rebuild turbo.. use on sr20?

[2501]

My friend pretty much gave me a turbo he'd bough off of some other guy for his b16. He needed to make a car payment, so I paid for 4 new alpines, and a turbo. Easy $100 trade. Anyway I have a garrett t3 a/r .42 .68 turbo sitting in my basement that I'm looking at rebuilding, but instead of selling it, would it be any use on an sr20? I'm just wondering. Hell, I dont even have a 240 yet, but I'm just wondering if I rebuild it and hold onto the thing, if it would come in any use, or I should sell it and sit on the money.

Open to suggestions, I'm an armchair theorist when it comes to 90% of drift tech.
