Cheap Ebay GT-45 upgrades? possible?

Actually i read through MAD DART's thread and I did not see were he opened up and checked the GT 45's unless I missed a page.Mad Dart went to the trouble to check other components I wonder why he didn't check the Turbo's???
I hate to take mine apart and ruin it but it sure looks reasonable with the propper tools
I AM CURIOUS AS TO WHAT GRADE BEARINGS THEY ARE USING? THEY MIGHT EASILY BE UPGRADEABLE.
I rebuild HIGH speed spindles for machine tools as a function of my business so I Know bearings and can get them for 50% off list.
IF ANYBODY HAS PULLED ONE APART THEY COULD SAVE ME SOME TROUBLE IF THEY COULD GIVE ME A HEADS UP AS TO WHAT THE BEARINGS ARE IN GT-45

FOR $260 FOR THE WHOLE UNIT THE BEARINGS HAVE TO BE SOMEWHAT INFERIOR!!!

All I did was run 6 quarts of oil out the Drains on mine, There are no debris in these turbo's. Most of that BS is coming from guys that have not used them. People BEAT on these Turbo's with Diesel Trucks to 55PSI and More with over 40K miles on them. In my opinion and all the research I have read they are pretty much bullet proof. There are sellers on theturboforums.com that SWEAR they are indestructible, heavier than they would like but very strong and stout.

There are Rebuild kits on Ebay as well but I have not heard of anyone needing one as of yet.
