2.7L TT @ conditions :
22 PSI ( nice target PSI )
4000 RPM ( youd want to make full boost by then )
110 deg F intake temp ( ok iat )
what do you guys come up with.. Ill compare it to my notes..
Im trying to match a turbo.
Looks like the GT22 would be most up to this task.

Taking your question literally ~32lbs of air per minute/~420cfm for 2.7l@22#@4000rpm.
This info really won't help you at all in sizing the turbo properly. You're going to have to do calculations for many points on the compressor map to find out if you're anywhere near the ballpark.
Hint: In our cars a GT22 will fall flat on its face well before a K04.16 will.
Edit: Redid my calculations taking ambient temperature into account, knew I forgot something, not much of a diff though
