Contact these guys and ask for a shop that uses them for injector/injection pump/turbo repair work in your area.
http://www.westernturbo.com/about/index.htmlThey are an ADS member, a world wide organization dedicated to quality diesel component repair and are certified by companies like Bosch, ND, Garrett, and other manufacturers.
ADS members will not recommend dirt bags or second rate repair shops.
Some of the ADS members will replace your timing belt too, a LOST member near me found an ADS shop close to him that was happy to help him.
Best of Luck
