The automotive world is filled with enthusiasts who constantly seek to maximize performance while keeping costs manageable. One popular debate among Mazda Miata owners is whether to perform an LS swap or to turbocharge the existing 1.8L engine. This article aims to compare the costs and power outputs of both options, providing insights for those considering these modifications.
Understanding the LS Swap
The LS swap involves replacing the Miata’s original engine with a Chevrolet LS series engine. This swap has gained popularity due to the LS engine’s robust power potential and availability. However, it’s essential to consider the costs associated with this modification.
Cost Breakdown of an LS Swap
- LS Engine Cost: $3,000 – $8,000 depending on the model and condition.
- Transmission: $1,000 – $2,500 for a compatible transmission.
- Engine Mounts and Adapters: $500 – $1,000.
- Wiring Harness: $300 – $800.
- Cooling System Upgrades: $500 – $1,500.
- Miscellaneous Parts: $500 – $1,000 (exhaust, fuel system, etc.).
In total, the LS swap can range from approximately $6,300 to $14,800, depending on various factors such as labor costs and additional modifications.
Power Output of the LS Swap
One of the main attractions of the LS swap is the significant power increase. Depending on the specific LS engine chosen, power outputs can range from:
- LS1: Approximately 300 hp.
- LS3: Approximately 430 hp.
- LS7: Approximately 505 hp.
This power increase transforms the Miata into a serious performance machine, often leading to a thrilling driving experience.
Exploring the Turbocharged 1.8L Build
Turbocharging the existing 1.8L engine is another popular option among Miata enthusiasts. This method allows for significant power increases while maintaining the original engine’s character. However, it also comes with its own set of costs and considerations.
Cost Breakdown of Turbocharging
- Turbo Kit: $1,500 – $4,000 depending on brand and components.
- Fuel Management System: $300 – $1,000.
- Upgraded Fuel Injectors: $200 – $600.
- Intercooler and Piping: $300 – $800.
- Exhaust System Modifications: $200 – $500.
- Miscellaneous Parts: $200 – $500 (gaskets, oil lines, etc.).
The total cost for a turbocharged 1.8L build can range from approximately $2,900 to $7,400, making it a more budget-friendly option compared to the LS swap.
Power Output of the Turbocharged 1.8L Build
Turbocharging the 1.8L engine can yield impressive power figures, typically resulting in:
- Stock 1.8L: Approximately 130 hp.
- With Turbo: Approximately 200 – 300 hp, depending on boost levels and tuning.
While the turbocharged setup may not match the highest outputs of an LS swap, it offers a significant boost in performance while retaining the original engine’s lightweight characteristics.
Comparing the Two Options
When deciding between an LS swap and a turbocharged 1.8L build, several factors should be considered:
- Cost: Turbocharging is generally more affordable than an LS swap.
- Power Potential: The LS swap offers higher power outputs, especially with higher-end engines.
- Weight Distribution: The 1.8L maintains a better weight distribution, enhancing handling.
- Complexity: The LS swap is more complex and may require more custom fabrication.
- Driving Experience: Many enthusiasts prefer the character of the original engine with a turbo.
Ultimately, the choice between an LS swap and a turbocharged 1.8L build comes down to personal preference, budget, and desired driving experience.
Conclusion
Both the LS swap and turbocharging the 1.8L engine offer unique advantages and challenges. The LS swap provides significant power but at a higher cost and complexity, while turbocharging offers a more budget-friendly route with impressive performance gains. Enthusiasts should weigh their options carefully, considering their goals and resources, to choose the best path for their Miata.
