I would run a compression and leak down test before putting a turbo on it. And again, STAY AWAY FROM EBAY. If you want to turbo your car get a decent turbo. As far as trim and everything I haven't done my research so I have no input on that. But you'll need: oil lines, engine management, fuel pump, fuel injectors ect. Just spend some time online looking at other peoples turbo build and learn a couple things and good luck.
