I downloaded the PDF. Interesting read. I am thinking of making the Smack Booster and hooking it up to the BRAT. Will see if there are any differences in mileage. BW

almost done rebuilding my EJ22T. Going into an RX FT4WD D/R tranny. pull up a seat, pop a cool one and get the popcorn out.... it's either or :-\

Donor is an EJ18 FWD Impreza. I am using the stock EA81 4 speed tranny no error codes. I get an intermittent CEL blink b/c i spliced the temp wire to the temp gauge. VSS is hooked up to the reed sensor in the cluster. Exhaust set up is the same. I am probably going to disconnect the battery to reset the ECU. It's not predictable as to when it cuts off. Speed varies and conditions vary. The only constant factor is that I usually am just done with accelerating and I move it to neutral to coast. It happens intermittently. Enough to be bothersome but not enough to be a problem. I usually look at the tach when I do decide to coast so I can catch this. Yesterday it happened once on my 25 mile drive to work, and it didn't happened at all going home.

hmm.. possible. Will see it I can splice something in there. I guess I can hook it up to the brake pedal since I do not have a clutch switch.

I am having a problem with my EJ BRAT. Sometimes when I am on the freeway and I shift into neutral and coast, the engine will shut off. I then have to bump start it. What could be the cause of the shutoff?

I am doing the reverse. I have a 2k OBS and I am putting in a 98 EJ25 DOHC. For you, the engine is mechanically the same, the problem is the sensors in the different phases. If you can get the entire motor, harness and ECU, The 2k harness can be trimmed and thinned down to just the essential engine management and ECU wires, then it can be spliced into the 98 harness so that your fuel sensors and all of the other OBD2 stuff will be hooked up. I can help you with this part or do it for you if you want. Give me a PM. BW

tony... I can bring by my "hammer of Thor". What time are you guys going to get started with this project? BW

http://www.redbullflugtagusa.com/Portland2008/default.aspx Someone should make a flutag out of old subby parts!!!!!! So does this post belong in transplant, racing or ot?? BW

Send me a PM and we can talk. here's some info from a thread I started. http://www.ultimatesubaru.org/forum/showthread.php?t=70262 BW

take the el camino to a dry cleaner and have them shrink it... then you will get a brat. But seriously. It's kinda up to you. Sounds like that are both potential money pits. On a different note, what part of AZ are at now? I might be traveling there sometime soon with Crabman to pick up a motor. Might be able to transport some parts to you. Let me know what you need and what you can afford. BW

yeah. you could do that. If you had an SPFI, You would need to put a disty on the back of the pass side head, then use a coil to get power to the plugs, You will need the SPFI MAF sensor. Then you would have to figure out a way to get the SPFI throttle body to connect to the EJ intake manifold. Then it's just a matter of the EA computer being able to take in all of the readings from the various sensors on the EJ motor. You can do it for laughs and giggles, but if you are really that set on diving into all of the wiring work, why not just trim your EJ harness and call it done? BW

he's just bitter and clinging to his guns and his religion (subaruism)

Welcome to the board. The 83 hatchs only came w/an EA81 carbed motor. Poke your head into the engine bay, see if you can find an engine stamp. If it's an engine swap it should read EA82 on it. Your distributor should by in the rear engine on the driver's side. There should also be black timing belt covers If it has the distributor in the front of the engine, then you have an EA81 that was converted to by fuel injected. That would be really sweet as this swap has only been done a few times on this board and all of them within the last few years. What part of california are you from? BW

Local PAP had a 50% off sale. Picked up a set of axles. Now for some axle surgery. Also I swapped out the front Outback struts for my old OBS struts. Lowered the BRAT by about an inch up front and gave it a really nice rake. Best of all it made the drive line much happier. CV's now rest about 5 degrees down when sitting flat. Have to figure out how to get them to sit level, but that's probably going to take a taller lift block. BEST of all, I got rid of this nasty front end vibration I was getting and the off the line wheel hop. BRAT drives nice and accelerates great. Will upload some pics of the carnage. BW

Yep. problem is the EA81 control arms are too short. The only stock option that will work with the EA81 tranny is the FWD impreza axles. But you would have to extend the control arms. Regular XT6 axles might work in conjunction with the 5 spd swap and using EA82 control arms. The EA81 engine crossmember is a bit narrower than the EA82 So custom axles or extended control arms. (any modifications are the responsibility of the modifier)

The EJ trannys have 25 spline stub axles in the front. If an EA82 25 spline cup can fit in an EA81 23 spline DOJ joint then it will work or you might be able to use an EA82 axle outright if it isn't too long.

