'93 EJ18 to '97 EJ22 swap

[annointed]

Yes, that's right, I'm looking to add a whopping 20 hp and 25 ft-lbs to my '93 Impreza L wagon, along with upgrading to the bulletproof, non-interference EJ22. Actually, the EJ18 sounds like it has some bottom end damage and smells REALLY bad like rotton eggs when you start it up, along with making a lot of loud noises (but it still runs and moves under its own power).

Anyway, I'm looking for an EJ18 to replace it, but since I have an EJ22 laying around from a '97 Impreza, I was wondering how easy it is to just swap that into the '93?

Specifically, will it be plug and play? Or will I have to swap any of the EJ18's accessories to make it work? Are there any components that simply won't swap?

The EJ18 ECU will probably have to run the whole set up, since I highly doubt that the '97 EJ22 ecu will plug up to the '93 harness.

Thanks for any heads ups and insights!

yeah will prolly work ... what years are the engines?
i have a 1.8 laying around .. but ... kinda far away ..

What years are the engines? Lol, Jaxx, did you even read my post?

Sorry, Jaxx, had to do it. You've been there through my first and now second swaps over the past 2 years. I wish you were closer too, I might just scoop up your EJ18. I personally am figuring that the EJ22 will drop right in, and that I can probably swap sensors, etc that don't match the EJ18 wiring harness, but figured it can't hurt to ask here too.

hmm sorry bad day at work ...

i would just take the harness and the vacume lines off the 1.8 and put it on the 2.2
all the sensors should work

what is the compression on the 2.2??

That's exactly what I'm trying to confirm, whether every plug/connector will just mate up or not. I'd be pleasantly surprised if they do, but I'm hoping that the components that don't plug and play I can swap from the EJ18 block onto the EJ22 motor, and not skip a beat.

Hey mark

I put my old EJ22 in my buddies 93 EJ18 car. There are only two plugs on the block: crank and cam sensor that need to be connected, I dont think the 93 has a knock sensor. The COMPLETE 1.8l intake will bolt to the 2.2 so no worries. Just pull the HOLE intake off and swap them. My 98 EJ22 didnt have any EGR ports on the exhaust but thats not really a problem, I am thinking your 97 wont either, it will just throw an EGR code. Most 2.2 use the same injectors as 1.8 The 1.8 ecu seems to run the 2.2 fine!!

Have fun swapping

Sorry to disappoint you, but the EJ22 became an interference motor in '97. You'll want a '96 for a non-interference motor.

You may run into a few wiring issues.

My buddy dropped a 2.2L motor (not sure what year) into his 1996 Impreza 1.8L, and everything was pretty much bolt up (no wiring).

Well that's good to know. So that means that the EJ22 in my '96 Legacy is still a free spinning motor, right? I'm pretty sure that its never had a timing belt change in 158k miles!

Now, why did the change it to an interference motor? Does it have anything to do w/ Phase I vs. Phase II motors?

The '96 Legacy should be interference-free also.

The change was probably required to go from 9.5:1 to 9.7:1 CR, which bumped peak hp from 135 hp to 137 hp.

I just got a 95 2.2L NA motor to swap out the 93ish (maybe newer, I don't remember) motor in my 93 Impreza.

The plugs are different so I just swaped the entire intake mani, crank and cam sensors. The 2.2 has a knock sensor on the back whereas the 1.8 seems to have it in the power steering pump mounting bracket. I also put the red top 2.2L injectors on there.

I'll drop it in as soon as I can get a truck for a few hours and rent a cherry picker. Right now the engine is just sitting next to the car.

Oh and BTW, I thought the red top injectors were 280cc, why does the 95 2.2 have red injectors? The 1.8 injectors were gray and are for sale along with the fuel rails.

I have seen both red and gray tops in 2.2l Most 2.2l had gray tops, my 98 had gray tops but my sisters 2.2l legacy has red top. I think the cc are close enough either will work fine.

so confusing feel like im in class

Ah, good memories. I sold the green '93 wagon with the swapped EJ22 years ago. It's kind of funny, I did the EJ22 swap in one weekend while the parents were on vacation and did a 240sx engine swap that same weekend! I just had to pull their cars out of the garage to make room for the projects! Man, it's nice having my own garage now.

Also, last I heard, the green '93 wagon was rolling around in Camden on chrome dubs!

Only the phase 2 2.2 engines are interference.

No sohc Subaru engine is an interference engine .period

Wrong in too many ways.......Please delete your post before someone accidently takes it as truth.

I got 94L 1.8 awd and I have a 99' 2.2 sohc engine and tranny, so the 1.8L ecu will run this 2.2 without issue?

[urabus555]

^^^
Will it run LEAN???

~very curious~

[Storm]

It'll run pretty good. If you run into issues, it'll only be at WOT. My 96 EJ18 ECU ran an EJ25D with no issues, but I added a piggyback fuel controller to dial it in a little better.

Next time I get a set of bent valves in a 99+ EJ22 or EJ25 I'll take a picture.

i just finished swapping a ej22 into a 94 impreza.
i used the intake manifold, wiring, crank and cam sensors off the ej18 and put them on the ej22
the engine turns over and has good compression but no spark.
when i turn the key off the fuel pump runs constantly and the check engine light is on but no other lights.
when the key is on the check engine light turns off.
the car ran and drove fine with the ej18 but it had blown head gaskets


what did i do wrong? someone please help

You have a bad ground or left a ground wire off somewhere.
