Cummins 4.5 Engine Stats

The 4.5 is based on 5.9L architecture, similar to the Cummins 4BT. The diameter of this diesel engine is the same as the 4BT and the 6BT/ISB minus the stroke being longer in length. This engine was build for industrial applications.

The engine shares the same bore diameter as the 4BT (3.9L) and 6BT/ISB 5.9L. However, the QSB 4.5L features a much longer 5.39″ stroke, versus the 5.9L/3.9L’s 4.72″ stroke. The Diesel Engine was designed for industrial applications, though it has attracted some attention for engine swaps. In terms of its likelihood for a conversion, the largest downfalls are the electronic controls and relatively low availability.

The Cummins 4.5 Engine Specs:

– Inline 4 cylinder B series
– Displacement is 275 cubic inches
– High pressure common rail injection
– Holset Turbocharged