I would love to get my hands on a marlin camp 9 or camp 45 but those are pretty hard to find. I do have a marlin papoose. It's a take apart .22 The barrel unscrews at the end of the receiver and then it all goes into this nice carrying case about 18 inches long. I have yet to take it out camping with me, but mainly b/c I live in SoCal. BW

It also doesn't hurt to have some extra axle parts, DOJ cups, axles cages and balls. rear diff stub axles would also be nice. I luckily had my c-clip plier in my tool box when I broke down in the Mojave. This will probably be a permanent part of my off-road tool kit.

Ok so synopsis of the two threads is that with the phase 2 2000 EJ22, the earlier EJ's will have sensor issues and may require extensive harness rewiring to get it to work right. The EJ18 route was a bandaid fix. bolt up the 1993 OBD1 EJ18 and then rebuild the 2000 OBD2 EJ22. I have a EJ18 in my garage and I also have a complete harness and ECU for it. I could strip the harness and then use the EJ18 harness and ECU to run the EJ18. This would be a similar set up to the EJ swaps on the EA cars. Like I said this would allow for me to drive my Impreza while I rebuild the engine. It will either be a stock rebuild to a High Compression Frankenstein EJ25 shortblock w/EJ22 heads. The EJ25 route is a more permanent route. Bolt up the 1998 EJ25 DOHC and then use the existing 2000 EJ22 ECU and harness to run it. From what I have read and discovered, 1) this has rarely been done and 2) there is no real success story with this working. The one way that people are able to make this work is by running the engine with the EJ25 ECU. EJ25 has a MAF sensor and the 2000 EJ22 has a MAP sensor for air flow measurements. I can get the ECU from the seller, but he is keeping the harness for the swap. I might be able to hack the 2000 EJ22 engine harness to work with the EJ25 ECU, but I am not even sure that the connectors will plug up. and it would take a long time to get it running. if I can get the Rx moving by the end of the month, there might be hope of going through with the EJ25 route. Otherwise the EJ18 route looks like a go. So here is what I am going to do 1) hack EJ18 harness 2) pull EJ22 and swap in the EJ18 3) Tap the EJ18 harness to the OBS harness for power. 4) source headers for the EJ18. 5) repair the EJ22 and then put it back in.

s'ko1998 EJ25 engine and tranny swap into 2000 EJ22 OBS from what I read, the ej18 is not going to work w/o some issues. Found a EJ25 for a good price w/a 5spd tranny. my tranny's synchros were going out so it's a good time to do both. Here are a few questions. 1) EJ25 is that pretty much a plug and play for the EJ22 ECU? 2) The new tranny has a hydraulic clutch cable do I need to retrofit the hydraulic system into my car? Thanks for the input. BW _____________________ mellow65 if it's a dohc ej25 then it should be more plug and play. just think of the outbacks to ej22 swap but in reverse. you do still need a duel port header. if it's a sohc that's a whole different ball of wax. i put one in my 90 legacy, but i have no IAC. it's just something I live with because it's my rally car and cold starts are the least of my worries. it's just because the sohc ej25s have the IAC on the throttle body and the ej22s have them on the intake manifold. the IAC on the sohc ej25 don't even have close to the same plug (mine didn't because it was OBD1, may be different on OBD2 ej22s). there is rumor that some JDM wrxs had intakes that bolt onto the sohc heads and have the IAC mounted on the intake. I wasn't ever able to find one and check for myself. The other path to try is to use a ej18 throttle body because it has the IAC mounted on the throttle body. I was going to try this route but I never could find one to mount on my car. The plugs are the same on the ej18 IAC and the ej22 IAC I just don't know if the computer would run it. As for your tranny, i have found that the NA trannys (and maybe turbo, just don't know) will take your cable clutch shift fork. i had a cable set up on a 03 RS tranny in my 90 legacy and it worked fine. if you do get a 2.5 motor you might just think of doing the 2.5 block 2.2 head hybrid motor. lots of people have done that and seem to be real happy with it. that is if your heads are in good shape. but even to have them redone i found someone here local that would fully redo both for under $150, so it's not that bad to have them redone. good luck:) _____________________ s'ko Quote: Originally Posted by mellow65 if it's a dohc ej25 then it should be more plug and play. just think of the outbacks to ej22 swap but in reverse. you do still need a dual port header.

