esteveW Posted December 30, 2009 Share Posted December 30, 2009 (edited) I can't seem to find a model year time line for the fuel systems. As I prowl the junk yards I seem to find SPFI on all and have yet to come across a MPFI, until I get to the EJ22 engines (which is true port injected). My Haynes manual (1970-1984) shows a 2 injector (right and left bank) in some instances. Does the ea81 and ea82 have anything to do with this time line?? I looked at a '86 and '89 which both had MPFI yesterday and wonder what year they went to MPFI (two injectors) and was the ej22 the first to have four injectors?? Earlier in the week, I looked at a 85 and it was carb'd. It would also be helpful to see a time line for hydraulic lifter (lash adj.) and solid lifter along with interference and non-interference models. Or for that matter, when did they go from cam in block to single and cam in head?? My head is spinning, especially when I get to the junk yard and can't remember what I'm suppose to know.

MilesFox Posted December 30, 2009 Share Posted December 30, 2009 ea81 mpfi (Turbo) for 83 and 84 only mpfi with mechanical disty in 85-87.5 xt, and then for all ea82 turbo and all 4 cyl xt thereafter spfi for 86 in gl10, some carb or spfi for 87 ea82, then 88 and up all spfi if not turbo. spfi never came in the xt Link to comment Share on other sites More sharing options...

Thanks, Steve most US sold EA81's were carb'ed except turbos which have mpfi. ALL EA81 engines have the camshaft in the block, gear driven by the crankshaft, and had solid lifters till mid 80's. look for gold stickers on the valve covers that say "do not adjust" - those are hydro lifter engines. also, hydro lifter blocks don't have the two little bolts on the bottom of the head, just little "tabs" to cover the holes in the block. solid & hydro lifter heads are interchangeable (use the rocker assembly that matches your lifters) and the hydro lifter heads have 2mm bigger intake valves. EA81 equipped cars were sold from 80-84 except brats and hatchbacks which were discontinued for the US a few years later. EA82's (85-94?) all came carb'ed or mpfi turbo till 86 when spfi became available. spfi was refined in 87 so the earliest models are not good donors for those parts. all EA82 motors have a single ohc in each head and a timing belt for each. EA82 engines suck and came in hideous cars but they had lots of goodies to retrofit onto EA81 engines and cars. EJ series engines are a whole different world from EA81's/82's. EJ engines all have 16 valves as opposed to 8 in EA engines and EJ's have a single timing belt that is much more well designed than an EA82. in the US, every EJ you find will be mpfi, carb'ed models weren't sold here and i'm not aware of spfi on an EJ. all EJ's are sohc except wrx turbos and early 2.5's. look at the front of a few motors and you should easily see by the shape of the t-belt cover if the heads are sohc or dohc. every EJ22 is hydro lifter until 96 when solid lifters showed up. factory specs show solid lifters started in 97 but i've seen 96's with solid lifters, 2 of them. ...i might get flamed cuz i'm no expert but i tried.

Loyale 2.7 Turbo Posted December 30, 2009 Share Posted December 30, 2009 (edited) ea81 mpfi (Turbo) for 83 and 84 only mpfi with mechanical disty in 85-87.5 xt, and then for all ea82 turbo and all 4 cyl xt thereafter spfi for 86 in gl10, some carb or spfi for 87 ea82, then 88 and up all spfi if not turbo. spfi never came in the xt This is True... Specially for the USA Market, 'cos in Latin America we had Carbed Subies from EA series 'till 94 and the Early EJ Series came Carbed too from 89 'till that 94 Year. Kind Regards.

Gloyale Posted December 30, 2009 Share Posted December 30, 2009 Pre-83 = Carbed, everything 83-84 = EA81 engine. MPFI on Turbo Models. This is perhaps the 2 injector you spoke of? Everything else Carbed 85 = EA82 engine. 4 injector MPFI on all XT and GL-10's, Turbo MPFI on GL-10s and RX. All EA81s carbed from here out, last mention. 86 = EA82 enigne. MPFI on all XT. SPFI on 2wd. Carbed on 4WDs. Turbo MPFI on GL-10 Turbo and RX 87 = EA82 engine. MPFI on all XT. SPFI on 2wd and California. Carbed on 4wd Federal. Turbo MPFI on GL-10 Turbo and RX 88-89 = MPFI all XT. SPFI all non-turbo DL/GL. Turbo MPFI all GL Turbo, GL-10 and RX 90+ MPFI all XT and All turbo. SPFI everything else.

