take one turbowagon (mine for instance) with a crappy motor

add one $450 legacy sedan smacked in the back end (103k miles!)

what does that add up to?



A whole lot of work for me to do!!!!!
here come the questions.

-Wiring: I need the engine wiring harness, (how much of the other engine bay electrical?) and everything under the dash that plugs into the ECU because I can cut the extra off later. am i missing anything or wrong about anything? fusebox?? etc

-Exhaust: Can I expect the legacy Y-pipe to fit my EA82 crossmember and body? How about the rear exhaust (on my brat)?

-Axles: Legacy is a 91 or 92 2WD auto. Will the axles fit on any other EJ (I'm thinking sell them to recoup some of the cost) Or will the legacy axles work OK on my wagon's EA trans if I do a 5 lug swap later? I know Impreza axles will...

-clearance: I understand that the EJ22 will not give me frontal clearance problems in the wagon's engine bay, correct?

-plumbing: Mating the EJ power steering lines to my EA system - any insights? I can come up with something, I'm sure... redoing the upper EJ lines to fit on an EA rack, most likely... also, I'm assuming that I will need custom lines made for the A/C?

-has anyone done an EJ swap into an EA82 vehicle yet, or just EA81s?

thanks! I owe beer to everyone who answers my questions.

if its a auto swap
then you need the ecu and the tranny control box
if its a manul engine/ecu swap
then you need the manual ecu
less wires to hack up

out side of tha you need the engine harness up to the plugs and to make it easier grab as much of the harness afte the plugs o the fireall as you can.. trust me short hareness mods suck .. alt

thanks... so I could grab all the engine bay wiring and then go to the JY and get an ECU and ECU harness from a 5 speed car? I'd be OK with that if so..

The EJ22 should fit nicer into an Ea82 body then it did on mine.. the Ea81 body is narrower, but the heads cleared the sides, and the Y pipe and mid pipe all fit in there (tight squeese, you willl need to remove the heat shields from the cat to make it fit near the radius rod plates in the ea81 bodys)

the front clearance is a lot less, in an ea81 body with the stock rad. I had to use a AC fan mounted at a funny angle, because the tbelt casing and the serpentine style pulley setup (dual belt, AC/alt/PS) put the engine only an inch or so from the fan... (the thin AC fan!)

the radiator hoses are a pain just so you know ahead of time... be prepared to customise something in there!

the wiring..
I have the whole front harness and ECU that I removed from the wrecked legacy, you need the parts between the ECU<--->Engine and if its wiring from an AT, then ECU<-->TCU<--->Engine with the AT/MT selector wires jumped if you convert to an MT.

fuel pump- use ea82T

Axles- All the early EJ trannys are 25 spline, so you need to use ea82T MT (25spline) axles. make sure your rear diff matches your front! (4.11? 3.9?)
driveline- lengthen it by 55mm or so from ea82 length.. there is a shop in the yakima area that Jerry knows about that has good prices...

the EJ temp guage sensor are compatible with the ea series dash... just connect the one yellow wire for temp (you will see it, its on the back of the coolant plentum under the right rear leg of the intake) there are 2 sensors, one for ECU, and one for the guage)

the EJ22 has an idiot light oil sender, so you can use that, or you will have to plumb an EA style sender into the EJ's sender's hole- (sender is under the alternator on top of the motor)

good luck with the conversion! :D

"extra" bolts left over are a sign of a discriminating mechanic who knows which parts can be safely removed to result in a lighter and more efficient car.
now if you'll excuse me, i have to go figure out where all the rattling noises in my brat are coming from.

That sounds like a lot more work than I'll have to do for my EJ22 conv. for my 86' GL wagon, give a shout out to mudrat79, he's in this forum, he makes an adapter kit that adapts engine to tranny, so you can keep your stock tranny and starter, no trimming of drive line, no axle swaps, still a good amount of wiring, and you will still have to swap your P/S if you want it, i'm going without P/S. Holla at him and he'll tell ya all about it.

thanks, but i know about it... i'm going to make my own adapter.

my wagon has an RX D/R trans and I'm keeping it!
I'm also putting in a remanufactured XT steering rack. :brow:

You do realize the EJ22 won't bolt to your EA82 tranny, right?


