The NC Miata is a beloved sports car known for its lightweight design and agile handling. One of the most popular modifications among enthusiasts is the installation of aftermarket camshafts. But are these upgrades worth the investment? In this article, we will explore the performance benefits and costs associated with aftermarket camshafts for the NC Miata.
Understanding Camshafts
Before diving into the specifics of aftermarket camshafts, it’s essential to understand what a camshaft does. The camshaft controls the timing and duration of the engine’s intake and exhaust valves. By modifying the camshaft, you can alter the engine’s performance characteristics, potentially increasing horsepower and torque.
Benefits of Aftermarket Camshafts
Aftermarket camshafts can provide several advantages over stock components. Here are some key benefits:
- Increased Power: Aftermarket camshafts can enhance horsepower and torque by optimizing valve timing.
- Improved Engine Response: A performance camshaft can lead to quicker throttle response and better overall drivability.
- Customization: Different cam profiles allow for tailored performance based on driving style and preferences.
- Enhanced Sound: Many enthusiasts appreciate the more aggressive engine sound that comes with aftermarket camshafts.
Types of Aftermarket Camshafts
When considering aftermarket camshafts, it’s crucial to understand the different types available:
- Stage 1 Camshafts: Designed for mild performance improvements, these are ideal for daily drivers.
- Stage 2 Camshafts: Offer more significant performance gains, suitable for spirited driving and occasional track use.
- Stage 3 Camshafts: Provide maximum performance but may sacrifice drivability for track-focused applications.
Performance Gains
The performance gains from aftermarket camshafts can vary based on the specific cam profile and supporting modifications. Here’s a general idea of what to expect:
- Stage 1: Typically yields a 5-10% increase in horsepower.
- Stage 2: Can provide a 10-20% increase in horsepower, depending on other modifications.
- Stage 3: May produce a 20% or more increase, but often requires additional tuning and supporting mods.
Cost Considerations
When evaluating whether aftermarket camshafts are worth it, cost is a significant factor. Here’s a breakdown of potential expenses:
- Camshaft Cost: Aftermarket camshafts typically range from $300 to $1,200, depending on the brand and performance level.
- Installation: Professional installation can cost between $300 and $600, depending on labor rates and shop expertise.
- Tuning: Proper tuning is essential for maximizing performance, costing an additional $300 to $800.
Potential Drawbacks
While aftermarket camshafts offer numerous benefits, there are some drawbacks to consider:
- Cost: The total investment can be significant, especially when factoring in installation and tuning.
- Drivability: Some performance camshafts may reduce low-end torque, affecting daily driving comfort.
- Reliability: Depending on the quality of the camshaft and installation, there may be risks of engine damage if not done correctly.
Conclusion
Aftermarket camshafts can be a worthwhile investment for NC Miata owners looking to enhance performance. With the potential for increased horsepower, improved throttle response, and customization options, these upgrades can significantly elevate your driving experience. However, it’s essential to weigh the costs and potential drawbacks before making a decision. As always, ensuring proper installation and tuning will be critical to achieving the desired results.
