and sound, this exhaust system enhances both power and the driving experience.
4. Engine Management System
A proper engine management system is crucial for tuning the RX-7 after installing new turbochargers and supporting modifications. A standalone ECU or a reflash can optimize fuel maps and ignition timing for maximum performance.
- Haltech Elite Series: This advanced ECU allows for comprehensive tuning options, ensuring your RX-7 runs efficiently with upgraded components.
- AEM Infinity: Known for its flexibility and performance, the AEM Infinity system provides precise control over engine parameters.
5. Supporting Modifications
To truly maximize the potential of your FD RX-7, consider additional supporting modifications. These can include upgraded fuel injectors, fuel pumps, and intake systems, all of which contribute to improved performance.
- Upgraded Fuel Injectors: Larger injectors can supply the necessary fuel for increased horsepower, ensuring your engine runs smoothly under boost.
- High-Performance Fuel Pump: A reliable fuel pump is essential for maintaining proper fuel pressure during high-demand situations.
- Cold Air Intake Systems: An aftermarket intake can improve airflow to the engine, enhancing throttle response and overall performance.
By implementing these upgrades, FD RX-7 owners can experience significant power gains, transforming their vehicle into a high-performance machine. With the right combination of turbochargers, intercoolers, exhaust systems, and supporting modifications, achieving up to 50% more horsepower is within reach.