There is no problems with the motor. I will be taking the heads off and replacing the head gaskets to make sure they don't pop. Sounds like this is going to be the new engine for my OBS. _____________________ s'ko MORE good news. According to the previous said that he has already done the head gaskets. woo hoo.. OBS will rise again. Now I have a spare EJ22 n/a block I can rebuild and play with. looks like an EJ22 will be residing in my BRAT in the near future. BW _____________________ grossgary awesome - new headgaskets! AH!!!! you need to remind people of the years of the stuff you're working with. there are significant changes through they years and when doing a swap it's not enough to say "EJ22" or "EJ25". as long as SOHC and DOHC EJ25 intake manifolds are interchangeable that's good (and i think they are). the bellhousing changed around 1999 - so you'll be putting a 4 bolt to an 8 bolt i believe. but that can be worked around if that's the case. most significantly because this is a 2000 you're going to have "special considerations" that don't apply to earlier EJ22's...hence my remark about verifying what you're doing earlier. i think you'll need to retain the EJ22 cam pulleys, or at least the one with the sensor triggers on it. normally you'd swap all the pulleys over if it was SOHC to SOHC...but being DOHC i'm not sure. _____________________ mellow65 Quote: Originally Posted by grossgary as long as SOHC and DOHC EJ25 intake manifolds are interchangeable that's good (and i think they are). they aren't, they moved the bolt holes. _____________________ s'ko Quote: Originally Posted by mellow65 they aren't, they moved the bolt holes. I am getting the complete engine. So I will have intake manfold, injectors and all of the other fun stuff that comes on an 1998 EJ25. BW _____________________ grossgary i don't know that the 98 electronics are compatible with the 2000 stuff. do you know if the 98 stuff (Phase I) will plug in and work with the 2000 (Phase II) stuff? there's not much information on doing swaps across Phase I and Phase II, so it's a mix of related knowledge to get you there. what i'm sure of is that it is not like other EJ swaps. swapping engine and trans sounds like a great plan. you'll just need the rear differential to match since it'll be a different gear ratio. the RS should probably be a 4.44 gear ratio, so you'll need a 4.44 rear diff to swap in too. actually i think i have a 4.44 rear diff i'd sell if you need one. the 2000 vehicle is not going to be compatible with the RS EJ25, i know that for sure that it will not be a drop in and plug and play scenario. not sure if swapping ECU's would work (it does on 1998 and earlier...not sure about 2000's). if the wiring didn't change this will work. i have a DOHC ECU i could sell if that's the case. all you need to do is look at the wiring diagrams for a Phase I DOHC EJ25 and a Phase II SOHC EJ22 (or Phase II SOHC EJ25 will be the same). i have the former but not the later. i'll send it to you if you need it, or post here. no matter what you do the DOHC cams will not work with your 2000 EJ22 vehicle....that's why trying the EJ25 DOHC ECU might be worth looking into. then everything becomes plug and play. _____________________ grossgary Quote: Originally Posted by mellow65 they aren't, they moved the bolt holes. great information mellow - i was wondering... that rules out the easy solution.

BW i got that i was clearing it up for grossgary. this should be a pretty strait forward swap unless they changed harness plugs along the way. also that should be a fun little car after you are done. i love my ej25 powered legacy and got to think a 2.5 obs would be even better. one thing that i ran into was the grade of fuel i had to run. because of the bump in compression and the fact that ej22 ecus have the second steepest ignition curve (only to be out done by the ej18) i had some detonation in the higher rpms. the knock sensor took care of it but it also sucked my power in doing so. my solution was to run super and it took care of it. but i'm using mine in a rally car. with normal driving i didn't feel any loss of power. _____________________ mellow65 Quote: Originally Posted by grossgary great information mellow - i was wondering... that means you can't bolt your EJ22 intake to the EJ25. the issue isn't whether or not you got the intake manifold...intake manifolds are everywhere and easy to find. what matters is that the electronics are compatible between these two engines. if the intake manifold bolts up (which we now know it doesn't), then it's very easy....just bolt your Ej22 intake onto your EJ25 engine....but we just found out that's not possible. so now you hope the electronics didn't change. having the intake manifold with the engine doesn't mean anything. i can go buy hundreds of different motors, ford, dodge, ferrari, with intake manifolds but if the wiring and plugs don't match up it doesn't matter. hold on to your EJ22 intake wiring harness after you pull the motor and try to keep it in good condition just in case you have to try and install it onto your EJ25 intake manifold. but the nice thing is subaru followed the K.I.S.S. "keep it simple stupid". so many things are interchangeable on the ej series motors. this is why it was crazy easy to swap a 99 motor into my 90 legacy. sure there were a couple little things to overcome but nothing was crazy. even if he has to pull the harness off of his 2.2 and snake it onto the 2.5 it still is easy. that part of my swap took all of 5 mins. or even if they changed all the plugs and sensors make it work. the only part of the 99 ej25 electronics i am running on my car is the injectors. nothing else. ever other sensor and plug is strait off a ej22. and i only had to do that because i had a phase 2 ej25 and they changed damn near every plug and wire between the phase 1 and 2 ej25. _____________________ s'ko Thanks for all of the info. I think that I am going to go the route of taking the EJ22 intake harness off and using it on the EJ25. I mean all of the sensors should be there, cam angle, crank angle, knock etc. It's just getting the signal to the correct pin in the ECU. If I use the EJ22 harness I will not have to play with wires, I will just have to make sure that the appropriate connectors are plugged into the sensor. I have diagrams for both engines. I need to go over them and compare the two. Hopefully this will be a one day, at most a two day weekend job, b/c I am going to borrow a neighbor's garage space to do it. Will keep you posted

