Hi,
I've got a 99 forester and its got a ej20 engine in it. I was wondering what other engines would fit into it, like a ej25 dohc or sohc or even something else and if so what is better?
EJ25 SOHC/DOHC NA's should fit in, as they came that way in the US. Neither makes significantly more power stock for stock. I prefer the SOHC because changing the timing belt is a breeze on it.
