best way to do it is to get the "map" for the turbo you are looking at

I spent a lot of time researching this years ago, and eventually came to a really silly, easy conclusion.

When all done, look at target horsepower. Lets say whatever you are doing, you are after about 250 horsepower when done.

Find a stock car or diesel truck or something that makes 250 horsepower, and then look at its turbo map. Odds are, it will be REALLY good.

whether it is diesel, 4 stroke, 2 stroke, rpm, VE, whatever you want to look at, the horsepower really determines the size of the turbo.

From there some turbos are better at higher boost numbers then others, but most turbos have a surprising wide range of boost.