GeneralDisorder Posted December 30, 2009 Share Posted December 30, 2009 EA81T's were 4 injector MPFI - they just have the injectors in the heads instead of the manifold. Also - the '85 MPFI was on 2WD's only - '86 they switched to SPFI as noted. The rest were carbed or turbo. GD Link to comment Share on other sites More sharing options...
esteveW Posted December 30, 2009 Author Share Posted December 30, 2009 I'm beginning to understand and really appreciate all the input. I just printed out the info submitted so far and made a quick trip to my friendly junk yard, armed with this info and found what I was looking for. A 1987 (mgf date 01/87) wagon with 5 spd DR 187k miles and a carborated 1.8 ea82 engine. (correct me it I'm wrong) Single Overhead Cam. Car had front end damage but engine survived and turns over with good compression. I'm going to try and purchase the whole car and take the whole drive train and put it in my EA71 Brat. I'll save my EJ22 engine for another, more deserving project. And if the 1.8 doesn't work out, at least I will already have the transmission/drive train and PS in the Brat. I should hear from the yard owner tomorrow. I have really got a lot of good use out of this Thread and if this info wasn't already consoludated on this site, it sure is now.

GeneralDisorder Posted December 31, 2009 Share Posted December 31, 2009 (edited) An EA82 won't fit between the frame rails of a first generation Brat. You will have to notch the rails inward about 2" on each side to clear the cam-tower/valve cover and weld bracing into the notches to maintain the integrity of the frame. EA81 or EJ22 is a much better fit - both will fit without modification of the rails. The EA82 is just very wide due to the cam tower's where the EA81 has no OHC's and the EJ22's has them integrated into the head casting. EA82's are also the worst engine Subaru ever made. They are notorious for broken timing belts, blown head gaskets, and cracked heads. Not worth the trouble at all. EJ22 is the only way to go and you can pickup whole donor cars for under $500 just about all the time.

esteveW Posted December 31, 2009 Author Share Posted December 31, 2009 Thanks for the "heads-Up" on the EA82. I was really looking for a carb'ed engine when I came across this one. Also the 5 spd DR tranny is still important find to me. The carb'd engine would make for a quick change over to a engine that will work directly with the 5 spd tanny. The car is still driveable and plated (title hasn't been totaled yet) so I may just drive it for a while and see how everything else checks out.. Never owned a Soobie before my Brat and it isn't titled right now. Looks like fun to play with. Well engineered engines, compared to the Vanagon WaterBoxers I have around here.

GeneralDisorder Posted December 31, 2009 Share Posted December 31, 2009 The EA82's are frustrating engines. They were designed only well enough to do the job they do in stock form. They don't take to modifications well at all and the added 10 HP you get with the EA82 vs. the EA81 is easily made up with a better cam and some added carburetion. The EJ22 can be carbed as well. There is a place for the distributor on the back of the passenger side head - people use Ford Escort distributors and just build a custom manifold to mount a Weber.

Yo'J Posted January 1, 2010 Share Posted January 1, 2010 I believe the hydro lifter ea81 motors are only 85 and after in the brat and hatchback. Brat production ended in 87 and hatchback in 89 (?)for the us models. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 1, 2010 Share Posted January 1, 2010 Hydro lifters were on all automatic transmission EA81's starting in '83. Manual's got them in '85 GD Link to comment Share on other sites More sharing options...

Manual's got them in '85 GD Yup my 84 Sedan nwith 3AT 4wd is a Hydro Motor. My 84 Wagon 4mt 4wd is a solid lifter (and due for valve adjusment:rolleyes:) Link to comment Share on other sites More sharing options...
