turbo specs question

[Guest hgray14]

I saw this turbo for sale and am wondering what it means exactly. I have turbo books but I am looking for a quick and dirty answer on the stats of this turbo.

 

I know that 3" in and 2" out is good. My question is on the SPECS. I am going to be running an '82 turbo Z engine with NPR intercooler and improved fuel delivery, maybe even double injectors for each cylinder. If I can fit NO2 in there somewhere I might do that too. I am always struggling between whether I want my power from the starting line or whether I want a lot of high end power because I like to smoke people off the line but I also like to drive over 130mph. Anyway, what does .67 wheel trim, .70 A/R compressor and .63 A/R turbine tell me? Will this turbo be better for high end or low end power? Does this tell me whether it has a wide or narrow power band? Can a turbo like this really do 28 psi? That seems really high.

 

any help you can give me will be greatly appreciated.
