Generally yes you can use a NA cam in a turbo motor, however depending on spec it'll more than likly have a hell of alot more overlap than a turbo spec cam. For certian situations this is not clever but it can be dialled out within the conifines of the valve train assembly and piston valve cutouts.
From what ive seen most cossie builds like a fairly low duration(260 ish) with 9mm lift(ish).
A "mild" NA cam could have the same 260 duration but would more than likly have something closer to 11mm lift.....possibly bordering on overly steep ramp angles which maybe force you into solid lifter territory.
Other end of the scale would be knocking onto 280-290 duration and 13.5+ lift....defo solids and too much overlap to dial out really so in effect NA only

All of the above is just part of my understanding of it, cam specs/choice go alot deeper and really should be spec'd to the specific build rather than using a general grind if you like.
