Opinions Please
 

2000 A-6 2.7T 196,000 miles
Would like your opinions and /or suggestions please.
This vehicle needs 2 new turbos and mechanic feels probably not worth doing due to high mileage unless I also have the engine rebuilt at same time as the new turbos would stress the engine that already has high miles. He feels replacing only the turbos would be a waste of money.
What say you all?
Do I need to rebuild engine when replacing the turbos?
Thank you in advance,
Kurt

go buy a new/used audi
