The Magnum 5.2 Liter OHV SMPI V8

The Magnum 5.2, released in 1992, was an evolutionary development of the 318 with the same displacement. The Magnum development included the multiport fuel injection, new cylinder heads with a closed combustion chamber, a new higher-flow valve angle, increased valve lift, and new intake and exhaust manifolds. Power was up to 230 hp (170 kW) and 300 lb·ft (410 N·m) of torque.


Availabilty of the Magnum 5.2 L in the Dodge Durango ended with the 2000 model and was replaced by the new 4.7 L PowerTech V8.

Production itself continued of the Magnum 5.2 L but finally ended with the 2003 model year of the Dodge Ram Van.

The 5.2 L is easy to spot as it uses a smaller top rounded fan cowl mounted to the Dodge Durango radiator if compared to the 5.9 L.
