Outer Limits 4x4 Board

Ok i have a td42, going into a gu it is fully rebiult, ballanced, blue printed, 3 way coated pistons and ported head. Its built to alot higher spec's then i needed to, but figured while its apart and i have the time nd spare coin id take it abit futher incase it ever see's dirt (tow car).

So same idea with the turbo would like it to be capable of 30psi stable if i ever take it up there. Will this turbo allow for this?
Specifications:
Water & Oil-cooled,
External wastegated.
Compressor Cover 0.5A/R
Compressor Cover inlet: 2.5"
Compressor Cover outlet 2"
Compressor Trim: 48
Inducer 53mm, exducer 76.5mm
Exhaust side:
T3 size flange.
0.58AR turbine housing.
Turbine wheel Exducer 48mm, Inducer 64.5mm

Any one. Come on i know theres some gurus out there?

Need to see the comp flow map to determine where its at efficiency wise at 30psi.
Apart from that it shouldnt have any problems making 30psi. But by the looks of the wheel sizes it will be a little lazy to come onto boost.
