I have a '95 Legacy wagon with automatic that I just bought for $250. The engine needs a head gasket and the transmission needs a duty C cycle. On Sunday I'm picking up a '93 EJ22 dual exhaust port engine with auto trans combo (still together). Both engines are phase one and dual port, but the '93 is OBDI while my car is OBDII. What kind of issues might I run into? I will have the ECU from the '93 if that helps, but I also assume I can just swap out the intake from my '95 and put it onto the '93 along with any other sensors that may have different wiring.

 

Any known issues I might run into and how can I over come them? The '93 engine and trans are ready to run and the cost is $300. Thanks in advance.

just bolt the 95 intake manifold onto the 93 and you're essentially done. both have EGR so you made this really easy on yourself, woot woot!

the 93 ej22 will bolt in and run fine if you swap the intake and therefore the wiring harness. the one exception is that the 95 auto has an EGR valve and the 93 does not. you will have to ''drill and tap'' the head to make it work. if you do not ''make the repair'' for the egr you will have a CEL all the time. not an issue for a 95 since they are not required to meet the OBD2 specs, but it will have a CEL on the dash.

 

the trans will bolt in and work, BUT the final drive ratio may be different so it may not match your existing rear diff. but if your current trans still works you don't really need to swap, do you?

 

if you go to legacycentral.org and look for the sticky that covers diff ratios you will learn what you need. i think they may be the same but i'm not sure. 90 -91 are different from 92 -94 but the same as 95 - 99, non turbo, i think. double check.

oh, hey JCE, i thought the pre-95's had EGR but it's been awhile since i've seen one.

honestly , i don't know. but i have drilled into my brain that only 95 - 99 auto ej22 had EGR i assumed the 90 - 94 did not. id they did , then they would be a good candidate for an je25 swap as long as you had an ej22 intake / harness from 95 - 99.

 

i do know that the ej18s all had egr, so i guess the early ej22 could have had them as well. but again, double check.

I have a '93 EJ22E from a Legacy auto that doesn't have EGR FWIW

Well, I did buy the '93 EJ22 and auto trans and it came with the ECU. I plan to just swap the intake manifold, but not sure what to doe about the EGR. Since I still plan on doing head gaskets I could swap the heads as well rather than drilling my own EGR port in the head. Just out of curiosity, could I use the '93 ECU in my '95 car so I wouldn't have to deal with the EGR at all? Perhaps I will experiment.

 

Now, I didn't really need the trans but I was crunched for time and I thought I could just separate it from the engine and sell it later if I wanted to. A couple of things to consider are the speedo, sport mode, and gear ratios. I believe the speedo in my '95 is electronic (sensor) versus the mechanical (cable) of the '93 and I'm not sure if that can be over come. Sport mode I think can be accomplished by grounding out a terminal on the ECU or TCU. The final question, how do I identify the gear ratio on both transmissions? Any thoughts or experience on the other items is appreciated as well.

the speedo is a non-issue, just un-thread the speed sensor from one and swap it to the other, done.

 

tyhe gear ratio on the other hand may make the difference. the 95 auto trans has a final drive ratio of 4.11. you can look over on the legacy central forum for the auto trans ratio in the 92 - 94. i thin it is 3.9 but you will have to double check.

yeah i'd just use the 93 short block and keep it simple - bolt the 95 heads and intake manifold to the 93 block. then you retain EGR.

 

you *could* plumb the EGR down to the exhaust and custom fab some lines that way since the "engine" side of the EGR only need to see the exhaust ports. or drill and tap the heads to match. that's a bit more custom.

 

if you live in a state like I do where it doesn't matter, then you can install the 93 long block and not hook up the EGR. you'll get a check engine light that's impossible to get rid of (a ton of threads/posts about that), but doesn't affect how the car drives. we don't have to worry about CEL's in WV so i don't worry about it.

 

i have a non EGR engine and a non EGR ECU in a vehicle that was originally an EGR vehicle - so just swapping ECU's does not necessarily get rid of the EGR codes.

A 95 legacy auto had a EGR the manual version did not.

putting the 95 heads and intake on the 93 block would make it work. but it would be less work and money to just do the head gaskets on the 95 engine. unless it has other problems.

 

from the less work side i would just install the 93 with the 95 intake and plug the EGR port. you'll end up with a CEL but does that matter in Waterford, WI ? the car should run fine even with the CEL. then you can sell or repair the 95 as you like.

I think I'll head to a junk yard and look for a '95/OBDII EJ22 complete manifold assembly with EGR and the one matching head and basically convert my '93 engine to a '95. That way I will have two correct engines, one waiting and ready to go.

it's an EJ22, you won't need a back up!

 

a machine shop can mill and test the 95 heads for you, they are likely good. any old head should probably be inspected, possibly tested, and possibly gone over with milling, valve job, pressure test depending how many miles you expect. the block is the more questionable part as there's no way to inspect bearings easily.

what he said. you will not need a back up.

 

but you could fix it and then go looking for an outback with a bad engine.

It appears I got lucky on this one. The guy that sold me the engine and trans on Craigslist said the EJ22 and 4EAT came out of a 1993 Legacy. So, according to the legacycentral.org (specific link below), that would have made it a 3.90 gear ratio trans and incompatible with my 1995 Legacy wagon which has a 4.11 gear ratio. To be certain, I checked the trans numbers and here's what I found.

 

In my '95 Legacy: TZ102ZAAAA-C7

Trans from CL: TZ102ZA1AA-JS

 

Again, according to the legacycentral, my engine and trans are actually out of a 1991 and therefore should be the 4.11 ratio and the same as my '95.

 

Wanting to be more certain still, I checked my rear diff for a gear ratio and found nothing other than a "T 2" sticker, and the following castings:

 

314

4Z

KN51

 

Can any one confirm my findings?

Oh, and by the way, does a 4.11 LSD exist? How interchangeable are Subaru rear diffs? What years/models are interchangable (I suspect there are differences in axle length and spline count)?

yes.

 

in the early 00s VLSD were available in the outbacks, a 4.11 would be in a 5 speed. by 03 vlsd was standard on outbacks and available in GTs, (if not standard.) and as mentioned above the rear diff have not really changed in 30 years. so the 03 will fit in your 95. (although i have read that the flange size changed so you may have to swap yours in from your old diff, i'm not sure.)

 

if you search www.car-part.com for legacy rear diffs - 2003 it will return several choices, stick to ''locking'' and your ratio, 4.11 which is an outback / GT manual trans.
