Blown turbo cause of bad motor? WTF Now?

[howslowcanyougo]

SBR said they'd rebuid it for for $400.00, I'm selling it for $500.00 to 4X4 and I bought Tom's FP T28 for my 2G A/T. I have yet find anything wrong with my motor that would have affected the blown turbo as SBR described?

I guess I can say that given that the turbo is almost $1100.00 new, that SBR "met me in the middle" and compromised by charging me $400.00 for a complete rebuild.
