if it has a hitachi it is likely a 74-78, i don't see why anyone would bother trying to make it work on a late series 13B.
74-75 had the old slanted MAZDA logo(all capitals), the 76-78 engines have the traditional logo used up until current.

how old is my B-13?
If, by logo you mean the word MAZDA on the engine block, then it must be a 76-78 engine cuz the word is in upright (not slanted) letters- is this correct?

Hi guys, plz help i.d where my 13b is originally from.
it has pollution gear on it. my car is an rx7 series 2 and originally came with a 12a. id like to know the year the 13b is from so i can look up ignition timing references i suspect the breakerless ignition with 2 vacuum advance units on it are from a 12A? are the dizzis interchangable between 13b and 12a? |
