The Gen I 5.9L Cummins 12v in the 1988-1993 Dodge Ram trucks is what started the diesel truck revolution. The early 12V engines with the Bosch VE6 rotary pumps are great engines and they'll last forever when taken care of. They're easy to work on and with a small budget you can get some respectable power and torque out of the Gen I Cummins. We still work on these engines providing service, maintenance and performance upgrades all the time. In fact, a few of our crew members still own a Gen I 12v Cummins. Fortunately, there is still an abundance of genuine OEM stock replacement Holset turbochargers available for these trucks. If you're doing some fueling upgrades such as fuel pump and injectors, then our Holset aftermarket performance turbo upgrades are a must. When it comes to the 1988 - 1993 Dodge 5.9L turbochargers, you have come to the right place.
