Injectors
i was just wondering what size the o-rings are on the stock injectors of a 13b from 86. My injectors are leaking and someone suggested I replace the o-rings before doing anything else. Sizes for the primary and secondary injectors would be much appreciated!

Just my $0.02 worth, I'd get the replacement o-rings and rubber grommets straight from mazda or one of the vendors that DC5Daniel said. I have had the injector o-ring kits from oreillys (or autozone or one of those) leak and spray fuel everywhere after installation. Luckily I wasnt running the engine, just pressurizing the rail. They are close in size, but off just a little.

When I buy a used RX-7 I just send the injectors out for "rebuilding" and flow testing. That way I don't have to deal with piecing together the right parts, I can match the injectors if I wish, and it also tells me if the injectors will likely last for a few more years. It would suck to just replace the o-rings and then have the engine blow due to a dirty screen or otherwise failed injector.
