83-85 12A Engine Numbers
Main Engine Page | Home Page
These are the Part Numbers for 83-85 12A Engines. These are just the majority of the ones we list. We are able to "build" about any combination possible with our computer -- just give us specific requests, and we can come up with a pretty exact estimate of the cost.
The "Build Level" chart is at the bottom of the page
Note: Core supply is variable, please call prior to ordering your engine.
For 83-85 12A engines the cost of a full gasket set is included in the price of the engine. We use the gaskets/seals needed to assemble the engine, and send the remaining ones with the engine - that way you have essentially all the gaskets needed to finish the installation.
Mazda no longer sells any 12a rotor housings. This means that the "B" through "F" engines can not be built. Call for specific information if you need a quality 12A engine built with new rotor housings!
