I can say (again on a Stang, '93) That raising and lowering about one inch is about 10 miles a tank, or less or equal to than one mpg. The height advantage is because I live in the country and the AWD would make it more practical. Besides, I think it might help its looks a bit by giving it a more agressive stance. As far as the COG, I don't plan on winning at Watkins Glenn, so it should be fine if what I've seen of the suspension is any indication. It is my thought that some stiffer springs, struts, and swaybars will mor than make up for the height.
Maintenance has been done including a total fluid change through out. I didn't notice a limitted slip device in the rear diff. so maybe that would also be an upgrade for later.
The reason CAI's don't work well with some MAF's is because they tend to have a bend just before the sensor. The turbulence this causes keeps the MAF from getting a true reading, on most vehicles this causes a rich condition. It is eay to fix by assuring at least 5" of straight pipe in front of the sensor. I usually mod the harness for this, but this car might work without it.
I know quite a bit about cars so I'm not new to modding. I'm hust new to this type. I think this Legacy has allot of potential hiding in it, and I want to wake it up. The big problem is what fits. I see allot of parts for Imprezas, Outbacks, ect. but not so many for the Legacy. If these parts can be made to work on my car then I'll use them.
I will be taking it to 29 Palms this fall where there is allot of desert, heat, sand, and coyotes to shoot. If this car is up to hit I would like to make it the car I use there for hunting.
