The Miata is known for its lightweight and nimble handling, making it a favorite among car enthusiasts. However, many seek to enhance its performance by swapping in a more powerful engine. The LS engine, known for its reliability and power, has become a popular choice for Miata enthusiasts. This article explores a cost-effective approach to performing an LS swap in a Miata, focusing on the use of auto cables and rebuilt LS engines.
Understanding the LS Engine
The LS engine family, developed by General Motors, is renowned for its performance and versatility. These engines are lightweight, compact, and offer a wide range of aftermarket support, making them ideal for swaps. Key advantages include:
- High power output
- Robust aftermarket support
- Lightweight design
- Relatively low cost for performance
Why Choose a Rebuilt LS Engine?
Opting for a rebuilt LS engine can significantly reduce costs while providing reliability. Here are some reasons to consider a rebuilt engine:
- Lower cost compared to new engines
- Potential for upgraded components
- Customization options available
- Environmental benefits of reusing parts
Using Auto Cables for the Swap
One of the most critical aspects of an LS swap is ensuring that the engine can be controlled effectively. Using auto cables is a cost-effective solution for throttle and shifter connections. Here’s how to implement this:
Throttle Cable Setup
When swapping an LS engine into a Miata, using a throttle cable from an automatic transmission vehicle can simplify the connection. This method can save both time and money. Key steps include:
- Identify a suitable throttle cable from a compatible vehicle.
- Modify the cable length if necessary.
- Ensure proper routing to avoid interference with other components.
Shifter Cable Connection
For the shifter, using an automatic shifter cable allows for smooth gear transitions. Here are the steps to follow:
- Choose a shifter cable that fits both the Miata and the LS transmission.
- Adjust the mounting points to ensure proper alignment.
- Test the shifter operation before finalizing the installation.
Additional Considerations for Your LS Swap
While the throttle and shifter cables are crucial, several other factors should be considered to ensure a successful LS swap:
- Cooling System: Upgrading the cooling system is essential to handle the increased heat from the LS engine.
- Fuel System: Ensure the fuel system can provide adequate pressure and volume for the LS engine.
- Electrical Wiring: Adapting the wiring harness to connect the LS engine to the Miata’s electrical system is necessary.
- Exhaust System: Custom exhaust may be required to fit the LS engine in the Miata’s chassis.
Budgeting Your LS Swap
One of the primary concerns for enthusiasts is budget. Here’s a breakdown of potential costs associated with an LS swap:
- Rebuilt LS Engine: $3,000 – $5,000
- Transmission: $1,000 – $2,500
- Throttle and Shifter Cables: $100 – $300
- Miscellaneous Parts (mounts, wiring, etc.): $500 – $1,000
- Labor (if not DIY): $1,000 – $2,000
Conclusion
Performing a cost-effective LS swap in a Miata can be an exciting project that enhances the car’s performance significantly. By using rebuilt LS engines and auto cables for connections, enthusiasts can save money while achieving impressive results. With careful planning and execution, your Miata can become a powerful and reliable machine that stands out on the road.
