85
differences are
Larger a/f meter, throttle body, and intake ports on the engine. smaller injectors. running a different computer, and wiring.
Also it has 2mm apex seals. where as the 84-85 has 3mm seals.
84-85 13b produced slightly less power but it is a longer lasting engine, and more reliable.

Buckaroo....
Haynes puts out a fairly decent manual, and it has a section covering 13B stuff. Otherwise get a "factory" shop manual available either from your local ignorant Mazda dealer, or Mazdatrix....
As I understand it, the wiring harness is much different on the 2nd gens from the 1st gens....It sure is on our '87 2nd gen parts car....

Thank you for the info. Here is the situation... I bought an 85 SE, got a new engine, and turbo as a package deal. I need to know how to tell the difference between an 85 and 86 engine. Would I be better off buying the Hayes 86 manual because I have the 85 manual, but it doesn't cover enough infor on the 13b. thanks again. Yadda, yadda, yadda...
