idosubaru Posted October 23, 2007 Share Posted October 23, 2007 I'm installing an EJ22 in my 1997 Legacy LSi that had an EJ25 w/ EGR. i have an EJ22 that came out of a 1997 Impreza OBS, it doesn't have any of the lines for the charcoal canister evaporative emissions stuff, none of the metal lines are even there, the EGR stuff isn't there and the hole in the head isn't even tapped. Not sure why it doesn't have any of that, but what would happen if I install this intake in my originally EGR equipped Legacy? i'm curious, i might try it, but know that i'll have issues to deal with. will it at least run? were there any late 90's models without EGR, this came out of a 1997 Impreza OBS.

subaru360 Posted October 23, 2007 Share Posted October 23, 2007 It'll run. You will have a check engine light with an egr code. If you have access to the ecm out of the car you got the engine from, that might solve your check engine light if you install that ecm. As far as the canister lines go, I've done it the other way around. I put one that had the cansiter in place of one that didn't. I put the canister from the donor car in, so it really had 2 canisters, one in the back and one under the hood. Strangely no check engine light issues and everything worked normally.

idosubaru Posted October 23, 2007 Author Share Posted October 23, 2007 nah, don't have that car anymore, but i wish i did. strange thing i had 2 identical 1997 OBS (even the color). my daily driver has the EGR set up on it (unfortunately). and the other, exact same car, did not have any EGR stuff on it. bizarre, i wish i still had the vehicle to see what else was going on in the engine bay. i guess the question becomes, did any EJ OBDII vehicles not have EGR set ups, i could get a computer from one of those possibly...but i don't know of any that don't have it.

subaru360 Posted October 24, 2007 Share Posted October 24, 2007 Generally for the OBD2 cars 5 speeds didn't have EGR and automatics did. But there were some oddball ones that had the california, new york, maine etc emissions that were 5 speed with EGR. If you're putting the non EGR engine in an automatic, I don't think you will find an ecm for that setup, I don't think that was ever made. Link to comment Share on other sites More sharing options...
