Description

The Monster Miata MM-V8-CONVERSION-KIT is a comprehensive package designed to enable the installation of a GM LS V8 engine into a Mazda Miata. This kit provides a foundation for the conversion, including components that address critical aspects of engine and drivetrain integration. Key parts included are Monster custom axles with plug-and-play spacers, an aluminum radiator with a steam fitting, and fans for cooling. The kit also features a clutch master cylinder, clutch hose fittings, and a clutch master cylinder adapter to manage the clutch system. Further components in the basic kit address other integration needs. These include front springs to handle the added weight, a speed o conversion box and a tach conversion box to adapt the Miata's instrumentation to the V8 engine, and a transmission cross member for proper drivetrain alignment. Additionally, the kit incorporates a differential hanger, radiator hangers, header, and sway bar mounts. Options such as full-length frame rails, a differential torque mount, a low-profile oil pan, a custom sub-frame, and engine mounts with urethane bushings are available as add-ons to further enhance the conversion. The listed price for the GM LS V8 Basic Kit is $6,190.00.
