Turbocharger Compressor Characteristics. Answered

I am working on building a micro jet engine, and I have to select between the following compressor wheels  http://www.ebay.com/itm/Turbo-charger-Compressor-Wheel-H1C-H1E-3599644-Ind-56-00mm-Exd-83-00mm/262249425295?_trksid=p2047675.c100623.m-1&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D40130%26meid%3Da741d83f102946f8ab1a494b9f98692c%26pid%3D100623%26rk%3D4%26rkt%3D6%26sd%3D301844324395 or http://www.ebay.com/itm/HE351CW-HE431V-HX40W-HY35-Turbo-Turbocharger-Compressor-Wheel-4035879/111866311491?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D20131003132420%26meid%3D42565bcbcf264701aa897ff600931d8c%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D301844324395. However the seller does not seem to have any data regarding the wheels max RPM, slip factor, blade angle, and pressure gain at different RPM's ( probably a graph ). Is there any way I can get these piece of information about the wheels especially the first three. Most of the wheel parameters like the gas tangential velocity, radial velocity and the mass flow rate at the wheel's outlet need these values to calculate.
Thanks for any help.

And you hope we may have the info you need.

See a titanium 60,000 RPM 12,000 PSI steam Turbine wheel used to drive a bus load of people up and down SF streets and a canary could breath the exhaust..
