I've been searching for some thoughts on this and not much is coming up. I have a cpt61bb (turbonetics tag on compressor housing says 11356-bb), and overall I'm happy with it. Only thing is there is a small amount of play in the shaft, and I am getting some oil into the exhaust side. It's minimal right now, but that's not permanent I'm sure. Is it feasible to have this one rebuilt? On average, what does it cost for a ball bearing turbo like this? I never have found a whole lot of information on it, although it is more than adequate for what I'm doing. I don't need the absolute latest, most cutting edge turbo, This car will most likely never see the low side of 11.0 anyways, at least not for a few years. If it isn't reasonable to get this one rebuilt it can be replaced, but that seems like a waste from my limited knowledge perspective.
