I'm looking for a 12A core motor for a 1st generation Rx7. I'm looking to rebuild it so i'm curious what parts are needed to be replaced to make a new good strong motor. If there are any links you guys can link me to, to inform me on what it takes to rebuild it that would be outstanding. Also if anyone is selling an old motor, lemme know of my options because i'm looking to rebuild one for my 7

I hate to do this mazdaverx713b, but from what i understand that is one of the pricy repairs. Look also in the 1st gen parts for sale forum.

iwill sell you a RUNNING 12a , runs strong too, just has a dowell pin leak, so it would be a great canidate for a rebuild

During almost any rebuild i would recommend replacing the apex seals (unless a very low mileage motor). So if you buy a motor w/ the intent of doing a rebuild...you might as well get a deal on a blown one. That is just my opinion though.

Yeah but the thing is... if it has a blow apex-seal then there's a good chance it may have taken out the rotor-housing, rotor or even both the side plates. Whereas with a running engine you can often reuse these parts.

Is there a website where it describes this motor in detail? I'm looking for rebuilding information, such as what parts to replace yadda yadda yadda

I have a 82' 12a with only 70k original miles, no leaks, sitting on my garage floor. I may already have a buyer....but I'm not sure yet.

Have you read the secion in the Haynes manyal for the first gen rx7. It as a pretty good break down how to do the rebuild.

I got a couple of 12a'a 3 actually if your interested. One for sure has around 65k with amazing compression. The other has 120k. I'm not sure about the other one though. Just pm me for more details.

Sure, engine paint will work fine except on the exhaust. But you have to make sure its good and clean first.
