Impreza's have the EJ18 (1.8) for 93 and 94, the EJ22 didn't go into them until 95, so for 95 and 96 you could only get the EJ22 in an Impreza LX with an automatic, the 96 Outback Sport didn't even have the 2.2. In 97, only automatic Impreza's had the 2.2. In 98, Subaru dropped the 1.8, leaving the EJ22 for all Impreza's, and in 99-01 came the 2.5RS which had the EJ25.
