Main reasons for switching to the 4Runner:
- Subaru gas mileage wasn't great (see above)
- Lack of a locking front or rear diff, and poor articulation (even without anti-sway bars) means that you get diagonal wheel spin quite easily
- My Forester, and others of the same era, have undersized radiators, so it overheats when climbing a steep dirt road in the summer. Add a turbo and it gets worse, because Subaru doesn't upsize the rad for the turbo model...
- no easy way to protect the vulnerable auto trans pan (and the 5-speed manual just doesn't work offroad, unless you are only interested in smooth dirt roads)
>> keep in mind that I have heavily modified the front and rear bumpers to improve clearance. Combine this with the locking center clutch pack mod and the lift, and the Forester is quite good on moderate offroad trails, until a tire lifts in the air.
I don't want to mislead people, this car has been great for getting me offroad without using a motorcycle. In the car, I went slower, and enjoyed the same areas I had taken my motorcycle, but or course at a much slower pace. This was great, since the lower speeds helped me to appreciate new things. And I liked being able to plenty of carry camping gear so I can camp wherever, and enjoy the solitude.
The stock 4runner has similar ground clearance to my modified Forester (measured from the lowest point), has a little more space, but it has way more articulation AND the locking rear diff. The gas mileage so far is about the same around town, and ~15% lower on the freeway. It will get worse once I add some A/T tires, but it is still quite close while providing a lot more capability.
YMMV
