Impreza EJ20 SOHC to EJ25 DOHC Changeover

13 April 2017 - 08:34 PM

Hey guys

 

I got some overheating issues with my 03 Impreza GX. Planned on pulling the engine out and replacing head gaskets, etc.  Then I come across what I thought was another engine, overhauled around 40k ago.  I bought it, then I discover it's an EJ25 DOHC.

 

So, can I do the swap?  I'm thinking there's going to be some ECU issues, plus exhaust headers and maybe other stuff.  Anyone got some advice.

 

cheers
