snowscooby Posted September 13, 2010 Share Posted September 13, 2010 I am looking at getting a ej25 dohc out of a 96 legacy and was curious if it would be a good pair for my heads from my 97 impreza 2.2l (its sohc). I don't know much about engine swaps, but am looking for a project and thought a franken motor would be a fun NA project. Quote Link to comment Share on other sites More sharing options...
Giraffe Attack Posted September 14, 2010 Share Posted September 14, 2010 (edited) A 2.5 block with 2.2 heads is a great start. I did a 2.5l SOHC '01 legacy block with 2.5l DOHC 97 legacy heads. worked out nicely. can give details if interested. if you need a hand, let me know.

LeoneTurbo Posted September 14, 2010 Share Posted September 14, 2010 Just make sure the block deck is 100% flat otherwise you will definately run into head gasket issues (a very common fault on non-turbo EJ25 blocks). Quote Link to comment Share on other sites More sharing options...

How does one check that (with a level?) and can it be machined flat again? So there shouldn't be a problem going from dohc to sohc? And I would like to hear more about your project!

LeoneTurbo Posted September 14, 2010 Share Posted September 14, 2010 Machining is no problem it can be done. Quote Link to comment Share on other sites More sharing options...
