1976-80: International Scout II, Traveler and Terra
For 1976 International introduced a diesel option to the Scout lineup. The Nissan CN6-33 6-cylinder diesel debuted at the same time as two long-wheelbase Scouts, the Traveler SUV and the Terra pickup. The engine came from Chrysler-nissan, which was a joint distribution venture between Nissan Motors of Japan and Chrysler Corporation. This agreement lapsed soon after the IH agreement and distribution reverted to Nissan. The Nissan designation for the 198ci NA six was SD33 and it was one of a family of four- and six-cylinder diesels used in a variety of applications. From its introduction in Scouts through the 1979 model year the SD-33 was naturally aspirated and rated at 81 horsepower. For 1980, the last year of the Scout, an uprated 6-33T turbocharged version was offered and rated at 101 horsepower. The diesel was a relatively popular option in Scouts and the engine created a stellar reputation for reliability, even if it wasn’t a powerhouse.
