Hi, I am fairly new on here and to Subaru ownership. I have made one post before I think looking for technical info and got a link to Impeza workshop manuals which were very good but I think I really need to start at the beginning. I have a Legacy estate, 2005 model 2.0 RE. So it's a nice big comfy car, full leather big sunroof, aircon, ,alloys etc. When it came to looking at the manuals one of the first questions engine wise was is it a single or double overhead cam, no idea. I know it's a 4 cylider 2 litre non turbo with 160 odd BHP but that's about it. Alos I've been reading about 4wd, I know it's a aymetrical system which I got the garage to explain but what's the power split? Does it have Torsen diffs, LSD, again no idea? Can anyone advis me or point me in the right direction, I'm not a numpy (honest) just haven't had a Subaru before. cheers in advance.
