ESR SMX Engine

After years of dominance in the Spec Miata field, ESR is leveraging our extensive experience in building championship-winning cars and engines to excel in the Spec MX-5 series. Our inaugural Spec MX-5 car not only marked our entry into the series but also clinched the first championship title. While our engine features the same spec head as others in the series, we meticulously focus on every other detail to ensure superior performance. We construct each engine individually, maximizing every allowable area to enhance overall power and efficiency. Join us at the front! Vehicle Applications: 2006-2015 Mazda Miata MX-5 2.0L NC
