What Engine is a direct swap without any troubles in my 2000 Subaru outback with 2.5 sohc

i have been looking on Ebay... But, really high mileage like mine i would hate to spend over 1000 bucks and have it installed and the same thing happen...

Mine is a 2000 Subaru Legacy outback Limited wagon... 2.5

i found a engine from a impreza 2.2 with 8000 miles on it... i was told this is a direct swap but i really don't know this is my First Subaru...

This car was bought new by my Aunt... she drove the car untill 167.*** miles when i bought the car from her i had EVERYTHING serviced... even complete new timing kit with all the goodies including waterpump and these parts was not bought from your average flip flop parts house i bought these strait from Subaru and with all the servicing i had all new hoses and even a new oil pump... so with that said... i was driving the car when it started knocking so i will take the blame for the blowed engine in which i was on the interstate at 75 on cruise control... so all the servicing was done right after i bought the car and i drove it never had a problem untill 189.*** miles when it started knocking and in which i immediately pulled to the side of the road let it cool and it was full of oil and coolant...

Chris, I'm sorry to hear about your engine issues. Would you be swapping the engine yourself? Would you be confident to do head gaskets? If so, you could basically find any '98+ 2.5L short block and bolt that up to your existing heads and wiring. If you only want to swap the complete long block, you can use a 2000+ SOHC motor out of any Impreza, Forester, or Legacy up to 2005. Beyond that, the heads change a little again. A 2.2L motor will swap in, but that might be a little more work. Again, if you were to do this, you would want to find a 2000-2001 2.2L motor just to be sure that all the electronics line up properly, and you will likely have to swap cam and crank gears as well. And Bob, Subarus never ever had two timing belts. They've always had one. The basic EJ motor hasn't changed much since its inception in 1990 either.

Thanks Jeff.!!! I would perfer a complete engine swap due to the mileage of the existing engine... the 2.5's are very hard to find in neck of the woods... have plenty 2.2's and that brings me back to my question... i was told that a 2.2 is a easy swap and is plug and go wiring... as stated this is my first SUBARU.!!! its been a awesome car... so i am looking for a plug and go option...lol if the 2.5 would be the simplest to drop in and go then thats the route i will take because i don't want to have to butcher my wiring or anything like that... Thanks for your Answer... anymore info will be greatly appreciated... O-and yes this would be a weekend project for me and my brothers...

Chris, No problem, sorry for the late reply. You can swap a phase 2 2.2 ('99+) into your Legacy with a few notes: 1) Make sure it's from an automatic and has EGR if your Outback has it, otherwise you'll always through a check engine code and you won't pass inspections near you if you have them. 2) You will need to swap the crank and cam gears from your old EJ25 over to the EJ22, as well as the sensors to be safe. One thing I would mention in going to the EJ22 is that while you will save some money and perhaps gain some reliability, you will definitely lose power.

from what jeff found I would just wate for the same swap,and not go all out with other than a cleanup, and to hell with pumps belts ect, too much time fresh oil filter trans fluid and go and plugs while out also,keep your old for futere parts.saves plenty

The only real belt work here would be two accessory belts and the timing belt, all of which should probably be replaced if a used motor were purchased anyway.

i guess then water pump if in their ,well if a nice car guess its worth it ,these newer cars are nerve racking

Thanks Jeff and Jimmy for your Response... BUT, i got more news today that the best route togo would be a direct replacement with a 2.0L (EJ20)...was told everything would be plug and go... i am being told so much i dont know if its worth it or not...

Chris, there is no EJ20 that is a direct replacement for you. Whoever is telling you that is completely wrong, especially if they are talking about the WRX EJ20. Those motors require a complete harness merge as well as changing out other parts like the crossmember, exhaust, fuel pump, etc. I am preparing to tackle this with one of my cars, and it is a very involved project. An engine swap of the same SOHC EJ25 or EJ22 would be much easier.

ok, NEXT!

I got one for sale are you still intrested??

Ashad, I'm interested. whats your price/year/mileage and service records for it?

while we are on the ej series on a 98 outback 2.5 dohc engine i snapped ahead bolt :/ my buddy grabbed a 05 2.5 sohc engine i didnt think it would work but its the same 2.5 ej. i swapped everything cam gears sensors are new i have a crank no start im beating my head agsinst the wall timing is dead nuts what am i missing?

there's spark and fuel those are not an issue someone said possible ecm.. another question iac is humming is it normal?

Your 98 ECU and wiring harness are not compatible with the phase 2 (99+) engines. Your best bet of getting things working inexpensively would be to use the short block off the 05 EJ251 with the heads from your 98 EJ25D. Otherwise, you will need to merge the wiring harness from your Outback with that of the 05 car in order to run the 05 ECU to control that engine.

Actully the 84 and eirlier EA engines did have two timming belts.but if someone was pointing you in that direction do not listen to them at all lol.

I have a 99 Subaru Impreza outback with a 2.2 can I swap for 2.5 directly using the same wires

You would also need to swap your cam and crank gears and sensors, but yes.

