The actuator will prob be a -31 - u cant really tell by looking.

There is no need to change the actuator for the sake of it - it appeard to be doing it's job. As for the cam, it depends on the turbo u have. You say hybrid, but that could mean anything. If it's a 0.36 exhasut housing, i'd put a CVH 35 Kent cam in, they work very well. If it's a 0.48 housing, then either a new std one, or the Piper 285T.
