Enhance your driving experience with the MGA 5-Speed Conversion kit! Built on the reliable and proven Mazda MX-5 gearbox, this conversion kit offers smooth gear shifts and a relaxed cruising 5th gear for your MGA. Made with top-quality components, each kit includes a fully assembled gearbox with a custom-cast bell housing and casing, designed to fit directly onto the MGA’s engine back plate. The bell housing flange mirrors the standard gearbox to maintain the original look of the engine bay. The kit uses the appropriate flywheel for your engine, a compatible clutch cover, and a Mazda OE clutch plate.

Installation is relatively straightforward but requires removing the existing gearbox mounts and enlarging the gearbox tunnel opening. Detailed modification instructions are included. The MGA 5-Speed Conversion by Vitesse is designed for all MGA models, including the 1800 conversions. Choose your kit and enjoy the ultimate upgrade for your MGA, enhancing your driving experience while maintaining the historic character you love.
