LegacyRS Posted October 6, 2004 Share Posted October 6, 2004 I asked this in the N/A forum, but maybe it belongs here. So the deal is, I have a '94 Legacy Brighton Wagon with the EJ22. A friend of mine is swapping the EJ25 from his RS for a EJ257. He has offered me his EJ25. Is the engine swap from the EJ22 to the EJ25 feasable? Im a subaru Newbie, but as old school a car guy, as any 21 yearold can be. Thanks a ton for info! My apologies if this has been covered a million times before.

evolutionmovement Posted October 6, 2004 Share Posted October 6, 2004 Yes. I wouldn't bother if it's a phase I (DOHC), but a phase II would be fine. The extra torque should be pretty noticeable in the older car. The engine will drop right in, but the problem is going to be wiring - especially as the old engine is OBD I and the new one is OBD II. If you're using a phase II engine, it may be as simple a fix as swapping your old engine's top end on the EJ25 bottom and running it off the stock computer, but I'm not sure if there'd be driveability issues or not.

rao Posted October 6, 2004 Share Posted October 6, 2004 You cn find all of the info you need here: [url]http://forums.nasioc.com/forums/forumdisplay.php?f=87[/url] It is about as basic a swap as you can do. As noted above, the wiring is the only ttircky part. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
LegacyRS Posted October 6, 2004 Author Share Posted October 6, 2004 Thanks a ton for the replys. all my questions have been answered. The ngine is almost new. Its from a 2002 2.5 RS. It has less than 20,000km on it. The engine was replaced under warranty in the 2.5RS about 7 months ago due to a cracked block. Link to comment Share on other sites More sharing options...
subiekid Posted October 7, 2004 Share Posted October 7, 2004 i have a question. Is your car this body style? [url]http://myweb.cableone.net/subiekid/[/url] Just wondering because I did not know that Subaru made the brighton in the Legacy untill the BG.

LegacyRS Posted October 7, 2004 Author Share Posted October 7, 2004 Yes it is that body style. I might be crazy (I am a recent Subie convert), but am pretty sure its just a brighton. When Im done, I hope its a whole lot more than the body suggests. With the engine swap, I will do the suspension as well. Springs, shocks, shock tower braces, urethane bushings, larger anti roll bars. Just enough to make the chassis much faster than the engine. I think I will just put a set of wheels from a 2.5RS on it for a while, then gets oem nicer wheels as the car takes shape over the next year or so.

LegacyRS Posted October 7, 2004 Author Share Posted October 7, 2004 /\--Out of curiosity, could you do this swap as easily into the even older Legacy body style? Link to comment Share on other sites More sharing options...
evolutionmovement Posted October 7, 2004 Share Posted October 7, 2004 The older style is what I was thinking you had. Yes, it will swap in as easily - they are very near the same car rebodied. Steve Link to comment Share on other sites More sharing options...
LegacyRS Posted October 8, 2004 Author Share Posted October 8, 2004 So how complicated are the electrical issues I am going to face? Should I (or do I ahve to) relace the ECU, and all those bits? Link to comment Share on other sites More sharing options...
evolutionmovement Posted October 8, 2004 Share Posted October 8, 2004 For the SOHC engine, you SHOULD (but this is an educated guess) be able to swap the EJ22 top end and sensors over and run stock ECU. As for the DOHC and maybe some other better info ...
