June 20, 200916 yr right, so im looking at an engine rebuild kit for sale, and i noticed that is says EA81 for years 1983-1984 and Subaru Brat and 1800 - EA81 1.8L Turbo engine. P/N 592-100. also, does the turbo part make any difference? im assuming it doesnt the question is then, is there a difference in EA81's from 83-84 compared to the ones after that? cheers guys!
June 20, 200916 yr Different head gaskets, different intake gaskets, possibly different valve cover gaskets as well. Those were the only two years of the EA81T IIRC. After that, they just carried on the Brat and Hatch with the EA81, while the sedan and wagon could be had with the EA82T or plain EA82.
June 20, 200916 yr The earlier EA81 engines had solid lifters, whereas 85' + had hydraulic lifters. I don't know much about the EA81T, but i sure as schat wouldn't buy a rebuild kit for one thinking it would interchange with an N/A motor.
June 20, 200916 yr Author so the head gaskets are different from the 83-84 ea81's compared to the later ones or the turbo ones? with the turbo, i dont see why there should be any difference? ive often seen EA81/T on head gasket sets, the one i brought once says it, and it is on there now, just wondering if anyone has had any differneces with the turbo ones? the valve and intake ones i aint worried bout, i got aftermarket heads and inlets ive got a block with 9.7:1 compression pistons or similar that i brought, SUB4 dualport heads, a choice of 2 hot cams, and just need the bits inbewtween to build it up, will investigate things further, just putting a bit of research in before i start buying stuff!
June 20, 200916 yr The head gaskets are not different between the earlier ones and the later ones. I ordered 86 head gaskets for my 83 engine and they fit fine and have not leaked a drop
June 20, 200916 yr There is no differences in the basic engine gaskets - heads, intake and exhaust, valve covers, oil pan etc will all be the same. The turbo kit might include some extra gaskets that the NA kit does not. The rings may be different - that I don't know. The pistons are lower compression so it's possible they used different rings on them. GD
June 21, 200916 yr Author right, thats alright, i shall give it a go when i get the cash together, and then i can start building me an engine! cheers guys!
June 21, 200916 yr After looking at a couple sites for rebuild kits, it appears that 80-82 non-turbo, 83-89 non-turbo, and 83-84 turbo all have different part numbers.
June 21, 200916 yr Author well this is it, thats what confuses me, surely if the EA81 were to change, it would make it like an EA81/a EA81/b or somin surely? its really quite annoying! i just basically want a full rebuild kit for mine (shells, rings, gaskets), which is a later N/A engine, (1993), the only one i could find was a 83-84 or that time scale, which were a full kit, i dont want to buy one from here, one from there, and end up getting like over sized wrong or somin stupid, and then the shipping delay which would probably be weeks difference for me! also, can anyone direct me to a good rebuild kit of their choice?
June 21, 200916 yr We didn't even get the EA81 past 1989 in the US, so any US supplier is unlikey to even have a listing for a 1993 EA81. You might have to check with a dealer in the UK or Japan to verify if that's the same as the 80's ones.
September 12, 20205 yr I have a 1983 subaru gl with the 1.8l engine I want to trade for a subaru brat or a wagon around the same year
