The R2.8 Turbo Diesel is a powerful 2.8-liter 4-cylinder engine targeted as a cleaner and more efficient alternative to many older original gasoline and diesel engines used in iconic small pickups, SUV's, 4x4's and more.  The combination of low end torque, low fuel consumption, low engine operating temperatures, modern high-pressure common rail fuel injection and compact packaging makes the R2.8 Turbo Diesel the ideal engine to power your project wherever your adventure may take you.

The engine comes dressed with a power steering pump, 120 amp alternator, camshaft-driven vacuum pump, grid heater, and engine-mounted passive diesel oxidation catalyst. In addition to the engine itself, the kit also includes many major components necessary for engine operation, including a universal wiring harness, engine control module, accelerator pedal, OBD port, and a digital J1939 data display.  The installation documentation provides guidance for right-sizing the engine cooling package required (radiator and charge air cooler).

Please read all emissions information for the desired part number prior to purchase as Federal emissions laws apply.
