Can anyone help me find the right turbo for this foreign car?

I have a old 2002 sm 520 Samsung. Yes. Samsung that makes phones makes cars and stuff. I'd like to see if it's even possible to find something or should I just take the car to a auto shop and ask for the right dimensions and all the calculations? My target is 300 hp I think that's realistic

You want an aftermarket turbo or replacement turbo?
