I just purchased a 93 Legacy 4WD wagon. The previous owner has replaced the original EJ22 long block with a SOHC EJ25 long block. He apears to have installed all the other pieces from the EJ22 but it won't run. It acts like it's out of cam timing. Does anyone know the differences between the two engines, if there is a different set up to the timing belt? He used the belt sprockets from theEJ22 on the EJ25.
