Overview

The V8 Roadsters NA & NB LSx Package is an all-inclusive conversion kit designed to simplify the process of swapping an LS engine into a Mazda NA or NB Miata. This bundle provides the core structural, drivetrain, and fueling components required to facilitate the swap.

Customers must supply their own engine, transmission, and differential to complete the conversion. The package includes items such as a mounting kit, driveline kit, clutch kit, oil pan, long tube headers, and fuel system components.
Show original supplier description
The V8 Roadsters NA & NB LSx Package is a comprehensive conversion bundle engineered to help builders integrate an LS engine into their NA or NB Mazda Miata. By grouping essential hardware together, this kit removes the complexity of sourcing individual parts, though it is intended for builders who can supply the major drivetrain components themselves—specifically the engine, transmission, and differential. Key components in this kit include an LSx mounting kit (G1-G3), driveline kit, clutch kit, aluminum oil pan, long tube headers, LSx fuel kit, frame rail reinforcements, HD sway bar mounts, a power steering kit, and a steel driveshaft. The driveshaft can be upgraded to aluminum or carbon fiber, and the package is built to order to accommodate specific build requirements. Installers should note that several items are NOT included in the package, such as cooling systems, coolant hoses, hose clamps, and down pipe-back exhaust, which must be purchased separately. The included headers are designed specifically for LHD models and will require modification to be compatible with RHD vehicles. Additionally, while the power steering kit is included, the lines provided are not compatible with RHD configurations and must be fabricated locally. Lead times for these custom-built kits vary, and components may arrive in separate shipments. Builders are advised to contact the manufacturer for current delivery estimates before commencing their project.
