I am a little confused. Maybe it's because I am using a Chilton's manual. My 1993 Impreza has labels under the hood saying the motor is a 1.8 liter engine (EJ18). I am working on the timing belt section. It has just one long 211 tooth timing belt. Chiltons manual shows the 1.8 engine with two belts and the 2.2 looks just like my motor with one belt. Is the manual wrong, or is it possible somebody put another engine in?
