They have a 2.0 and a 2.5L if I remember right, I wouldn't go below the 2.5L in an Eagle.
I threw up a little bit in my mouth reading this post. The Subaru Forester 2.5L engine is a horrible engine. The '98 and early '99 motors blow their head gasket every 100K to 140K and immediately overheat, The late '99 to 2002 engines blow them too but don't immediately overheat and can limp along for awhile, and the newer engines are marginally better and still fragile. The CV shafts as an example are not even a third as strong as the Eagle equivalent. The under chassis has worst rust issues. The best part is that the stickshift '99 Subaru Forester with its puny little 2.5L gets worse gas mileage than a stickshift 1981 4.2L Eagle. (26 mpg versus 29). Ugh.
Then you go to drive the Subaru in the snow. What a useless death trap. The ABS is way too aggressive and it makes the car very dangerous to drive by itself and the all wheel drive traction is also pitiful compared to an Eagle. I'd rather drive a Spirit or Concord in the snow than a Subaru.
I've had several Subarus. Not bad cars IMO, even wheeled a bit with one and it was surprisingly good (Forester springs/structs modified to fit an Outback w00t). With a bit of clearnance and good tires they were surprisingly good in the snow, mud and woods. Rock crawling wasn't optimal though
I never had issues with their CV / driveshafts out on the trails, even hauled wood out at one point with the back loaded and a trailer full.
In 99 the Foresters received a "new" engine, the rest of the Subies were stuck with the old headgasket exploding head gaskets till 01. The newer ones leaked externally, Subaru's fix was putting in a type of sealant into it. Haven't looked at the newer engines though. There's a lot of Subies around with blown head gaskets that can be bought for a song, and it's a easy to do fix as well. Their heads didn't warp too fast or too much to boot, which was a bonus.
Rust eats all cars. Keep them undercoated. I live on the north east coast (Nova Scotia). Undercoating and a monthly wash keeps it at bay (except on Kias...holy sweet lord...)
