Right i finally found it.. but......... its 1GB of files
Subaru Impreza Manuals - 1993 to 2004 - various cars WRX, STi P1, etc
so i need to know what year you need. that way i can break it down to a 200-300mn file for you to download.
I will upload it and give you a link to download it from.
I know your is a 1.6L but im sure there is still alot of stuff you use in them too.
