Bring your first-gen 5.9 12-valve Cummins to life with Diesel Power Source performance parts. Our turbos and exhaust manifolds are precision-engineered to deliver quicker spool, lower EGTs, and long-term durability. Designed to fit 1989–1993 Dodge Ram trucks, each upgrade improves airflow and efficiency without sacrificing reliability or driveability.

 

If you own a 93 Cummins, you're working with one of the most iconic 12-valve engines ever made. The 1993 Cummins, often found in the 93 Dodge Cummins trucks, features a T3 turbo flange stock—important to know if you're upgrading to a T4 aftermarket turbo. 

 

Most '93s came with a VE rotary injection pump, known for its simplicity and fuel economy, though many enthusiasts swap in a P7100 for better fueling and horsepower. 

 

Engine bay space in these first gens is tight, making Diesel Power Source’s compact compounds or Add-A-Turbo kits a perfect fit. Since most 1993 Cummins trucks didn’t come with a factory intercooler, adding one is crucial for EGT control and performance.
