Default ea82t? possiblities?

so I just saw a ea82t for sale, cheap actually. does anyone know anything about thease engines. my thoughts (please correct me if I am wrong) are that it is probably a closed deck engine as I think that subaru was in the business of making most of there engines closed decks in the late 80's early 90's. I'm sure that the heads probably dont flow all that great as it was I think like a 120hp engine. could a guy maybe mate ej18e heads to this block along with the intake manafoild and assorted goodies and have something that works? or could you even get a 2.2 or 1.8 manifold to work on it? any info would be helpfull as I am a knowledge whore.

Lots of possibilities with an EA82T. However, among those possibilities are not any EJ series parts conversions (with the exception of a few small things, like the turbos from both the turbo legacies and WRXs// But even those don't just bolt right on.. it requires some work)

the ea82t has the best flowing heads of any 2 valve per cyl engine ever made. its just not tuned for power, the turbo is for efficancy.

with just bolt on parts, you can make around 250hp at the crank, i think thats what will had isnt it calebz?

the ea82t im going to have built up shouldtip the scales around 300-350 hp and 400tq.

granted its going to take a lot of money and time to get it to that point. im not leaving any thing untouched in that engine.

EA-82T has the WORST heads I've seen on a motor. Now I haven't gone looking for horrible motors from the 50's where I might find worse ones... but still for 1985 these things are horrid.

That said the shortblock is nearly indestructible. Even low compression issues will run fine and make power. Just takes more rpm to make boost and makes jack for power off boost.

Fairly tough little buggers too. Don't overheat them or they blow up in a hurry. However by some freak of nature occurance the first motor my old wagon had went over a week of driving in 90+ degree temps... without any coolant or blowing up. The second motor already had lost a headgasket, and driving through the desert it ate enough coolant to start to overheat. By the time I got to a safe spot the mobil 1 sythetic was starting to burn it was so hot. Warped the drivers side head so bad it would spit coolant out at idle along a 3" length of the head.

i didnt say that the ehads were the best design, just that they flow well as compared to any other stock head of simular set up. i think that makes sence.

Makes sense, but its not true Compared to other similarly sized turbo motors of the time, they still sorta suck

i think the sorce for my standing came from the book "impreza". basically, the history of subaru with aloth of high quality pictures.


and i think the other turbo engines of simular "size" had about 4 valves per cylender. or at least three valves, the ea82 is the only one ive seen with 2 per cyl.


then again, you might be 100% correct and i might be an idiot, i have been posting mostly after work when im spaced out and when i first wake up and can barely see the monitor clearly.

The flow is horrid. One port on each head has to take a large bend around the lifter.

Don't get me started on the single exhaust port per head issue. Its one of the reasons that you can cook off the passenger side head in a hurry. Long exhaust paths are a good way to transfer heat into the head. Then add in the outside is virtualy wrapped with exhaust pipe and the turbo dumps its hot oil into the head... ouch.

Seriously these heads make a Stock 80's Ford 302 head look like a work of art.

I had an '86 Coupe a while ago. They look beautiful, and with the D/R AWD setup (locking centre diff FTMFW) it was good at the beach. However, the engines are ****.
