The Miata, known for its lightweight and agile handling, has become a popular platform for engine swaps, particularly the LS swap. This article explores the 0-60 mph times of Miatas with stock engines compared to those equipped with 500+ horsepower LS setups. Understanding these performance metrics can help enthusiasts make informed decisions about modifications and upgrades.
Understanding the Miata LS Swap
The LS engine swap involves replacing the original Miata engine with a General Motors LS series engine. This swap is favored for its power potential, weight-to-power ratio, and aftermarket support. The process requires modifications to the engine bay, transmission, and sometimes the rear differential.
Stock Miata Performance
Stock Miatas, depending on the model year, typically come equipped with inline-4 engines producing around 90 to 140 horsepower. The 0-60 mph times for these models can vary, but they generally fall within the following ranges:
- NA Miata (1990-1997): 0-60 mph in approximately 8.0-9.0 seconds
- NB Miata (1999-2005): 0-60 mph in approximately 7.0-8.0 seconds
- NC Miata (2006-2015): 0-60 mph in approximately 6.0-7.0 seconds
- ND Miata (2016-present): 0-60 mph in approximately 5.5-6.5 seconds
500+ HP LS Swaps
Swapping in an LS engine can significantly increase the power output of a Miata, often exceeding 500 horsepower. This boost in power dramatically affects acceleration times. Below are some examples of 0-60 mph times for Miatas with 500+ hp LS setups:
- LS1 Miata (500 hp): 0-60 mph in approximately 3.5-4.0 seconds
- LS3 Miata (550 hp): 0-60 mph in approximately 3.0-3.5 seconds
- LS7 Miata (600 hp): 0-60 mph in approximately 2.8-3.2 seconds
- Supercharged LS Miata (700 hp): 0-60 mph in approximately 2.5-3.0 seconds
Factors Influencing 0-60 Times
Several factors can influence the 0-60 mph times of both stock and LS-swapped Miatas, including:
- Weight of the vehicle
- Type of tires and grip
- Transmission type and gearing
- Driver skill and launch technique
- Road conditions and surface
Comparative Analysis
To better understand the performance differences, here’s a comparative analysis of stock vs. LS-swapped Miatas based on their 0-60 mph times:
- Stock Miata (NA): 8.5 seconds vs. LS1 Miata: 3.5 seconds
- Stock Miata (NB): 7.5 seconds vs. LS3 Miata: 3.0 seconds
- Stock Miata (NC): 6.5 seconds vs. LS7 Miata: 2.8 seconds
- Stock Miata (ND): 6.0 seconds vs. Supercharged LS Miata: 2.5 seconds
Conclusion
The LS swap has proven to be a transformative upgrade for the Miata, providing significant performance gains in acceleration. While stock Miatas offer a fun and engaging driving experience, the addition of a 500+ hp LS engine can catapult the vehicle into a different performance league altogether. Enthusiasts should weigh the benefits of such modifications against their driving goals and the associated costs.
