Obvious con of a ceramic turbo: The ceramic turbine wheel will shatter under high RPM use.

what the hell are you talkin about? he's asking about ball bearings

Ceramic ball bearing turbo: Turbo with ball bearings and a ceramic turbine wheel. Correct me if I'm wrong.

Re: stainless steel ball bearing or ceramic ball bearing? (beepy)
from the turbonetics website about their ceramic ball bearings:
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by turbonetics »</TD></TR><TR><TD CLASS="quote">Q: Why do Turbonetics ceramic ball-bearing turbos only use one ball bearing?
A: Turbonetics created the ceramic ball bearing turbocharger for durability. By utilizing a single, ceramic, angular-contact ball bearing on the compressor side instead of the more common bronze piece, the ball bearing can absorb the thrust loading that all too often can lead to turbo failure in high performance gas applications. The Turbonetics ceramic ball bearing turbo can withstand up to 50 times the thrust load capacity, compared to a conventional floating bearing unit.
*Dual ball bearing turbos can only withstand 2-3 times more thrust loading than standard turbos.
Q: What is on the turbine side of the turbocharger in the ceramic ball-bearing turbochargers?
A: The turbine side of the ceramic ball-bearing turbo uses a floating bearing to dampen the harmonics and vibrations that are transmitted through the turbocharger. This allows Turbonetics to balance the turbo to the most demanding tolerances.

Don't know how helpful that was, but I haven't heard anything reliability wise that would make me want to choose the turbonetics bearing setup over the garrett dual bb.

Re: stainless steel ball bearing or ceramic ball bearing? (hpfsi)
keep in mind that most all ceramic ball bearing cartridges only use the ceramic ball bearing on the compressor section, while still using the journal/bushing bearing on the turbine section...
while the stainless steel ballbearing Garrett GT cartridges utilize the ballbearing on both the compressor and turbine sections.
also, the stainless ball bearing can handle a much higher thrust load than the ceramic ball bearing.
i can say this, in the 4 years that we have been offering the GT stainless ballbearing cartridges, we have only seen one come back....
and it was because the customer "wanted to see how it worked" and improperly disassembled the cartridge...
