so the trans from the 98 Foz could/would/should work, providing I
swap out the rear diff as well...A little digging tells me that the 98
Foz automatic is a 4.44 final - correct?
How would this affect fuel mileage/cruising RPMs in the Legacy?
guessing that RPMs would be little higher, resulting in slightly lower
fuel mileage... ?
the fozy trans is a 4.44 ratio.
and this will affect your fuel economy and ''power output''.
it will make your car ''quicker off the line''.
you can compensate for this by using the fozy wheels and tires. (and struts.)
the difference in ratio is almost the same as the difference in tire size.
but the larger tire size will mean you are driving faster than the speedo says, about 8% i think.
some have said it is not a noticeable difference, i don't know.
i'm just going from the math.
this speedo / odo error will also make it difficult to figure your true fuel economy.
but the error, what ever it is, will be consistent.
so once you learn what that is you can use that to adjust your speed and your MPG calculations.
and somewhere down the road, you could always swap in an outback instrument cluster and eliminate the error.
Previous owner mentioned that the "fuel tank" leaks if filled all the
way - is this more than likely the "filler neck rusting out because of
the plastic guard" problem?
usually it is the filler neck which is replaceable.
but there are some case of leaks on top of the tanks at the seams.
assuming the reports are correct.
WI, i guess you are in the rust belt?
if you remove the plastic cover, you will see the problem and likely locate the leak pretty quickly.
i repaired mine with JB Weld.
it worked great, but i sold the car a year later so i don't know how it is doing now.
but it was easier than replacing it and if it failed i could always replace it later.
and i shortened the cover so it was not underneath the filler neck.
