Engine building threads?
 

I am having a hard time navigating the site. I am searching for a how to build the 12a type thread. I have found lots of people who built it and are installing it, but nothing that is a write up on how to put one together. Is there a good write up for this on here I am missing?

there is no actual "how to" on the forum. if u search youtube there is a build vid from one of the rotary shops. it's probably a 13b build but the build process is virtually the same for the 12a as far as how they go together.

Not sure about the earlier series, but the Factory Service Manual is pretty comprehensive for the FD. And yours is probably available for free download here——>Mazda RX-7 Reference Materials
