Default Final Drive ratio & 6th gear ratio?

Does anyone know what the final drive ratio and 6th gear ratio
is on the STi 6-speed

also what kind of power is it rated for? anyone have any problems
with stripping gears at all with this gearbox?

I was looking at a gearset swap for my 5MT, but the final drive
ratios and the 5th gear ratio kind of shyed me away from it, I
don't fancy a set that's overly loud (daily driver) or one that can
only get as low as 4000rpm in 5th doing 70 on the highway.

no reason really, it's just a preference. I want a strong gearbox
that can do better than 350-380 to even 400hp/tq.

all of this would be going in a 2000 Impreza 2.5RS, so I'd need
the conversion kit, and the transmission, at most the swap (priced
from rallispec) will run about $9300.. which is kind of disappointing..

edit: and I take a second look at the rallispec page and find my
exact answer. Gah i'm blind! 6th is 0.842 with a FD of 3.900
which puts me at 2270rpm doing 70 on the highway..

anyone know of my alternatives? 10 grand is almost the cost
of the entire car.. Rallispec also has a 5MT STi RA meshbox gearset.

anyone know what the stock FD ratio is for the 2000 Impreza 2.5RS 5MT ? Oh and edit-edit, anyone have experience with this
gearset as well? for $1400 it doesn't sound bad, I hear the Kaaz
whines like a supercharger.

I might just get the STi RA gearset... mucho cheaper
