ND Miata has existed for ten years, but how can Mazda realistically enhance it? Current automotive trends—from large-screen technology to electric powertrains—are at odds with the Miata’s principle of simplicity. While Mazda might be constrained by new-car buyer expectations and regulatory requirements, the aftermarket remains unrestricted.
Like the earlier generations, the ND is a superb platform for modifications, and one of the most impressive builds we’ve encountered comes from Geaux Moto. Located in Louisiana, the company offers a 2.3-liter Ford EcoBoost swap kit for the ND. Naturally, Geaux Moto doesn’t keep that larger turbocharged inline-four—used in vehicles like the Mustang and the latest Focus RS—stock. They also pair the enhanced engine with serious aerodynamics.
According to a video on the company’s YouTube channel, this vehicle features a larger twin-scroll Garrett turbo with dual wastegates, achieving 460 horsepower and 393 pound-feet of torque on the dyno (Geaux Moto’s demo car reportedly makes 450 hp at the wheels). The customer requested a setup that was reasonable enough for street use, so its standard tune is 321 hp and 378 lb-ft. It utilizes a Focus RS oil pan with additional baffling, complemented by a larger radiator, intercooler, and extra radiators nestled in the factory foglamp housings to manage cooling requirements.
Geaux Moto employs the Mustang’s MT-82 six-speed manual transmission, which is actually the most intricate aspect of the swap. Installing the engine necessitates minor trimming around the cowl and relocating some accessories, but integrating a non-stock transmission calls for an alternative to the Power Plant Frame, the structural element that connects the transmission to the rear differential instead of a typical transverse crossmember. Behind the gearbox lies an OS Giken limited-slip differential housed in the robust stock casing.

Another remarkable feature of this Miata is the Varis-engineered aerodynamic kit. Geaux Moto acquires the substantial rear wing and fabricates the carbon-fiber front splitter in-house to Varis specifications. This setup generates 576 pounds of downforce at 100 mph. Coupled with 285/30ZR17 tires at both ends, it ensures the Miata remains stable while delivering nearly double the power of a stock ND.
This vehicle is anything but a casual cruiser, yet it maintains air conditioning and most of its interior, integrating stock elements with Sparco seats and a custom roll bar designed to fit under the DG hardtop. The result is an impressively well-engineered vehicle that demonstrates the potential of the ND chassis.
**Ford EcoBoost-Powered Miata: A Leading Contender in Modified Sports Cars**
The Mazda Miata, celebrated for its lightweight construction, nimble handling, and classic roadster charm, has long captivated car enthusiasts and tuners alike. However, a novel trend has emerged in recent years that elevates the beloved Miata to an entirely new realm: the incorporation of Ford’s EcoBoost engine. This fusion has stirred interest and enthusiasm within the modified sports car community, establishing the EcoBoost-powered Miata as a formidable competitor in the performance vehicle landscape.
**The EcoBoost Engine: A Quick Overview**
Ford’s EcoBoost technology signifies a considerable leap in engine design, emphasizing turbocharging and direct fuel injection to boost performance while enhancing fuel efficiency. The EcoBoost engines, especially the 2.0-liter and 2.3-liter variants, are recognized for their exceptional power output and torque performance, making them ideal selections for a lightweight sports car like the Miata. With the capacity to generate over 250 horsepower and impressive torque, the EcoBoost engine revolutionizes the Miata’s driving experience, delivering excitement that rivals that of more robust sports cars.
**The Advantages of Swapping the Miata’s Engine**
1. **Power-to-Weight Ratio**: One of the Miata’s signature features is its light weight, usually around 2,300 pounds. By replacing the factory engine with an EcoBoost variant, enthusiasts can achieve a remarkable power-to-weight ratio, boosting acceleration and overall performance.
2. **Enhanced Torque Delivery**: The turbocharged nature of the EcoBoost engine ensures a broad torque range, providing improved responsiveness and acceleration at lower RPMs. This trait proves particularly advantageous for a lightweight vehicle, making it feel even more agile and spirited on the road or track.
3. **Tuning Opportunities**: The EcoBoost engines exhibit significant tuning potential, with a vast array of aftermarket support available. This broadens possibilities for additional modifications, such as enhanced turbos, intercoolers, and exhaust systems, allowing enthusiasts to elevate their Miatas to unprecedented performance levels.
4. **Fuel Efficiency**: Despite the surge in power, EcoBoost engines are crafted for fuel efficiency. Consequently, modified Miatas can deliver exhilarating performance without compromising daily drivability or incurring excessive fuel expenses.
**Challenges of the Swap**
While the advantages are enticing, the endeavor of swapping a Ford EcoBoost engine into a Miata does come with its hurdles. Custom fabrication may be needed for engine mounts, transmission compatibility, and exhaust routing. Additionally, tuning the engine management system to seamlessly integrate with the Miata’s electronics can be intricate. Enthusiasts must also take into account the weight distribution and balance of the car, as introducing a heavier engine can impact handling characteristics.
**Community and Culture**
The EcoBoost-powered Miata has cultivated a devoted following within the automotive community. Online forums, social media platforms, and local car gatherings are populated with enthusiasts sharing their experiences, advice, and modifications. This sense of community promotes a culture of innovation, with builders pushing the boundaries of what a modified Miata can accomplish.
**Conclusion**
The Ford EcoBoost-powered Miata exemplifies the creativity and ingenuity of automotive enthusiasts. By fusing the lightweight allure of the Miata with the robust performance of Ford’s EcoBoost technology, this modified sports car not only augments driving joy but also challenges the traditional norms of performance vehicles. As more enthusiasts embark on this journey, the EcoBoost Miata is set to establish itself as a leading contender in the modified sports car arena, providing a unique mix of power, efficiency, and driving exhilaration.
