Im rebuilding my 13b on the 22nd so that i can bridge port it. Thus i bought the shop manual from mazda (1990). Just wanted to say that if any one needs a few pages out of it i can scan them and send them to you. However unlike the one Atkins sells i didn't get section Z the wirering diagrame section, so im no help there. So just PM me if you need any thing and I'll try to send you what u need when i can. and if anyone is thinking of getting a official shop manual i would sugest you take a look at what atkins rotary has, mine took about a month to come in, its was about the same price but like i said i didn't get the wiring diagram section its another 80 at mazda, and ontario mazda doesnt give us the 20% off on text material.
