The LS engine swap has become a popular modification for the Mazda Miata, particularly among enthusiasts looking to achieve high horsepower figures. For those aiming for a target of 550 horsepower, selecting the right camshaft and intake system is crucial. In this article, we will explore the best options available for camshafts and intake choices that can help you reach this ambitious goal.
Understanding the LS Engine and Its Potential
The LS engine, known for its lightweight design and robust power capabilities, is an excellent choice for a Miata build. With the right modifications, these engines can easily achieve and exceed 550 horsepower. However, to unlock this potential, specific components like camshafts and intake systems must be carefully selected.
Choosing the Right Camshaft
When selecting a camshaft for a 550 hp LS Miata build, it’s essential to consider the lift, duration, and lobe separation angle. These factors will significantly influence the engine’s performance characteristics.
Recommended Camshaft Options
- Texas Speed Stage 2 Camshaft: Offers a great balance of power and drivability, ideal for street and track use.
- Brian Tooley Racing (BTR) Stage 3 Camshaft: Designed for high horsepower builds, providing aggressive power gains at higher RPMs.
- Comp Cams XFI RPM Cam: Excellent for those looking to maximize the RPM range while maintaining reliability.
Intake System Choices
The intake system plays a vital role in ensuring that your LS engine breathes efficiently. A well-designed intake can significantly improve airflow, leading to better performance and horsepower gains.
Best Intake Options for 550 HP
- LS3 Intake Manifold: A popular choice for its excellent airflow characteristics and compatibility with various LS engines.
- Fast 102mm Intake Manifold: Known for its high flow capabilities, making it suitable for high horsepower builds.
- Holley Hi-Ram Intake: Ideal for those looking to maximize performance in a racing environment.
Combining Camshaft and Intake for Optimal Performance
For a 550 hp Miata LS build, it’s essential to ensure that your camshaft and intake work well together. The right combination can lead to significant improvements in horsepower and torque.
Matching Camshaft and Intake
- Texas Speed Stage 2 with LS3 Intake: This combination provides a solid balance of power and drivability.
- BTR Stage 3 with Fast 102mm Intake: Perfect for those seeking aggressive performance and high RPM power.
- Comp Cams XFI with Holley Hi-Ram: Best suited for dedicated track builds where maximum performance is required.
Additional Considerations
While camshaft and intake choices are critical, other components should also be considered to achieve optimal performance and reliability.
Supporting Modifications
- Exhaust System: A high-flow exhaust system is necessary to complement the intake and camshaft upgrades.
- Fuel System: Upgrading the fuel injectors and pump will ensure adequate fuel delivery for high horsepower levels.
- Tuning: Proper tuning is essential to maximize the performance gains from your camshaft and intake choices.
Conclusion
Achieving 550 horsepower in a Miata LS build requires careful selection of components, particularly the camshaft and intake system. By choosing the right options and ensuring they work well together, you can unlock the full potential of your engine. Remember to consider supporting modifications and proper tuning to achieve the best results.