OBDI EJ18 long block into OBDII EJ22 car S'ko For those who don't know, I spun a bearing on my EJ22 motor and I need to get this car running. the EJ18 is only temporary until I get the EJ22 rebuilt. So the main issues that I see right now are 1) Need dual port exhaust header. 2) Need to figure out how to bolt on a knock sensor anything else anyone can think of? Thanks BW ____________________________ mellow65 maybe egr not sure if yours had one or the 1.8 had one. the coolant cross over tube (thing under intake). some of the newer stuff went to a single temp sensor and the older stuff had two. in my swap i just swapped the cross over tube from 2.2 on to (in my case) the 2.5. it bolted up and i didn't need to worry about swapping the sensors. your cam and crank sensors, and your oil pressure sensor. but those are an easy swap. as for your exhaust, snag anything from a obd2 ej25 or very early 2.2. they have the duel port and the crazy turn in the exhaust that should bolt up. if you were closer, i have one just sitting in my garage i would let you use. i'm not sure if the 1.8 had a threaded hole for a knock sensor, but i have seen guys move them to the top of the engine side of the bell housing. can't think of anything else right now. i will put more if i can think of anything. good luck. ____________________________ grossgary it would help to know what year EJ22 you're talking about and whether it's from an auto or manual. the knock sensor will bolt right up. the hole is there and i think it's even threaded (at least on mine it was). you'll need to fabricate a block off plate for the hole in the passengers side head exhaust port. i cut one out of steel plate, used the original EJ18 gasket that goes there and coated it with sealant on both sides. bolt the EJ22 intake manifold to the EJ18. i think i covered everything in your other thread. ____________________________ subaru360 I have a few of the dual port headers from a legacy if it's the same and you need one. ____________________________ grossgary Quote: Originally Posted by subaru360 I have a few of the dual port headers from a legacy if it's the same and you need one. that will work, i've bolted EJ25 headers right up to an EJ18. no problems, direct fit. and i've also had a set of headers shipped before. tape some cardboard to them and slapped a label on it. cover any sharp edges and wipe off dirt/oil. ____________________________ s'ko 2000 OBDII motor 5 spd manual. Subaru360 pm'ed you for headers ____________________________ grossgary Quote: Originally Posted by s'ko 2000 OBDII motor oh crack. i didn't realize you were working on something that late, this will likely have some issues. that will have an EGR valve though, so that's easy enough. the intake manifold changed on the EJ22 at some point and won't bolt up to the EJ18. i think a 2000 might fall under this umbrella. so your 2000 EJ22 intake won't bolt to your EJ18 engine. if the 2000 intake manifold won't bolt up to the EJ18 you're next option is to swap the entire 2000 wiring harness onto the EJ18 intake manifold. a bit of a job but not out of this world...if everything is compatible which i can't answer but i would think it's workable at least. the EJ18 manifold is a messy animal so you might play with the idea of finding an earlier EJ22 intake manifold and swapping the 2000 intake wiring harness onto that. so......put your 2000 intake manifold wiring on a 95-98 EJ22 intake manifold and bolt that to your EJ18 - just an idea. on earlier...say up to 1998 or so...you can swap EJ18,Ej22,EJ25's and not swap cams. but on the later models...i think your 2000 will be one of them, you'll likely need to retain your cams. so you'll need to bolt the 2000 EJ22 cams to your EJ18 engine. this is...speculation based on experience if that makes any sense? i haven't done this exact swap nor do i recall exact years and difference, but i'm pretty sure this will be the case for an EJ18 swap into a 2000 EJ22. ____________________________ s'ko So what you're telling me is that it might not be a simple 1 day swap. hmm.... that sucks. BW ____________________________ grossgary Quote: Originally Posted by s'ko So what you're telling me is that it might not be a simple 1 day swap. i'm leary of it being a simple one-day job. i think you'll find you have the newer EJ22 that is not the same as 1998 and earlier EJ22's and EJ18's. if you find out they are different then the way to make it quick is to get a 2000 intake manifold (just like yours) or just the wiring harness if someone has one and try to swap it to an EJ22 intake of an earlier year that will bolt to your EJ18...of course you'd hate for that not to work. basically you need to find out if your 2000 wiring harness will easily swap onto an earlier EJ22 intake (1998 or earlier). i would think it does, but can't promise that. the main thing to check is the fuel rails and fuel injector connectors. you could probably bolt your 2000 EJ22 heads to the EJ18, but that's a can of worms i don't know about. and i wouldn't want to go through all that, then you need to check and mill the heads, buy head gaskets and adjust the valves. more money and time. ____________________________ s'ko Quote: Originally Posted by grossgary you could probably bolt your 2000 EJ22 heads to the EJ18, but that's a can of worms i don't know about. and i wouldn't want to go through all that, then you need to check and mill the heads, buy head gaskets and adjust the valves. more money and time. I do plan to use a ej25 shortblock and make a high compression frankenmotor. I just wanted somthing that i could fix quickly and be able to drive it. If I this is going to be more complicated than a long block swap, I am going to have to hold off until the RX is out of the garage. I am really close to getting it all back together. BW

