This engine/transmission adapter plate allows you to bolt a K24 engine to any 2006-2015 Mazda MX5 transmission (5 and 6-speed).  

Unlike other adapter plates, ours are machined out of precision-ground 0.500” steel plate. By using steel instead of aluminum, our adapters are as thin as possible without compromising rigidity or thread strength. 

Our plate design ensures that no additional flywheel mass is needed due to an overly thick plate, and the steel threads can withstand a lifetime of engine and transmission service. 

All plates are machined in-house and individually test fitted and deburred before being zinc plated. All of the required high-grade metric hardware is included, as one OEM Mazda dowel and custom machined stepped dowel.
