turbine outlet diameter

just wondering if someone could tell me the diameter of the turbine outlet (where the downpipe connects to the turbo)? Also if you know, could you tell me the size of the wastegate outlet as well. Thanks in advance........

Also the diameter of the intake manifold would be nice to know as well. Just for some general info, i tried a search but didn't get anything useful.

NorCal,
I'm picking up a used stock turbo later this afternoon. I'll post up the measurements later today.

okay the wastegate door is ~1-1/4" (I'm guessing the wastegate itelf is about 1"). The turbine outlet tapers to just a little less than 2" so the turbine itself is smaller. I can get better measurements with calipers when I disassemble it later this week.
