Hello everyone, new subaru owner over here. I picked up a 1997 Legacy Outback for $300 from a buddy of mine. The car is in great shape cosmetically; especially since it has 174k miles on it. It came stock with a 2.5l that apparently developed a problem, so the car lot he bought it from swapped in a 2.2l. He says it hasn't ran right since; hence the reason he sold it. My buddy is a great guy, but doesn't seem to be working with a few deck and I believe he got himself ripped off. The car turns over and runs, but the power steering leaks and the car seems to hesitate during takeoff. I haven't checked/changed any fluids yet though. Since I'm new and all, I was hoping some of the more experienced folks out there would let me in on tips and tricks, performance modifications or basically any information you're willing to share. A good place to start is by determining if the engine I have is indeed a 2.2. How could I find that out? Thanks in advance!
