I have a 1994 Legacy Wagon (N/A), I'm wondering what other models&years I can use to retrofit parts from. Things like Suspension, body panels, interior, brakes, wheels, lights, etc. Would love to hear some opinions about upgrades, etc. I'm new to the Subaru world, just came from the world of BMW e30 so everything is quite different. Thanks in advance!

What are you looking to know?  You can make a lot of stuff fit, depending on how determined you are. The search feature will help if you want specifics.  Look around the Repair Manual section, check out some of the build threads people have. Should get some ideas flowing.  If you can imagine it, chances are, someone around here has at least thought about it, if not tried it.  If not, they give some great input, and I look forward to the build thread.

 

Also, welcome!
