This engine/transmission adapter plate allows you to bolt a K24 engine to any 2016-2025 Mazda Miata MX5 (ND) transmission. 

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.

Combine this with our KPower K Series to 2016-2025 Mazda Miata MX5 (ND) Lightweight Flywheel, a clutch of your choosing from our Clutch Collections page, a set of J35 Flywheel bolts, and you are all set to run a ND transmission on a K series engine.

Notes:

• 2019-2025 Mazda Miata (ND2 ND3) dual mass flywheel transmissions need to be converted to single mass utilizing the ND1 Front Clutch Cover Conversion
