Well I found about the best place in town. I decided to do the work myself - replacing glow plugs. Near the end of the job I saw that the turbo was damaged - the impeller was mangled. With a race coming the next weekend, I had to find a place. I found a rebuilt turbo shop in McDonough and they recommended 85 Automotive in Riverdale. The owner, Aaron, is great and he worked with me to keep the price reasonable. The work was A-1, and on time. Highly recommended. They are on GA-85, about 5-6 miles south of I-285, I-75 on the south side of town. It's hard to find, so call Aaron for directions. Number is 770-473-9094.
I have used Norcross Truck and Auto before. They are Low-Tech. I had a problem last year that took them too long to figure out because they have no diag computers. It took a week to get back but they charged me a reasonable fee. I have had good luck with them in the past tho...
Thanks for the help!!!
