I just bought another engine for my 99 9-5 to replace one that has seen its better day. The replacement has 118,000 miles and looks to have been shipped with a newer turbo on it. My other motor has about 40,000 miles on the replacement turbo that I know for a fact. Is there any way to determine the production year of my replacement motor's turbo since that one is already on the manifold? Or should I just swap mine over and save the other for parts?
