does anyone know of any technical programs or seminars where people can pay to learn how to rebuild or repair 13b or 20b engines?

 

your best bet would be to contact Mazda or one of the larger shops with an official affiliation (RB, Mandeville, etc.). if a program exists, they would know.

if those avenues fail, then get a video (Aaron Cake on Youtube or you can buy a rebuild DVD) ... or find somewhere or someone that would be willing to allow you share some of their time to teach you.

 

go to the junk yards and tear apart rotary motors. best way to learn about a motor is by taking it apart.
