My advise get the tranny number then go to jspec Subaru parts and get yourself a proper jdm swap, i have seen good deals and packages there, am waiting on a six speed that has both close ratio and long gears all in one for a fast road car. My 2c

It will physically bolt up just fine, but I'm fairly certain that 5th gear will be different. The Legacy Outbacks had a shorter (numerically higher) 5th gear to account for the taller tires they came with from the factory. The Outback Sport I'm pretty sure wouldn't have that.

If you can find the codes on your tranny and the replacement you're looking at, this table - http://www.gearhack.com/myink/ViewPa...ission%20Chart - will let you know what the gear ratios are. If I'm reading it right, I think the Outback Sport would fall under 5MT Push Clutch "US Impreza EJ22 MY99-01", in which case it also has the wrong final drive (3.90 vs your 4.11).

Ya I looked into it it is a different final drive, if I put it in anyway what would happen would I just have less power? Like less torque to the rpm

The front and rear diffs would be fighting each other since they would be trying to spin the wheels at different rates. The front wheels would rotate at a different rate than the rear wheels.
Eventually one of the diffs would fail because of this. Might fail in a week, might fail in a day, who knows except that it WOULD fail.

As Charlie said, the front and rear axles would be trying to spin different RPMs. Your free transmission would end up costing you lots of money to fix whatever part(s) of the drivetrain fail.