Provided it is a 99+ phase 2 EJ251. Personally, I'd stick with the EJ22, they're more reliable.

I hope someone can answer me this question. I just bought a 98 Subaru outback ( legacy) and the family/friends had it checked before sale as check engine light was on. I drove it and it died. I had it towed to a mechanic who said that the last mechanic who worked on it did not change oil or started and stopped as it was only a check. Long story short a rod shot through the engine block. My mechanic was sure Subaru would handle it through there liability insurance but they are not making it easy, so to get to my point while I am waiting for them to do as they should I am going to put in another engine ( used with hopefully low mileage ) Anyway I am having a very difficult time figure out what years are compatible. It is a 2.5 but I know with some adjustments a 2.2 could work I am just not sure what years will work? I assume others than just 98. Any help would be greatly appreciated. Thanks Katherine. ( also low mileage to me is 170,000 or around there and was wondering about what I should be looking to pay, so i dont get ripped off) Thanks again, i hope someone out there can help.

I have a 2.2 ej223 if i was to swap the motor out for 2.5 with the wires match or dose anyone know were i can get a used cylinder head for my motor

When swapping the motor, use the intake manifold, wiring, and cam sensors and gears to be completely sure. You would also need a dual port header the EJ251 cylinder heads. John, I can't quite follow what you're saying, but it sounds like you're expecting Subaru to fix a 16 year old car because someone neglected it and it was run out of oil? In any case, your car can run a phase 1 2.2, which would be a 93-98 EJ22. For a used motor, I wouldn't pay more than $400, especially if it didn't have a warranty.

my 1985 subaru dl has 2 timing belts

Jeff! You seem to have been through this before,Im looking to swap out a newer engine in our 99 outback.You said up to a 2005 shortblock would match up,Im a mechanic so can do all the work,will a later EJ25(?) dohc fit the 99 Outback if I just used the shortblock? I.E. could i match up my heads etc?THANKS for any help....Ebear

Have you considered just rebuilding your engine?

Ok, here's a good one for you.. I have a 2000 outback 2.5. Will a 02 6cyl fit/ bolt up (computer and w/h for both will be there) to mine. Or what would I need to do to get it too. I live in Ak and everyone has subi's, but the have like 5 shells in their back yard, so if they crash they just move the motor over, or they go for ~$1000 or better.

The shop said I threw a rod, and I've heard these motors have super tight clearances, is it possible I can rebuild it? Or is it basically scrambled eggs and I go with my above idea

the person is right about the old engines with two timing belts that 1800 ohc was used in the gl and dl from 85 to 90 and the loyal until 93 I think I had three of those cars my brother had one regards david

Balls

On the serious side. I have a 2002 forester that needs motor. I hate to part it out. Because it is black with leather and sunroof. Nice car. Anyway, which motor is a direct swap. Just 2001 and 2002. Or can I use the short block from the earlier years. Any help would be great. Thanks.

Archbold, if you can find a 2010 EJ series engine, it's likely that it will work for you. You can call Subaru of America to verify, their number is 1-800-782-2783. They are very helpful and will answer your questions. By the way, the reason I'm suggesting this year is that this was the first year that Subaru changed their head gaskets to a multi layered design and previously they had some issues in the early 2000s. And, it's before they introduced the new FB series engine which has experienced some oil burning issues. So, you're getting the best of both worlds here, newer gasket design with the old tried and true EJ25 phase two that had been in production since the 1989. That engine had a long run and by the second phase they worked out a bunch of bugs. Too bad they changed it for the Forester in 2011 and ran into difficulty. Even if you paid a premium price to get a new one, it would still have less expensive than a new car. Good luck.

I have an urgent question. I have and 06 turbocharged forester and my crank when bad. Got a another block froma 2000 forester. Can the block swap work without problems??

I just got a 1998 dohc Forester. It is knocking loud. It's not smoking or running hot. Can I use an older sohc short block with my existing heads, FI, ect. ?

OK, I just bought a 150k engine from a 1995 Impreza. Runs great The car is a rust bucket and has a strut tower through the cargo floor pan. I mentioned earlier my '98 Outback. The harness plugs look the same. I'm going to try a simple swap. I already have the '98 almost out but ran out of daylight. Going to finish it tomorrow.

I got the sohc engine bolted in after work tonight. I ran out of daylight. Tomorrow I will install the radiator, hook up the throttle cable, fuel lines, heater hoses and plug in the harness. I hope it works.

Hello I recently bought an 05 legacy 2.5i and come to find out today it's been swapped out with an EJ20. I have noticed there is little to no power till after I get to 30mph it has the stock transmission that the 2.5 was bolted to is there any problems that come from this type of swap I should look for? Also the mechanic that looked at said it looked like they put the 2.5 heads on the ej20 block could this cause the sluggish issue?

