Hope someone may know this..... I have a 2.2L from a 1995 Legacy with manual transmission......will it work in my 96 Legacy 2.2L with auto transmission? In other words, can I use the intake, ECU, and emissions on 96 to work and pass inspection? Is there an outlet on 95 block that can be used to work 96 emissions? The motor is in and working in car, but now I have to fix emissions to pass inspection...I know stupid me?

the 95 Legacy MT doesn't have an EGR valve and there's no easy work around for it.

If you saved your 96 Intake manifold you *might* be able to tap into the exhaust pipe to get the EGR pipes refitted to your non-EGR engine.

In other words - tap into the exhaust - attach EGR pipes - which attach to your 1996 Intake manifold - which bolts right up and plugs right in (just like it used to).

But it's going to take some custom pipe work (not that big of a deal with the right tools and equipment - simple actually - but troublesome for most at home mechanics).

Good luck this is just one daunting issue to deal with.

I think you're saying retained the automatic? If you had the manual trans then you can get around it, but not with the auto.

Thanx for the reply. I have the 96 intake and all the emissions hoses and such. My problem is the EGR pipe that is suppose to connect to the LH cylinder back to EGR valve to recirulate. BTW I don't have the 96 block. There appears to be a plug on the 95 LH cylinder...is that where the EGR pipe connects? or should the connection be on the exhaust manifold itself ?

The EGR pipe has a pipe fitting on the end that threads into the back of the drivers side head - that plug you refer too no doubt. it's probably theoretically possible to drill and tap that area for the pipe, though I've never heard of anyone doing that.

i doubt it's just a plug, it's probably a boss - an area intended to be drilled and tapped for those engines requiring EGR. in other words the foundry doesn't make "EGR heads" and "Non EGR heads" - they just make one head which gets machined appropriately after the foundry creates them. so yes - the heads are identical and one can be "turned into" another.

my guess is it's drilling and tapping though, not just removing a plug. i've never seen any with just a plug, it's always been untouched metal. but if youre lucky and have a plug - post a picture that would be awesome.

http://www.ultimatesubaru.org/forum/[IMG]http://i809.photobucket.com/albums/zz12/zzguy46/1995Subaru/95004.jpg[/IMG]OK give it a try, pictures on photobucket, showing where I think the EGR pipe connects next to EGR port, and the plug near LH cylinder head where I think it might connect.

no i think that plug you're looking at is the coolant passage drain plug.

the EGR pipe fits on the rear of the engine, not the bottom of the engine where you're taking pictures. like i said - there should not be a plug there, it's not going to be that easy unless you're really lucky.

Thanx. Dang...wish I could just see what EGR pipe looks like on the engine.

I found part.http://www.ultimatesubaru.org/forum/[IMG]http://i809.photobucket.com/albums/zz12/zzguy46/1995Subaru/PIPE3.jpg[/IMG]

Yep, that's it the bottom threaded part threads into the rear of the head like i mentioned above.

If you have the old intake like you said - you should be able to look at that pipe right? Or do you not have that pipe any more?

If you still have the old engine you could theoretically swap heads on that one side to install a head with an EGR port.

You could possibly drill/tap it out with a right angle drill or right angle drill attachment. I've used those before to do drilling/tapping on the front of the engine, so it can e done on the rear too. Be nice to have an EGR equipped head to look at though and get right.

Otherwise looks like there should be plenty of room to work with back there.

Thanx you are being so helpful. No I don't have old block, too bad had blown headgasket....the other side...go figure. So no...I don't have the pipe. The old intake is all in pieces too, so I got to put it back together. I'm thinking about a new direction, getting a 96 swap motor and selling this 95. Its a great engine, and I had it all fixed up, waterpump, T-belt and more. Hate to give up what I know is good for the unknown.
