The Mazda RX-8 is a unique sports car known for its rotary engine and lightweight design. However, many enthusiasts opt for an LS swap to enhance performance and reliability. This article explores the best supporting modifications for an RX-8 LS swap, focusing on upgraded differentials, wideband gauges, and suspension enhancements.
Upgraded Differential
An upgraded differential is essential for handling the increased power from the LS engine. The stock RX-8 differential may struggle under the added torque, leading to potential failures. Here are some recommended options:
- Ford 8.8 Differential: A popular choice due to its strength and availability of aftermarket parts.
- GM 10-Bolt Differential: Offers a good balance of strength and weight, making it a viable option for many LS swaps.
- Wavetrac LSD: Provides excellent traction and handling, particularly in high-performance applications.
When selecting a differential, consider the gear ratio that best suits your driving style and intended use of the vehicle. A lower gear ratio can improve acceleration, while a higher ratio can enhance fuel efficiency on the highway.
Wideband Gauges
Monitoring the air-fuel ratio is crucial for optimizing performance and ensuring engine longevity. Wideband gauges provide real-time data, allowing you to fine-tune your engine’s performance. Here are some top choices:
- AEM Wideband UEGO: Known for its accuracy and reliability, this gauge is a favorite among tuners.
- Innovate Motorsports LC-2: Offers a comprehensive kit with a wideband sensor and gauge, making installation straightforward.
- PLX Devices SM-AFR: Features a digital display and can connect to multiple sensors for enhanced monitoring capabilities.
Installing a wideband gauge not only helps in tuning but also aids in diagnosing any issues that may arise during the LS swap process. It’s an investment that pays off in the long run.
Suspension Enhancements
With the added weight and power of an LS engine, upgrading the suspension is vital for maintaining handling and stability. Here are some recommended suspension enhancements:
- Coilover Kits: Brands like BC Racing and Fortune Auto offer adjustable coilovers that allow you to set the ride height and damping to your preference.
- Sway Bars: Upgraded sway bars can significantly reduce body roll, improving cornering performance.
- Strut Braces: Adding a front strut brace can enhance chassis stiffness, leading to better handling characteristics.
When upgrading the suspension, it’s important to consider the overall balance of the car. A well-tuned suspension will provide a more enjoyable driving experience and improve lap times on the track.
Conclusion
Upgrading your RX-8 with an LS engine is an exciting project that can yield impressive results. By focusing on supporting modifications like an upgraded differential, wideband gauges, and suspension enhancements, you can ensure that your vehicle performs at its best. Each of these components plays a crucial role in the overall performance and reliability of your LS-swapped RX-8.
Always consult with professionals or experienced builders when making significant modifications to your vehicle. With the right upgrades, your RX-8 can become a powerhouse on the road or track.
