Turbonetics is the cheapest at about $900 each for a standard bearing unit.

I do have a pair of Turbonetics 60-1 HI-FI turbos with To4b covers, P-trim shafts, and .68 A/R on center housings I will be selling shortly. They started spooling about 2500 rpm on my 347". One is fresh with new bearings and seal, the other needs a turbine shaft, it is scored from a bad bearing. A shaft is about $150 for a new one, or can be repaired for about $75.
I went to a larger full ball bearing set, that's why I did not repair and reuse. I made 751 RWHP on 93 octane at 6100 rpm at only 14 psi.

Awesome turbos for the price! ;)

pm me when you do sell, i need two pairs, one for my buddys project, and one for my malibu

I should have them for sale in January sometime. I am not to sure what they are worth, you would have to throw me an offer. :)