I have 2002 subaru legacy staion wagon (my first subaru),i belive with 2.5L and its Automatic. I bought this car for project i would like to build this car for family and my hobby, next year im going to fix the rust and repainted before i will be doing a swap.. And here is my question, what can i put in to have more power?? What engine will be the best and tran? Money is not an issue, i just dont want something that is to diffecult to do ..

yes there is a ej20 non turbo jdm engine that is a direct swap into the 2000 sohc 2.5

ej20 non turbo jdm engine u would have to use the cam and crank pulleys and most likely intake off your 2.5 sohc

Alrightt :) thankk youuu, i will try to get that engine :)

Just to know , is there any other engine that fits easley besides ej20 That will fit in 2002 legacy wagon ??

I have find ej20 engin, by the way does it have to be non turbo??, and what year ej20 should i get??, wiuld it fit easly in to 2002 legacy ??

Will the 2000 wiring harness and ecm work with a 2005 and up engine? Thanks

I have a 99 legacy outback limited that I removed the 2.5 dohc and installed a 99 2.2 phase 2 motor from a impreza. Problem is the 2.5 intake with egr does not fit. The 2.2 intake does not have egr. All intakes before 99 have ports are too small. would a 99 2.2 intake with California emissions have the egr. Any suggestions?

I have an 03 Baja, recently did a swap and put in a EJ20 from japan, intale, cam, flywheel all tranfered of from the EJ25 that I blow up. My question is.... Can I use a EJ25 from a 07 Forester for my next swap? and can I use the tranny out of the Forester too?

Hey yall. Listen just put a new 98 2.2 motor in 99 Subaru Impreza outback sport.. Problem all the intake dont match99. So I left that alone. Decided to just cut the injecter wires and hook up the connectors from my 98 harness hooked up to 99 wireing. So I did all that now tryied to start car car wont run. Went threw all the wiring to find out I'm not getting signal to the injectors. Can I hot wire those injecters only because they are older that the 99 injecters. The 98 injectets get gas from side . My 99 get gas from top. Either way ill get her running just was hoping someone had tho problem befor and could just point me to the right wire to get that signal.

The tranny bolt up. Ej22 will bolt up to automatic and five speed.on the 98 block it will still bolt up mins 2 bolts. One bolt for the starter will be different that's the 98 block. Its amazing how different the blocks r from being a year apart. That's also the same year they made mods to the motor.the ej25 is the same. I was gonna get the ej25 but then I had to change the ecu to I wasn't in the mood for that.

Your idle air control is different on the 98 2.2 also.Am I correct that your 99 imprezza outback sport had a 99 2.2? The 99 2.2 is gen 2. You can put 99 gen 2 heads on the 98 block, use gen 2 intake, and 99 2.2 timing belt, and 99 timing covers. If you need parts I just did the opposite and have gen 2 heads with 118k, timing covers, timing belt. Good luck.Rick

I figured something was off cause I hooked all the old stuff up computer was fine. I have the intake. All I need now are the heads I have everything else. If ur selling the heads let me know. My other heads are beat. Pistons bent all the valves. It will be cheaper to get new heads for car. So let me know. Thanks Rick.

Def let me know. I'm gonna check with my boy and see if he can still work me deal for valve seat and springs. U still let me know.

Sorry to beat this issue further, however upon reading the thread without an answer I feel I can now ask lol. Engine tranny swap info needed! 2000 legacy outback had 290k when the tranny died 2.5l automatic. I purchased a donor car, a 2002 Subaru imprezza outback, also a 2.5 automatic. The donor Is my preference, however it was In an accident in which the frame up front is a little bent. Safer to swap into the legacy or revamp the imprezza? If the answer is imprezza could I just straighten it out, weld reinforcements in and get a new wheel and dash and seatbelts(air bags went off and belts are locked) is the imprezza motor and tranny a direct swap into the legacy? Must the wire harness go with? And must anything else be swapped? Thank you in advance, I look forward to doing g SOMETHING with these Subaru's

Winters aren't the same with out a subie

Switching between 97-99 DOHC heads are all interchangeable,, if you wanted to put a 2.2l in the outback as a replacement use your 2.5l intake with the EGR u need and the cam sensor from your DOHC and it will work.. No need to splice wires us your Intake with your harness.. Any 2000-05 legAcy or forester engine will be the same 2.5 SOHC , consider emissions and EGR difference but block are the same...

I have a 1999 Subaru Outback Impreza 2.2 I need a motor what is compatible?

hello there, maybe someone can help me out. I have a 1998 legacy outback AT. motor at 210,000 miles started knocking. whats the newest motor i'd be able to directly drop in and bolt up?

Got a question if someone can help I got a 2005 subaru outback with the 2.5t trans mission is getting tired would a 2.5 non turbo trans work for it?

A knock nois don't mean it engine is bad if the knock at front driver side change belt tensioner makes knocking noise after change it then race the engine if it not shore watt tensioner it's the top right front let know how it worked out for you abrahamparra460@gmail.com email me I'm a pro mechanic

if you are simply swapping an ej25 (2001) into a 2000 subaru (had ej25 & auto trans, same as the other) do you have yo swap the computer too?
