The Gen I 5.9L Cummins 12v in the 1988-1993 Dodge Ram trucks is what started the diesel truck revolution. The thing is, these 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 out of the Gen I Cummins. We still work on these engines providing service, maintenance and performance upgrades all the time. In fact, two of our employees still own a Gen I 12v truck. Fortunately, there is still an abundance of genuine OEM stock replacement Holset turbochargers and Holset aftermarket performance turbo upgrades available for these trucks. When it comes to the 1988 - 1993 Dodge 5.9L turbochargers and turbo accessories, you have come to the right place.
