moosebs09 Posted September 12, 2005 Share Posted September 12, 2005 I have a 1996 Legacy Lsi that might need some engine work and instead of putting too much work into it I would rather buy a new engine with less miles on it. If anyone knows about fits as far as a 2.2 L for this car or what size engine I should be looking for to mount up without any modifaction really needed please let me know. I realize is it a 2.5 L engine and I was just wondering if the 2.2L would fit and from what years/models I might be able to find a match as far as the engine. Also I found a set of heads, which is what I need but these heads are off a 2.5 L from a 99 legacy outback wagon, Any idea if these fit on my engine? Im new to subarus so I am learning about all this in the process so any help would be greatly appreciated. Thank you. Link to comment Share on other sites More sharing options...

low_suby_wagon Posted September 12, 2005 Share Posted September 12, 2005 Doing a 2.5 head on 2.2 block is what us old schooler leg owners call a frankenstien. I have never personally did it, but I know people who have. This can make your leg very fast. Especially when you use a GT computer and throttle body. Why don't you go all the way with a JDM H25 conversion? Link to comment Share on other sites More sharing options...
moosebs09 Posted September 12, 2005 Author Share Posted September 12, 2005 No im not using a 2.5 on a 2.2. I currently have a 2.5 and might replace the head on that with a 2.5 head, I was just wondering about the fit of the 2.2 L in a legacy LSi in case that is the cheapest way for me to go right now as far as an engine. This isnt going to be a big project yet, I will do that later on, for now I want to get it back on the road and running the easiest and cheapest way possible.

low_suby_wagon Posted September 12, 2005 Share Posted September 12, 2005 Oh, OK well it wont matter if its 2.5 or 2.5rs gt or not it will fit. Is the heads warped? maybe you can have them machined at a local shop. I have seen alot of heads for sale on ebay cheap. Link to comment Share on other sites More sharing options...
Yukonart Posted September 21, 2005 Share Posted September 21, 2005 Doing a 2.5 head on 2.2 block is what us old schooler leg owners call a frankenstien.

Why don't you go all the way with a JDM H25 conversion?  What?!?!?!?!? An "oldschooler" leg owner would know that the engine codes are EJ20, EJ22, EJ25, etc. . . . and it's NOT, I repeat NOT possible to make a naturally aspirated Legacy fast. This is why Subaru made, and again makes, turbo models. Link to comment Share on other sites More sharing options...
nathaniel_h2o Posted November 8, 2011 Share Posted November 8, 2011 ive seen someone make 300hp and a ej25d. even with no turbo. but thats the only one ive ever seen. the ej25d or ej22 that comes in the legacy are great economy motors. hard to make good power without lots of money to build them. im planning on building a 25d with ej22 heads, the whole port polish works and thinking about making some custom ITB's (indevidual throttle bodies) making four of them work will be hard. but if i could get 220 out of a ej25d, than i would be happy Link to comment Share on other sites More sharing options...

BAC5.2 Posted November 8, 2011 Share Posted November 8, 2011 Building a high output N/A Subaru engine is a waste of time and money.
