Garrett DBB exchanged program will have that turbo good as new for 500$ plus shipping so long as the exhaust will is good and the bearings are good they will accept it
for the DBB program to work you must have 2 of the 3 parts usable
1 - turbine wheel
2- compressor wheel
3- bearing section itself.
i just had my old 3071R chra replaced under the DBB program due to a bearing housing cracking.
