Turbo sizing

I know this question is probably asked 100 times a week but I have tried to read compressor maps and I just cant do it. So I am going to list my setup and hopefully someone will chime in with some expert knowledge of what turbo I will need. I will like to try and keep the car on pump gas and decent street ability since it is a street car. Any help will be appreciated. Also, if the turbo I have is right then what kind of HP do you guys think it will be putting out with my current setup. Just trying to get an idea of what I can make with a tune or do I need to change turbos before sending the money on a tune. Again, thanks for any help.
