NoahDL88 Posted March 17, 2005 Share Posted March 17, 2005 EA-81 are cam in block EA-82 are over head cam, and most have fuel injection Quote Link to comment Share on other sites More sharing options...
Bro Posted March 17, 2005 Share Posted March 17, 2005 EA81's are almost bullet proof and the EA82 (though more powerful) are known here as, head crackers :-p Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted March 17, 2005 Share Posted March 17, 2005 Generally Speaking: EA81 - gear driven cam - more reliable, more low-end torque, not as high reving EA82 - T-belt driven cams - more reving potential, more high-end speed torque, can do 5,000rpms all day Modifications can make exceptions to all above statements - both engines are pretty tuneable, but if your want to milk every hp per cc displacement, the EA82 is your best bet. EA82 turbos crack heads, other don't gen 1 cars are through 1979 for all cars except Brats (through '81?) - older, more traditional design I can't remember exactly what makes a gen 2; but I do know the engine designations for the difft cars EA71 - 197?-1987 - 1.6L OHV EA81 - 1980-1984 - 1.8L OHV (used thru 1987 on all Brats and Hatchbacks) EA82 - 1985-1994 - 1.8L OHC Quote Link to comment Share on other sites More sharing options...
Bro Posted March 17, 2005 Share Posted March 17, 2005 EA82 turbos crack heads, other don't Here is Aus, I know of 3 Suby yards that sell EA82 (non turbo) heads all day, every day for $150 a piece. So to say that only the Turbos crack heads, I have 3 yards here to say different. Quote Link to comment Share on other sites More sharing options...
Ross Posted March 17, 2005 Share Posted March 17, 2005 ea81 and ea82s crack heads, but they are usually blind cracks that cause no harm (just between the valves), so all those people buying heads from that wrecker may be wasting their money! The ea82t does seem to have worse issues when they are overheated, but you shouldn't be overheating it anyway! Quote Link to comment Share on other sites More sharing options...
Subaru_dude Posted March 18, 2005 Author Share Posted March 18, 2005 so would my '87 carbed GL wag have an ea82? Quote Link to comment Share on other sites More sharing options...
Ross Posted March 18, 2005 Share Posted March 18, 2005 yes. Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted March 19, 2005 Share Posted March 19, 2005 Here is Aus, I know of 3 Suby yards that sell EA82 (non turbo) heads all day, every day for $150 a piece. So to say that only the Turbos crack heads, I have 3 yards here to say different. US vs. Int'l = BIG DIFFERENCE besides, I have at least half a dozen shops and JY's that know subarus - none sells N/A heads on a frequent basis because they don't crack (or at least in a way that affects performance) - I have enough hard miles on mine to know if it would have cracked yet - warp if overheated, yes - but cracking is not a problem here when it comes to performance none of the cars I've seen in the JY with over 170k miles on them had unuseable heads either - their piston rings were just worn out, they had blown a head gasket, or (most common reason) their owner's got tired of them - I started one up with over 250k miles on the engine - know it was orig. engine because I had a connection to the last owner - burnt some oil at startup, but ran fine otherwise Ross also has a point - all of 'em crack a bit - most of the cracks are negledgeable, turbos can be the exception Quote Link to comment Share on other sites More sharing options...
Erik R Posted March 21, 2005 Share Posted March 21, 2005 Always have used heads pressure tested before using........................ Many have porosity leaks into the exhaust port. The crack between the valves doesn't mean much unless it's severe. JMHO Quote Link to comment Share on other sites More sharing options...
Phizinza Posted March 21, 2005 Share Posted March 21, 2005 BTW, here is Australia we can Brumbies (Brats) that go up until 1994. Still think they have the EA81. I have a 89 Brumby with an EA81 and toursion bar rear suspention, it also has qual headlights. (GL I think that means) Quote Link to comment Share on other sites More sharing options...
FlyB0y Posted March 21, 2005 Share Posted March 21, 2005 the more I learn about my EA-81 the more I am happy that I have one :cool: Quote Link to comment Share on other sites More sharing options...

I have a 89 Brumby with an EA81 and toursion bar rear suspention, it also has qual headlights. (GL I think that means) The dates I gave are for US imports - I know they vary country-to-country. I genuinely wish (as many others do) that the brat had continued as long here as it did there - it was a nice vehicle. I kinda wish subaru had updated it to the EA82 series body, but that never happened. the more I learn about my EA-81 the more I am happy that I have one :cool: The EA82 is not a bad engine nor are most any others that subaru has made - though I do like the valve timing mechanism on the EA81 for its reliability and serviceability. It is a very good car! Quote Link to comment Share on other sites More sharing options...
