You two are saying the same thing.
I think he said that soldering the wires has no effect on bearing failure.
Maybe you are saying that intermittent connections could cause surging?

So are the bearing failures on Auto's only?

Ok?

I think I will wait for GM to give some kind of reason. I would think the surge form -15 PSI to 23 PSI back to -20.3 PSI would be as much a issue if not more.

You may be right but I need to see something more detailed on this before I will bite on anything more than just a bad bearing. I will wait to see what else comes up.

Too few to tell if this means anything at this point. Also there are more Auto SS than 5 sp.

Update - They will know more on the Turbo availability this Friday. I'll pose some questions, when I call on status Friday, in regards to what they believe the bearing failures are from.

Thanks it would be good to hear their take on it.

Is it a product of China or Japan? Any idea on the original manufacturer?

It is a Bosch turbo, so I would think it would be coming from Germany...

It is Honeywell Turbo Technologies who make the turbo if I recall. I never head of a Bosch.

They are the company that makes most factory turbochargers. Note they are also Garrett Turbos but that name is now only used on non OE applications. They are based Morges, Switzerland.

They are made in Brazil, Mexico, China, Japan, South Korea, Austrailia, Czech Repub, France, Irerland, England and Romainia. Not sure where the GM one is made.

Our little unit is not some generic off brand unit. It is made buy one of the best suppliers around for OE applications as well as industry and racing. When you think Honeywell think Garrett.

Now Bosch contributes many electrical parts for the turbo system. My new Map sensors are Bosch in the stage kit.
