2.2 or 2.5 swap?

[Bobbo63]

in the next couple of months i plan on swapping my 280k motor for a fresh one. Prolly gonna throw in a remanufactured motor and im torn between just throwing another 2.2 in there, or would a 2.5 be a better way to go? is it a direct swap? do all the parts interchange? im a wrenchahaulic... ive done plenty of motor swaps on other cars, but this is my first subaru. I know my way around an engine bay, i might not know the names of all the parts but i can generally figure out how and why they work. Any knowledge and or tips would be great.

Consider what you want to do with the car. If you are going to stay naturally aspirated, the general consensus on these forums is to stick with the 2.2L. It's an overall tougher motor and you won't notice the lower power and torque output compared to the 2.5L since they are both slow tugging these cars around.

 

This is why most blown 2.5L owners swap in 2.2Ls. As for the swap complexity, I don't have any experience myself but from what I read, it is very much a direct swap with minor differences in sensors.

What year is your car?

If your car has a dohc engine from 96-99. Then a 2.2 is a cheaper reliable option.

If you are going to replace the HG, the 2.5 DOHC is very reliable, plus it has 30 more hp.

its a 95

from what i gather... a 2.2 is the way to go

[Osei]

Yes, 2.2.

Note that you will need the y pipe from your donor unless you find a low mileage 95.

[Bobbo63]

why cant i use my old one?

[Osei]

95 was the last of the double port exhaust on 2.2. All others (96-99)are single port.

The 2.5 dohc has the dual port.

I'd stick with a 2.2 as well. It's a direct swap, except for possibly the exhaust header. You can swap in anything from 1995 to 1998, but the easiest would be another 1995.

Anything later than that and you'll need a single port header.

hey i have a old 2.5 1999 legacy burning alot of oil, and a friend has a 2.2 low mileage engine in his 98 legacy that he wants to sell. the mechanic here said a swap wouldn't work. sounds like this isn't true, but what other than swapping the motor itself would i need to do to have this work?

[HardyWagon]

oh and both are manual, no turbo, no AC.

you guys really need to learn to use the search function.

 

95 - 98 , (plus 99 outback and GT)

all ej22 and ej25 engines (plus 99 outback and GT) will swap,

with some conditions, such as:

 

1/ ej22s went to single exhaust ports in 96,

so if you are swapping in or out one of those

you will need the matching exhaust y-pipe for the new engine.

 

2/ ALL ej25 engines 96 - 98 (plus 99 outback and GT) have EGR (exhaust gas re-circulation)

only some ej22 engines have EGR, usually found in auto trans cars.

so if you need it, make sure you end up with it.

if you do not need it, it does not matter if it is there or not.

 

these are the two major conditions when swapping 95 - 98 engines .

anything else is very minor.

 

any questions?

@johnegg: I want to swap EJ22 into my 96 GT EJ25 wagon for more reliability. Do harnesses match up? I am guessing auto tranny housings match. Power not that important as reliability and bulletproof SOHC motor that I loved in my 99 Legacy Wagon.

 

What else should I worry about when buying JDM motor?

click the ''search'' button at the top of the page.

search for '' ej25 swap '',

enter my name '' johnegg '' in the ''user name'' window.

go to the bottom and click on the Search Now button.

 

you should get 112 threads .

i would read through the titles of the older ones first.

find one that sounds like it will answer your question.

there is a lot of good info there,

way more than i am willing to retype here.

and you will read answers to questions you have not even thought of yet.

 

 

you will find what engines swap.

which is the easiest to swap.

what plumbing problems are involved with the more difficult engine swaps.

what you should do to EVERY engine before you swap it.

what the most common cause is of a no start after swap.

jdm or usdm.

where to find good used engines for a good price.

how to find one close to your home.

tips on how to do the swap.

things to not do while swapping.

tools you will need or ways to work around that need.

 

so do the search and read up.

swapping in an ej22 into a ej25 car is very easy with no headaches what-so-ever,

if you use the right engine.

no different from pulling your ej25 and then reinstalling it.

 

good luck.

You could always do a Frankenstein motor.

+1 for the Franken Motor. I was thinking of doing it with mine