Yeah. It was pretty hairy at time. Being paranoid that with every click and clunk the car made. I had some time to process everything while i took public transportation to work today. (it's been a bad subaru month for me. see http://www.ultimatesubaru.org/forum/showthread.php?t=87121) I think that for the front, I need to reduce the CV angles. I am currently running a 3 inch lift block w/Outback struts. I have a set of OBS struts and I will put those in. that should get my drive lines back to a more usable angle. For the rear, I am going to put in some bump stops to limit my upward travel and some limiting straps to reduce my downward travel. What is ideal for a soobie with stock EA81 rear axles? Is there another axle option I can use with longer travel? Hopefully the next outing will be closer to home and I will have these problems ironed out. I will also know to bring extra axles with me. BW

was an utter disaster..... I went camping with Tony (aka Crabman) this last weekend. We started off bright and early on Friday to miss LA traffic. Things are going great. I have this front end vibration that i need to resolve, but things were going well. Well about 10 miles from the turn off.. I suddenly hear a crunch and some really nasty noises and I lost forward momentum. Engine is revving fine but there is no power going to the wheels. I pull over and I look at the engine and I notice that the engine is covered in grease and the driver inner boot was torn. I look at the axle angles and it was pretty flexed out. The might be the front end vibration. The weight in the back of the BRAT had lifted the front end and the axle angles were maxed out. I think ok.. No problem, put it into 4x4 and keep going. We get on the trail to the campsite and it turns to gravel. I am driving it pretty hard and it feels great. With the power going to the rear wheels it was drifting like mad. I am thinking this is great!!!! Then DISASTER.... hear another crunch and rattling metal sound and I again loose power. So I am thinking I am completely SOL. I manage to coast the BRAT the campsite and I take a look at the rear axle and pulled apart b/c the suspension travel was too much and it over-extended. Luckily I had my circlip pliers and was able to rebuild the axle. I spend the rest of the weekend relaxing and hiking. No 4 wheeling like we had planned. So we leave today and I am taking it really easy getting out of the campground. Then I drive it up the last hill and BOOM.... rear axle blows up again. This time spilling the balls everywhere. I manage to recover 3 out of 6. I get towed out of the trail by Tony and to a flat spot to figure something out. I am 170 miles from home and I have 1/2 my balls. I just got premium AAA for this trip and I try to get them to come out and give me a tow back home. They tell me.. since you just signed up, it takes 7 days before your premium membership goes into effect. I try to fight it but they will not budge. I try calling some people and they can't help me out to me. So I look at my axle and the three balls and I put them together in opposing sides. I manage to limp it down the freeway 36 miles to Barstow and go to a Autozone to get grease and other things. After putting a bunch of grease in the axle and secure it with a hose clamp. I limp the car home the rest of the way. So yeah for my Macguver powers, but boo for the BRAT. I will need to take a look at what went wrong and how to fix it. Will take carnage pics. BW

Thanks for all of the info. I think that I am going to go the route of taking the EJ22 intake harness off and using it on the EJ25.
