Default My 2.2 n/a-turbo. all stock parts, 213awhp.

figured id share my setup i built for my winter beater, i built it out of spare parts i had laying around. my total cost to build this car was <$100 including the shell.
its a 93 impreza wagon 5mt.

Motor:
2.2 n/a block w 150k on it
2.5 sohc heads
^^ this combo produces ~8:1 comp ratio, SAFE for boost!
2.5 sohc intake mani
92 legacy turbo throttle body and tps. (No iac due to the 2.5sohc TB being wrong for the ecu and the leg turbo TB not having one on it. fast idle is acheived with a emmisions VSV and a toggle switch.)

wrx manifolds/crossover/uppipe w hollow cat
VF39
custom inlet tube made from exh pipe and DSM intercooler hose
wrx top mount, with custom y pipe made from the stock plastic one/DSM hose
440cc wrx injectors
92 legacy SS ecu pinned into factory 1.8 harness (simple and works awesome)
apexi afc to scale for injectors
outback 2.5 clutch
3" dp, to 3" home made catback
techedge wideband.
Notes:
car is currently running 8psi of boost. i have no doubts this setup would handle 10-15psi no problem, but unfortunatly the turbo legacy Hitachi maf sensor is maxed out at 8psi. the outback clutch slips sometimes in 3rd gear, i have a better one, just havent installed it.
the iac situation is mickey mouse. i had a phase2 2.2 TB on it originally, but the ecu didnt like that tps, and the Tleg tps wouldnt fit the newer TB. if the temp is above 40-50deg, it starts and idles no problem. below that, the fast idle switch is needed. not a big deal, just annoying.
This build is the result of me putting my STi swapped 94 legacy away for thge winter and not wanting to drive a n/a car, or a nice car that id care if it got smashed up.
Question reliability? I have beat the absolute crap out of this thing, drifting in the snow, sliding around a lake in 3rd on rev limit for 4-5 hours, and taken plenty of decent trips. it runs perfect.
Want proof? Here you go, this was on a land&sea Dynomite at Kinetic motorworks in NH (stock sti puts down 225awhp on this dyno)

dyno vid
heres a pic of the motor


there is alot of mickey moused hackery on this thing, mostly because i didnt really care. it was an experiment, and i wanted to have next to nothing in the project. bottom line is, it works, makes power, and has proven reliable. Winning in my book
enjoy

thanks! the block is a completely stock 94 ej22e with 150k on it. Yeah, its pretty quick. stays right with/beats much newer cars. i ran my buddies stock '11 wrx and we were dead even up to 70mph

Going to be doing this exact build this summer, already have my heads, turbo, pipes, etc. using my stock PI ej22 shortblock. I'll be using my stock EJ22 ECU and apexi SAFC

Couple of questions:

Are you using the EJ251 cam gear or ej22e one and sensor?

I saw you tried using a PII ej22 TB but what about the stock PI TB on the 2.5 IM?

Would my stock MAF sensor max out if I ran more than 8psi of boost even with the SAFC?

Any issues with knock?

Did you use the OEM EJ22 head gaskets?

EDIT: Re-read so I'm assuming you are using a turbo/notched xmember?

ej22 cam gear, sensors are the same

I saw you tried using a PII ej22 TB but what about the stock PI TB on the 2.5 IM?

im using the 92 legacy turbo TB on the PII manifold. i had to make a block off plate for the iac port though on the manifold.

Would my stock MAF sensor max out if I ran more than 8psi of boost even with the SAFC?

No. the plastic JECS maf can read enough airflow for 18-19psi on a VF turbo.
The turbo legacy metal Hitachi maf has a much lower reading ability
i havent tried to run more boost and scale it with my afc, due to the simple fact that it works fine the way it is and i dont feel like messing with it.

Any issues with knock?

none that im aware of, i have no way to monitor it, but if it had knock issues, it would have blown up long ago after the abuse ive put this motor through.

Did you use the OEM EJ22 head gaskets?

i used ej251 head gaskets from napa.

EDIT: Re-read so I'm assuming you are using a turbo/notched xmember?

yes, notched Xmember. swapping that out for a turbo one was more effort then i wanted to put into this car.
Im using a 92 legacy turbo hitachi ecu.

as far as selling, make an offer. id rather keep it for next winter though.

Okay thanks. Seems like all the answers I was hoping for. One thing I was wondering was that you said you used the ej251 HG but I've read that you always want to use the hg for the block you are using? (i.e. EJ22 gasket)

Im assuming this is working fine for you but what is your take on this?

You can get a little more power/boost out of it with the current MAF with my MacGyver setup. It works best with slightly larger injectors but can be used with the stock ones. I assume you have a fuel cut defender already?

Put pipe elbow into the intake after the filter but before the maf. Have a short piece of hose with a ballco-ck valve and plumb that back into the intake after the maf but before the turbo. This is now a controlled amount of unmetered air. Watch the air fuel ratios at WOT and open this ballco-ck to the point that the AF is still safe. This will have to be balanced to the larger injectors so that the closed loop fueling is still within the ECU's fuel additive range.

Edit: lol nasioc is censoring ballco-ck

Kudos to your setup and thanks for providing the dyno numbers.

Haven't thought about doing anything to my Outback Sport but this......this is nice. I'm particularly interested in the 440cc WRX injectors and the 2.5 sohc heads. I think that is all I need now. Probably will PM you for some more info.

Again....cool setup.

Hello all, I'm Cam and I'm new to the world of Suby's and to forums, so forgive me if I'm trying to restart too old a post.

On that note, I was wondering why you chose the lower compression heads. I was under the impression that the higher compression and boost was why a turboed ej22 was a bit more potent? Or is that why you're not able to boost the 2.2's too much? Thanks in advanced, I'd like to slap a turbo in the 96 Impreza I just purchased so it'd clear some things up.

would i resolve the problems you ran into with the 2.5 intake manifold by using my stock 2.2 intake manifold parts?

This is what it's all about (to me). Low cost fun using good ol' ingenuity instead of spending metric tons of money on shiny stuff to get the same result.....

ROCK ON!!!!

Any recent pics of the motor and rest of setup? That pic isn't showing for some reason. This is for the late comers. Again, congrats on a nice setup.

I'm also using this build as some inspiration for mine, I'm going to use a 22e bottom with STI rods and pistons, and 25d heads with upgraded valve springs and cams with an 06 STI vf39 turbo.
I'm hoping to hit around 350awhp.

Good luck with your build!

Sounds fun. There are no STI pistons that fit the ej22. You will have to go aftermarket.
