why would you put a ej18 intake on a ej25 when you can use the ej25 intake and an ej18 throttle body. the intake wiring had to take me all of 30 mins to do and that included zip tieing everything in place. it doesn't get much easier then that. there is no large hurdles to overcome just some little ones. but for simplicity yes just putting a ej22 under the ej18 intake would be the easiest, but why take the easy route.

check out my write up http://www.ultimatesubaru.org/forum/showthread.php?t=83839 it's pretty much a bolt in thing. you would need to reuse your wiring from your motor and put it on the new motor. assuming you were just going to run the 1.8 ecu.

when you say fun, are you including it sitting in my driveway while i make stuff fit for your car. nothing like having a buddy with a welder and metal working skills, hmmm i wonder who that would be.

i'll be there, i wont be representing the subaru world this time, but mitsubishi truck world. yeah i like to mix it up see you guys out there

from what i have found there is no difference between a 2.5 and 2.2 flywheel. i can't say i have ran a 2.5 flywheel on a 2.2 but it all bolts up. and the clutch parts are all the basically the same with the NA stuff. like i'm running a 2.5rs clutch on a 2.2 flywheel and it's working just fine. i know it's not the exact answer your looking for but at least it can give you a place to look. find someone with a 2.5 flywheel and do some checking with your 2.2 next to it. and if it all looks the same order you up a flywheel for a 2.5rs, which there are tons out there.

99+ forester and impreza and 00+ outbacks have the phase 2 ej25. as subaru360 said really the main differences through out the years were the crank and cam teeth numbers. what i would do is take the new motor down to a long block. take the intake off your old one and just bolt it on. then really you need to count teeth at that point on the cam and crank gear between both motors and see if they are the same. if they aren't then you need to swap cam gears and crank gear and i don't know about the different water pumps. maybe between turbo or not but from what i remember the main difference was the thermostat housing was different between the autos and manual. the autos foresters had extra nipples to run over to the factory oil cooler. but all that can be moved around to where you need it to be. but as you get playing with subarus you will find everything fits everything. ej motors bolt into anything that had a ej motor. hope that helped

the impreza didn't get a ej22 until they swapped over to obd2. in the 95 impreza the ej22 was obd2 a full year before it was required. aparently the obd2 plugs are the same, but the obd1 stuff is way different.

yeah you had quite the dryer course then we did. what a sloppy mess, took me like an hour to get most of that mud off. but still had fun. third is better then nothing.

from what i have found it's really the other way around. the ej18 has more crap then the ej22. and even if i sit down with a pin out of both ecus they seem to call the same thing something different. so it's just a pain to sort out. but it's just probably going to take me sitting down with the car and a ohms meeter and tracing wires. i was just hoping i could find someone that took this on once before.

has anyone taken on the challenge of repining the ej18 ecu plugs to work with the ej22 ecu. yes i know i can put a ej22 right under the ej18 manifold and motor down the road. but i'm looking to get that knock sensor that the ej22 ecu offers that the ej18 does not. i figure there has to be pretty much the same amount wires between the 2. i know the ej18 has a couple things the ej22 doesn't, egr, some other air bypass solenoid. but has anyone tackled this idea. or am i just going to need to strip everything down and lay in an ej22 harness to get it right.

well i might not be making it with the impreza. found a stripped spark plug hole. but as i was trying to pull the plug out it fused its self into the head so i can't even take it out now. so it's running better then it has. so i might just say screw it and run it anyways.

i have heard of guys running a mega squirt stand alone ecu for timing alone. and they are cheapest stand alone ECUs that i have found. But it still would require some tuning later on to get your timing right.

i had them made. shawn told me at the WCSS as long as i wasn't trying to make money I could have my own stickers with the site name made.

i knew ed was going to chime in about the wagon. well i will see you at the rally cross in it. got to break it in properly.

mine stems from a car i had. i had a yellow 65 mustang. so you take mellow yellow, and the year and end up with mellow65. i dont have the car anymore, but the name has stuck around.

had to add the most important part

ngk all the way. i have had a many subarus have the surging under acceleration problem. Most of them were traced down to cheap plug wires. a good set of ngk plug wires and plugs fixed all my surging problems.

why must i keep bringing subarus home to nest. well thanks to sgregory i add yet another subaru to my pile of subarus. ok i really need to start figuring out what the hell i'm going to do with them all. current count of subarus = 4 (not my highest ever, but i was down to 1 at one point) super clean wagon to do ????? with. but i have ideas a brewing.

well that's good. although, you know somewhere someone has done it like this, you just know it.

i want to believe this isn't true, but after reading it, i just don't know. http://www.pirate4x4.com/forum/showthread.php?t=763645

ok yes i forgot about that one, but i was trying to stay within reality for pity sakes

then no he has nothing fancy. but when people start going off on crap like that i just let them run on and on just to see how much of a hole they can dig them self into. just like this guy one of my favorite, "i know nothing about cars but it doesn't stop me from talking big" videos ever.

it's kind of how you look at it. first yes the 2.2 and your 2.5 are overhead cammed. technically he does have a dual cams, because there is one for each head. with that then the older 2.5s and newer turbo stuff would be quad cams. but no there is no 2.2 with dual over head cams on one head, not unless he put them there by doing a head swap. which i'm pretty sure he didn't cause of how you describe the car. but you never know.
