Man that is a great list of all the compiled special Eunos'! I can help you fill in some blanks however. According too the previous and original owner of my B-Spec who was a Mazda Tech in Japan says that there were only 25 B-Spec 2's officially built by Mazdaspeed and the rest were sold as the optional kit that was advertised in magazines. Also I have heard that there are 100 B-Specs with the Non-Supercharger package aka the B-Spec 1.
Also little fact for everyone my car was built off an S-Special chassis.
