...all the EAxx numbers? You know, EA81, EA82 etc etc. What the heck do they all mean? I've searched for a thread but find nothing. I'm ignorant about alot..so thought I'd maybe could take one thing off the list!!!

those are engine designation numbers for the old-gen cars (pre 90, or loyale).

 

in most cases here, a certain body style is also refered to by the type of engine it contained.

 

EA81 - OHV, uses timing chain (I think), I don't know much about them since I don't have one, typically early 80s and were carbed

 

EA82 - OHC, uses two timing belts, non-interference engine, used mostly in later 80's cars, and loyales, mostly FI, some where carbed

 

hope this answers a few questions you had.

 

edit: here's a good post that outlines some of the differences. http://www.ultimatesubaru.org/forum/showpost.php?p=153266&postcount=3
