Default Turbo setup question

Im looking to build a turbo kit for my silverado. its a mainly stock 4.8 (yea i know) and found a steal of a deal on a turbo. These are the specs on it:
.50 A/R Compressor
.63 A/R Turbine
3" Inlet & 2" Outlet
Compressor Wheel 3" Exducer , 2" Inducer
Turbine Wheel 2.2" Exducer , 2.58" Inducer

Would this be a decent setup for my daily driver? I dont know what kind of boost or power range would work best. The guy says it starts spooling about 3K rpm. Input would be greatly appreciated.

IMHO, way to small for even a 4.8 That's only about a 56mm turbo. Probable good for about 350hp.

The guy told me is was good up to 400 HP. I've got a stock motor wit a ported and polished throttle body now. I was gonna try and find a ls6 cam and yellow springs and put me a small Turbo. The turbo has 1500 miles on it and zero shaft play and I can get it for 60 bucks! I figured I could get it and use it with my stock set up and upgrade when i do the cam swap.

I might be able to use that turbo on my sand rocket build. 0.6L, not 4.8L. You'll need a bigger turbo. Tell this guy its too small for your truck, but you know someone who is interested

Haha well its a heck of a.deal and even if I don't use it I think I could easily make my money back. I'm sure there's a ricer out there itching to try to boost his fart can tuner into the fast and the furious movie

That turbo would be hard to keep out of boost which would kill your mpg on your dd

What flange type? I would really think about selling it before using it, or better yer, get another one and you would be set.

I made 325 with a cam and just boltons with my 5.3. Your 4.8 wouldnt be far behind that.
