Default turbo upgrade

Any input on a turbo upgrade? The buildup is moderate mods.. Looking for the 400-750 hp range eventually. Would like a turbo that can run with the 75hp injectors, but will really shine if I ever go to 140hp/ 90 hp injectors...

Answers in bold, saves 80 bucks right there. I don't even know what to recommend for a turbo to only get you to 400hp . But a 62mm is a well proven turbo.
