I do believe the timing belt is found on just about all the subaru models. The 3.0 probably has a chain becuase of the bigger engine (though they could've used a bigger, stronger belt I suppose).

From cars101.com: http://www.cars101.com/subaru/outback/outback2003.html

* 3.0L DOHC H-6 cylinder engine.

This engine has an aluminum crankcase, double-overhead camshafts (dohc) chain-driven with four valves per cylinder. The timing chain does NOT have a replacement schedule - suggested replacement of the rubber belt on the 2.5L 4 cyl is 105,000 miles.
The 6 cylinder uses Direct Ignition with an individual ignition coil for each cylinder so there is no distributor or sparkplug wires.
The H6-3.0 produces nearly 30 percent more horsepower and torque than the 165-horsepower 2.5-liter H-4 and is only 0.8 inches longer. Premium fuel, 91 octane, is recommended.

o 212 horsepower @ 6,000 rpm
o 210 lb.-ft. of peak torque @ 4,400 rpm

174 lb.-ft of torque @ 2,200 rpm

Yes the posts are correct, the 3.0 H6 in the Legacy is chain driven. It was done that way because there wasn't enough room in the current Legacy body at the time to fit a 6 cylinder and a timing belt. The chain cover is skinny compared to the tbelt cover.

Now the SVX on the other hand is a belt driven H6. But that is a story for a different time and thread!
