Dual port head EJ22

that looks completely different then mine...... like wow

There is a version of the EJ22 with dual port heads, I know someone local with one. I believe it was only for 1 year.

mine is also a 96 2.2 and is single port. maybe the 96 outbacks 2.2 is different then other 2.2s. Hmmmm interesting

My 96 outback has single port heads. Sucks cause i was getting ready to buy eekays header

Phase 1 vs. Phase 2. Phase 1 EJ22E (two-port) ran from I believe 1990 until '97, when they switched to the Phase 2 EJ22 with single-port heads, the crank thrust bearing changing position, the compression ratio being bumped and so on. Of course the 'cusp year' cars often get strange combinations of parts in them as things are often introduced as a running change. For example I once had a '00 Impreza that had the '00 engine and interior but '99 brakes.

That still doesn't make sense because every other EJ22 from 96 I've seen was single port.

It does make sense when you see how a production line operates. Yours might be an early build and you have more of the leftover '95 parts. Your VIN number should offer more clues. Engine code for the twin-port model is EJ22E btw.

Yeah generally if they are trying to remove large stock of certain parts they'll do weird things to achieve that. In your case they may have done exactly that

95 was the last year of the dual ports. And even then that is not a factory header. Or it sure as hell doesn't look like it. A dual port header is all one piece.

 

My 2.2 put more low end torque down on a dyno then a 2.5 until 3700rpms.

Looks like a subaru part number. Lol.

 

However I have removed a few different ones before and have yet to see a dual port header ever look like that one after the shields were removed.

 

This is new to me.

from another ej22 thread

 

the ej22 didn't go interference until the 97 model year., even though the exhaust ports changed in 96. they went interfernce when they squeezed a little more hp out of the engine in 97 which is the same time they changed from HLAs to solid lash adjusters. i hear the pistons changed in 97 making it interference.

 

EJ22s - new in 1990 MY

90 - 96 MY are NON-interference .

90 - 96 have HLAs.

90 - 95 have dual port exhaust heads.

95 - 98 have EGR on the auto trans cars.

96 - 98 have single port exhaust heads.

97 - 98 are interference and have SLAs.

99 - 00 are phase 2 engines and i'm not sure.

EJ22s - ended in 00 MY.

 

there have been a few situations, or at least i have heard there are, where a late 96 may have SLAs and be interference, or an early 96 might have dual port exhaust heads, but that is just a case of them ''using what you have''. i don't believe there are enough of these car / engine out there to justify a discussion. unless you happen to have one in need of repair.

.

what stood out to me in the pic was the header. it is different from the dual port y-pipes i have seen on 95 ej22s and 96 - 99 ej25. (all the y-pipes i have ever seen are all one piece. that one seems to be in 3 pieces, if the other side is the same as the one in the pic.) could this ej22 be a bastardized turbo engine from 90 - 94? they were closed deck.

 

the part number on the ''header'' will tell us something. but what?

EDIT: i can't find the part number anywhere.

 

may have to go to legacycentral.org or ultimatesubaru.org to find a 1st gen legacy guy to help.

The na dual port header on first gens are one piece as well. This does kinda remind me of a turbo style header though

the svx eg33 has a similar style manifold, but of course it is a tri-port, for 6 cylinders.

Curious as to how your mid pipe looks like. Is it a J-Pipe?

not that i'm aware of.

the car is definitely a 96, ej22e, outback manual trans.

 

the exhaust is not original to the car. it looks as though the oil pan has been banged up. maybe the y-pipe was banged up as well.

 

from the pics, the engine / heads are dual port, no egr, this is consistent with the 96 outback ej22 manual trans.

 

the welds on the y-pipe looked a little rough? do you think they are factory welds?

 

i thionk this is an early 96 ej22 with 95 dual port heads, (i hear they flow better) built in the early days of the 96 model year. does it have a low serial number / vin? and the exhaust has been changed.

 

another possibility, the engine / heads were swapped.

 

there should be a vin etched into the block, passenger side bell housing. but it is hard to see with the engine in the car and hard to read the etched number even with the engine out of the car. so no real help.

 

7/95 build date was the very first month for the 96 MY.

 

so probably not a turbo short block, but a bit of an odd duck none the less.
