August 1, 201015 yr SO... am I right to conclude that if an car came with EGR, it has those litle fun holes poked here and there for the EGR system. As for example those metal lines that run to the throttle? And when you swap in an non-egr system, what do you do with these possible vacumn leaks? Clog them up or what? :| From EJ25D 1996' to a 1995 EJ22!
August 1, 201015 yr You're talking about swapping in a non EGR engine, right? Once you put in the new engine, thats it. No extra hoses or parts, just a CEL that you'll never get rid of. Unless you are re-using the throttle body, than there's gonna be a few extra hoses to plug up... Edited August 1, 201015 yr by outbackusjunkus
August 3, 201015 yr you are removing an EGR engine...and all it's "holes/vacuums" you mention with it. then you install a non-EGR engine without any "holes..etc" so you have nothing to do. you'll have a check engine light that is very difficult to get rid of (no one has successfully done it yet). i currently have one and have cut wires, swapped ECU's...etc and there's something funny about how Subaru did this and no one's figured it out yet. my state doesn't require emissions or anything so it doesn't matter.

Wonder why the ECU swap didn't work. Did you still have the EGR solinoid wired up when you did? I did some more searching on this and I guess the computer switches the solenoid, then looks for changes in the O2 sensor reading to make sure the system is working. I think the non EGR ECU swap will be the only way to get rid of these codes, and w/all EGR wires cut so it doesn't start "looking" for something it thinks should be there. Thread Hijack...accomplished.
August 4, 201015 yr Swap the intake manifold from the original engine and drill and tap the cylinder head for the egr pipe to go into.
August 4, 201015 yr Swap the intake manifold from the original engine and drill and tap the cylinder head for the egr pipe to go into. he's talking about doing a 2.5 to 2.2 swap. Intakes don't interchange.
August 4, 201015 yr SO... am I right to conclude that if an car came with EGR, it has those litle fun holes poked here and there for the EGR system. As for example those metal lines that run to the throttle? Little metal lines to throttle? I think you are confusing the small coolant hoses that run to the throttle base for vac hose. they are coolant lines, and the 2.2 will have them as well.
August 4, 201015 yr he's talking about doing a 2.5 to 2.2 swap. Intakes don't interchange. No but every item on the 2.5 intake can be moved over to a 2.2 intake if you use a 95, 96 or 97 EGR intake manifold. Thats TBI, piping, sensors, the whole thing. NO CEL's the last 3 I did.

August 4, 201015 yr I got rid of the check engine light related to the EGR. its pretty easy. 1. use the wiring harness with the red plug for the egr "pressure valve monitor?" thats located under the drivers side of the manifold. 2. take the whole egr set up off a 2.2 or 2.5 engine ( egr valve, pressure monitor, vacume thingy and throttle body) 3.connect all hoses/vacume lines as if you had an egr. the ecu is just looking at the pressure monitor so it has no idea that the EGR isn't hooked up to the exhaust. The egr valve will open and close like its supposed to... I drove my OBW for a month like this until I got a manifold with EGR...I
August 4, 201015 yr This is what I mean guys..... just plug them if you are willing to live with the CEL.

I'm going to reconnect it so eh, I'm not taping the block/manifold though.
August 5, 201015 yr If you're using a 95 intake, you shouldn't need to swap TBs. (same TPS as the 25) Just plug the EGR solenoid in electrically......leave all the rest of the EGR stuff off.
