how to build compressor wheel from x,y,z coordinates
how to build compressor wheel from x,y,z coordinates
(OP)
I have an opportunity to build a turbocharger compressor impellor/wheel. All I have at this time is some x,y,z, coordinates. Has anyone tried to build a complex solid before in solidworks? I need some helpful tips.

Using the xyz coords u should be able to create one blade of the wheel (using fit-spline appropriately) and circular pattern it. I wouldn't attempt to do it all using one feature.
Personally, I'd approach it this way:
1) Profile the side view (where the axis of rotation is along a SldWx axis).
2) Revolve that profile.
3) Obtain xyz cordinates for the space between the blades (relative to the axis of rotation)
4) Use the resulting surfaces (or body) to cut from the previously created revolve.
5) Circular pattern
6) Verify, verify, verify.
7) 3d print (rapid prototype)
8) Check the printed model
(I'm assuming this is for production)
In 7/10 of my applications I've found it simpler to cut away complex surfaces rather than to "extrude" them. Of course somebody with a better command of extruding features (lofts/ sweeps/ drafts) could argue the opposite. I'll let the experts speak.

Next use boundary surface.

Then a circular array around an axis and finally thicken.

Any suggestions for a faster approach? If you have built an impeller before. I am not sure that I have the information to complete the design on the hub. Also the center axis for rotation is something I came up with. Did I miss the information in the xyz coordinates for the axis rotation?

I think you should take a look at this http://www.ansys.com/products/blademodeler.asp
If you get the geometry wrong on the blades you will cause instability and bad airflow along with vibration.
