it refers to the wieght, did the rotors come out of the same engine? if so, did they both come from an engine that was last built by Mazda? A 13b rotor is not just any 13b rotor. Those letters are very important. Your letters should match if you want the engine to be balanced. (You do.) And also, make sure you have the correct counterweight to match those rotors, and flywheel too.

I dented one of the rotors that matched so I'm trying to find another. But i cant match it unless i figure out which letter to use on the rotor.

This was recently discussed in another thread.
The "E" is more likely the Japanese katakana "yo".

There was a post on here a couple of years ago where someone emailed either Atkins Rotary or Mazdatrix and asked this same question. The answer was that the rotors are not perfectly balanced and that they were all stamped "A" through "E" to show where each rotor fell in the range of "perfect" and "least tolerable". As long as the two rotors in an engine were within two letters of each other, they could be used together. Example is a "A" rotor and a "B" or "C" rotor can be used together, but not a "A" rotor and a "D" or "E" rotor.
Whether or not this is true I do not know. Its just what I read.

Luke, use the gear side (that's where they are located on my rotors).

Oh, he is asking about two different letters on the same rotor. I am on my computer in my garage (wireless network in the house) and I am putting together a motor right now. If I had better understood his question a few minutes sooner I could have looked at mine to add some better input. Sorry

The letter to match is always on the gear side..And its the letter thats on position "3"of the rotor (99% of the time), the other 1% its marked on position "6",(probably when they were training someone to stamp rotors), each rotor is stamped 1-3-5 on the gear side, 2-4-6 on the non gear side.
The rotor he has is a "C", and the E as ted said, is "YO"...Max

There is no direct English translation for these katakana characters.
Only Kanji (Chinese characters) might have English translation for single characters.
Short Japanese language lesson...
The Japan language is based on a "phonetic" alphabet.
The "hiragana" character set is "native", and the "katakana" character set is typically used for foreign word (i.e. English, French, etc.).
The hiragana and katakana set describe the SAME phonetic pronounciation, but the actual characters are difference - some are very similar.
Strings of these characters are used to make complete "words".
