Need advice for my 93 Legacy sport.

[Liquidfreak117]

I am the new owner of a 93 Legacy sport. It was decently taken care of with no modifications at all. Bone sock with only 97000 miles on it. My question is about the coolant tank.one of the nikpples in the back and broke off. I want to replace it with something better than plastic. Could I use something from a WRX? Or something else on the aftermarket? Also, I have been reading about changinging my top half out for increased horespower without much investment. I am currently running the 2.2 turbo. This is my first Subaru. I want to do evrything as professional as possible because this is my daily driver. But, I love the idea of making it a nice sleeper in traffic or on the mountain. Any advice would be greatly appreciated.

The coolant reservoir can be replaced with one from a WRX, albeit w/ some fabrication.
