By combining one of the most reliable and heavily modified injection pumps on the planet with the better flowing cylinder head of the 24-valve, you can build the ultimate high-power hybrid Cummins.
What’s the difference between a 12 valve and a 24 valve Cummins?
In place of the P-pump was a new, electronically controlled injection pump from Bosch called the VP44, and the cylinder head now contained twice as many valves as before, giving the 1998.5 to 2002 Cummins ISB its nickname, the 24-valve. What’s the Difference?
