The world of automotive performance has seen a significant rise in the popularity of engine swaps, particularly the LS and Coyote swaps. These swaps have become a common choice for enthusiasts looking to enhance their vehicle’s performance. In this article, we will explore a reliability test conducted over 100,000 miles on LS vs Coyote swaps, specifically using Bilstein shocks and a Stage 3 tune.
Overview of Engine Swaps
Engine swaps involve replacing a vehicle’s original engine with a different one, often to improve power, efficiency, or reliability. The LS engine, a product of General Motors, is known for its lightweight design and high performance. The Ford Coyote engine, on the other hand, is celebrated for its modern technology and robust performance capabilities. Both engines have their unique advantages and drawbacks.
Testing Parameters
For this reliability test, we focused on several key parameters that would provide a comprehensive evaluation of both engine swaps. The parameters included:
- Engine performance
- Fuel efficiency
- Durability under stress
- Compatibility with Bilstein shocks
- Response to Stage 3 tuning
Engine Performance
Performance is a critical aspect of any engine swap. The LS engine is renowned for its ability to produce substantial horsepower and torque with relatively simple modifications. In contrast, the Coyote engine offers advanced features such as variable valve timing and direct fuel injection, which enhance its performance capabilities.
LS Engine Performance
The LS engine’s performance was tested on a variety of terrains and conditions. The results showed that the LS engine consistently delivered impressive acceleration and responsiveness. With the addition of a Stage 3 tune, the engine was able to reach its peak performance, providing a thrilling driving experience.
Coyote Engine Performance
The Coyote engine also demonstrated remarkable performance, particularly in terms of throttle response and high-rev capabilities. The Stage 3 tune further optimized its performance, allowing for smooth power delivery and improved overall driving dynamics.
Fuel Efficiency
Fuel efficiency is another important factor to consider when evaluating engine swaps. Both engines were monitored for fuel consumption over the 100,000 miles.
LS Engine Fuel Efficiency
The LS engine showcased decent fuel efficiency, especially considering its performance capabilities. On average, the LS engine achieved approximately 20 miles per gallon, which is respectable for a performance engine.
Coyote Engine Fuel Efficiency
The Coyote engine excelled in terms of fuel efficiency, averaging about 22 miles per gallon. Its advanced technology contributed to better fuel management, making it a more economical choice for daily driving.
Durability Under Stress
Durability is crucial for any engine swap, especially when subjected to rigorous driving conditions. Both engines were put through a series of stress tests to evaluate their resilience.
LS Engine Durability
The LS engine performed admirably under stress, showing minimal signs of wear after the extensive testing. Components such as the intake and exhaust systems held up well, and the engine maintained consistent performance throughout.
Coyote Engine Durability
The Coyote engine also demonstrated strong durability, withstanding high RPMs and aggressive driving without any significant issues. Its build quality and engineering proved to be effective in maintaining reliability over long distances.
Compatibility with Bilstein Shocks
Bilstein shocks are renowned for their performance and reliability, making them a popular choice for modified vehicles. Both engine swaps were assessed for compatibility with Bilstein shocks, focusing on ride quality and handling.
LS Swap with Bilstein Shocks
The LS swap paired with Bilstein shocks provided an exceptional balance of comfort and performance. The shocks effectively absorbed bumps and improved overall handling, making for an enjoyable driving experience.
Coyote Swap with Bilstein Shocks
The Coyote swap also benefited from the Bilstein shocks, offering enhanced stability and control. The combination allowed for precise handling, especially during cornering and high-speed maneuvers.
Response to Stage 3 Tuning
Stage 3 tuning plays a significant role in maximizing the potential of both engine swaps. This section examines how each engine responded to the tuning process.
LS Engine Stage 3 Tune
The LS engine responded exceptionally well to the Stage 3 tune, with noticeable increases in horsepower and torque. The tuning process optimized fuel delivery and ignition timing, resulting in a more aggressive performance profile.
Coyote Engine Stage 3 Tune
Similarly, the Coyote engine exhibited significant gains from the Stage 3 tune. Enhanced throttle response and improved power output were evident, making the driving experience even more exhilarating.
Conclusion
After conducting a comprehensive reliability test over 100,000 miles, both the LS and Coyote swaps demonstrated their strengths and weaknesses. The LS engine offered robust performance and durability, while the Coyote engine excelled in fuel efficiency and advanced technology. Ultimately, the choice between the two engines will depend on personal preferences and driving styles.
Final Thoughts
Whether you choose an LS or Coyote swap, both options can provide thrilling performance when paired with quality components like Bilstein shocks and proper tuning. Understanding the characteristics of each engine will help enthusiasts make informed decisions for their projects.