You'll need an adapter, or a newer gen. manual tranny


Just read th elast few posts...somebody already mentioned this....oh well...:rolleyes:

i'm going to use a dead transmission that Brian/Monstaru has in his garage, and the EJ22 once i get it, to make the template, to make the adapter. I have access to a drill press and jigsaw and dremel tool and all that good stuff. Should be super easy since the bottom studs/holes line up the same on EA and EJ transmissions. Drill the bottom two holes, mark the top/outer EJ engine and bottom/inner EA trans, and cut out a template!

I just got ahold of an XT6 flywheel thanks to Brian, as well as an XT6 clutch, so I will use the XT6 flywheel (adjust the bolt holes to fit the EJ crank), my wagon's current kevlar clutch disc, and I'm going to have a shop eyeball the XT6 pressure plate before I go ahead and use it. For all I know it could be a regular EA82T clutch if someone didn't want to pay extra (?) for an XT6 clutch package. It looks like it was used aggressively from the heat coloration, so it may be a case of a non-XT6 clutch that was slipping because the XT6 engine was too strong for it.

WHEN WE LAST LEFT OUR HERO...
he was stymied by the loss of the perfect engine donor candidate and left with nothing but unanswered questions...

now I have a 1990 legacy with a few more miles but for ZERO DOLLARS BABY (just have to change a fender and a bumper on its replacement, for the old owner). I've also found out that the XT6 clutch was toast so I took it back to the junkyard, slapped the clerk around and got my money back. I also have the XT6 seats installed in my wagon (looks so good it hurts not to be driving it!) and with the legacy I have all parts needed to complete the 5 lug swap. Including new front axles. Next step is extracting the EJ22 and wiring and gas pedal/cable and 5 lug parts and disposing of the corpse. Thanks to the low low cost of the donor, I will probably buy some new KYB GR2s for the front (to match the ones in the back) as soon as I have the other costs all figured out. I will probably order a lift with my tax refund. I plan to roll into WCSS 7 (or 8 or whatever) with all that and tinted windows :cool:....

STAY TUNED FOR THE NEXT CHAPTER....

latest update..

I just grabbed one of these

Posted Image

off of a nissan truck at the junkyard. it wraps around the front of an EA82 car perfectly. I'm going to chop the bottom tube off to save weight (i'm not hardcore enough to need two tubes :P )
and for turn signals i have something like this in mind:

Posted Image

this is of course after i finish the EJ22 swap and can actually drive the car.
i will be receiving my lift kit next week :banana: and then i will reassemble the front suspension.
i figured: the car has no engine in it. i have to tear apart the front end to do the 5-lug conversion, and to lift it, so i haven't put the 5-lug legacy parts on yet.

right now i'm going to go finish cutting the adapter and redoing the foam on the heater box-thing and then take them out to the secret subaru lab so i can mark the adapter for the top 4 holes that have to be tapped. i also will change the two axle boots on one of my legacy axles as well as swap the wagon's old EA82 struts/RX springs into my Brat, and thus free up the EA82 strut tower tops for the Legacy struts, for the lift, which I get next week. I also want to start tune-upping the front end of the Legacy engine as well as changing the rear main seal.
then as soon as I get the flywheel machined, I will be good to stick the engine in and start headaching over the wiring.

Huzzah, i'm back in the EJ-22 swap camp again, i got a new car, so i don't need the legacy, and if i sold it i couldn't get enough for the tranny swap for the OBS and the engine swap for the 88. So, hopefully the 88 will be running with EJ-22 power by the end of the summer, just waiting on a few parts and she will be good to go. Anyone in SE Michigan that wants to join a wrenching party, beer and pizza, root beer if ya be a miner, or a minor.
