Hi guys, I'm new to this forum and would like some advice about the engine swap that will be getting done for my subaru pretty soon. I have a 2002 outback base 2.5l that I was pretty sure was a dohc when I first got it, and I havent checked the VIN yet to make sure since the car is at storage. Here is the question though, what would need to be done to make a DOHC work for a car that had a SOHC in it, because the engine is already on its way and it would cost way too much to send it back and get a new one. The engine I have coming is a 2005 ej254 DOHC 2.5l 16 valve with only about 65K miles on it, the engine block for my old engine is completely siezed up so replacing it is the only good option for me at this point, ill just scrap the old one or give it to someone who has the time to tinker with it. Any information would be very helpful , thanks.
