it probably can't support 22psi (odd number)
can yuou provide any more information? the turbine A/R? can you measure the compressor wheel's inducer and exducer?
from my little bit of research, saab used the 55 trim compressor wheel:
you can see the max the compressor can flow is 20 lb/min, which is equilvant to 190-200BHP. (20 x 11.5 x .00916)
the max psi is can run at is 2.075PR or 16psi (2.075 X 14.7 - 14.7)

I made 200rwhp at 13psi on a .48/.49 with a **** tune, so the turbo will easily do 220-230 on 13psi. If you intend to reliably rev to 8500rpm, you're going to need valve springs, rods, and oil pump gears.

then a gt28 is the deal unless you want to convert to all mitsubishi then a 16g would do it as well.
the chart looks pretty good it has the head room and good effeciency
