Hi all, i'm trying to figure out if any parts from the ej25 dohc engine will work on my wrx engine.
What i would like to know is if the following parts can be swapped over. Please list if you're speaking from experience or just speculating. My engine has some damage and there are plenty of 2.5's laying around!
thanks

Cam gears
front timing belt covers
idler pulleys
Water pump
Thermostate
thermostate housing

Cam gears i believe so
front timing belt covers yes
idler pulleys yes depends on year of engine
Water pump no use ej22t
Thermostate no use ej22t
thermostate housing no use ej22t
timing belt yes

Anyone know for sure what year 2.5 motor(s) would be compatable for my part list?
Thanks
Brent

1997-1998 DOHC EJ25 or 2002+ DOHC EJ20 for cam gears, timing belt covers, timing belt, and probably idler pulleys (maybe)
1991-1994 SOHC EJ22-T or 2002+ DOHC EJ20 for waterpump, thermostat, and thermostat housing
