Let it be the end-->Ej25 to Ej22 - which year to use?


Recommended Posts

I've been reading through pages and pages and can't seem to put a finger on what i really need. I thought that if we could get a jist of what all of us have done, we could determine which years are compatible with which ones.

 

I've got a 1999 Ej25 and want to swap an EJ22 in it. Which year will fit (regarding the transmission especially!)

 

So if you've swapped an Ej25 for an Ej22, tell us what year is your car and what year engine you put in it.

 

THanks!

1999 2.2 Liter Phase 2 Engine Enhancements (from endwrench article H-4 and H-6 service):

All 2.2 liter engine for 1999 are the Phase 2 design. The 2.2 liter Phase 2 engines are a SOHC design, with a newly-designed cylinder head. Changes in the 2.2 liter Phase 2 engines are as follows:

 

• The engine and transmission are fastened with six bolts and two studs.

 

You'll need a 99 or newer to bolt to the tranny. I've read here that you can get away with just 4 bolts but there is still an issue with the starter.

the 99 is a different animal being a year change and all. go ahead and search to read all you can about it first and then ask. we don't know your skill set or anything...are you doing the work, someone else?

 

search and ask specific questions about what you don't understand or are confused about. those of us that have done it and have typed essay after essay about it to try and help others are not compelled to help every time someone rephrases the same question.

you can answer that question easier than those of us that have done this. your eyes verses our memory! yours will differ from all 1998 and earlier....but i would not trust the model year alone. i would go ahead and count yours to be sure. who knows if there is an exact cut off date and if it's Dec 31 of the given model year. i would rather trust your eyes than any assumptions like that.

in 1999 it all depends on the transmission. some, a very few probably, 99s used the same trans as 98 TZ102Z2DBA. if you have this trans then you have 4 bolts. if they changed to the new engine and not the new trans, which i doubt, then they used 4 bolts on a 6 bolt engine.

 

so just read the trans number on the id tag or at the starter, if it ends in ...JEBA or JEAA or JECA then its the new 6 bolt. if it ends in ...2DBA then it's the old 4 bolt trans.

this is for 2.5L legacys/outbacks.

i've read lots of threads and they don't have all the information available.

 

I was thinking we could make this thread a reference from those who have done the EJ25 to EJ22 swap. They should tell what year they had in with what they replaced it with.

 

Would this be a good idea or no? Im not sure anymore, but lets try?

Once and for all, there is no starter bolt issue.

 

The bottom starter bolt IS NOT the same bolt as the engine to trans bolt.

 

The newer trans are jut like the older ones, the lower starter bolt is actually a stud mounted in the trans bell.

 

The 4 additional engine to trans bolts are jut that, additional.

8 mounting holes on the newer (6 bolt and the 2 bottom 2 studs)

 

Older style was 4 (2 bolts and the 2 bottom studs)

 

4 of the 8 hole in the newer style are in the same location, so they can be interchanged. The additional bolts are not nessecary.

 

If this didn't work, how do you think the guys running EJ22T block in WRXs bolt them up.

 

Again, there is no starter bolt issue. Lower bolt is mounted to the trans bell.

Thi is a 2000 OB tranmision. The arrow points to the back side of the lower starter bolt(stud) in the bellhousing. it's above and inset from the engine mount hole, not circled, but just at the tip of the yellow arrow in photo.

 

The holes circled in blue are the additional engine mounting bolt holes that are not on the older style. The 2 uncircled holes near top and the 2 stud holes(one obscured by hand) at the bottom are where the 4 pre-99 engine bolt holes are.
