    What diesel motor is in a '91 3500?
    Is it a turbo and if not what year did they start putting a turbo in?

    Thanks for your help in advance.

    91 is most likely a 6.2NA with a 4L80E. You could order a factory Banks turbocharger setup in 91 as an option. Starting in 92 was the factory 6.5 TD with mechanical fuel injection.
