Ahh, the 12-valve 5.9L Cummins. Probably the most sought-after diesel power plant when it comes to making big, reliable power. The 1994-98 Dodge Ram was very popular when it was still being built and has continued to be even after 10 years of retirement.
None of this emissions stuff, no fancy electrical sensors, PCMs, IDMs or FICMs- just some throttle linkage between your foot and an injection pump. The turn of a screw here, adjustment of some springs there and you're basically on your way to making decent power. Dodge Cummins diesel performance parts, rebuilt pumps, injectors and turbos for your 5.9 and 6.7 L. Rebuilt VE, P7100, VP44 and CP3 injection pumps, injectors and turbos. Oregon Fuel Injection, Bosch and Holset rebuilt and new, stock and performance. Clean injector cylinder head bore with special Cummins wire brush tool or equivalent; Install a new copper washer to bottom of injector Apply a light coating of clean engine oil to this washer. This will keep the washer in place during installation. Apply a coating of anti-seize compound to the threads of the injector holddown nut and between top of nut and injector body; Install injector into cylinder head. ![]() With the recent fuel crisis and price jump in new trucks, we've seen an overload of e-mails and letters from readers looking for ways to get more out of their current trucks. Whether they have fuel mileage or performance in mind, it seems readers just want to see inexpensive and reliable ways to make their older trucks better. We've done builds on a couple Power Strokes, some 24V Cummins stuff and even some extensive Duramax builds. We figured it was about time to go back to the original leader in aftermarket diesel performance, the p-pumped 12V Cummins. In stock form, the 12V 5.9L was actually a pretty strong competitor in the performance department back in 1994-95, but needless to say, it is falling behind in today's standards. Your average everyday 12V would produce anywhere from 180-215 hp in stock form, depending on which injection pump it was equipped with. It was also very limited in rpms and a useable powerband. However, there is major potential in these trucks and we're here to help you find that hidden horsepower. Lenny Reed, owner of Dynomite Diesel Performance (DDP) in Monroe, WA, has been around diesel performance for quite some time. His company specializes in performance injectors, injection pump work and aftermarket turbocharger development. DDP has been in the performance Cummins game for quite a while and has built a 12V Cummins powered race truck that produces well over 1000 rear wheel horsepower on diesel only. Needless to say, the company knows how to make these trucks run. So it was a no-brainer when it came time to build up this 1998 Dodge 2500. While our current plans for this truck include extensive injection pump work and some compound turbos to take it past the 550 hp mark, this part of the build looks at the more basic modifications you could accomplish yourself over the course of a weekend in the garage. Injection Pump Mods First things first. Let's look at the injection pump mods you can do to improve actual output and capacity. The Bosch P-Pump is a pretty eccentric piece of equipment with a lot of little moving parts that need to be dialed in near perfect if you want it to work to the best of its abilities.

While we did all these mods with the injection pump sitting on a bench, they can be done with the pump installed on the truck. First the fuel plate and android housing adjustments. After removing the factory AFC housing you'll find the fuel plate held down with two screws. It's common for most owners to just slide the factory fuel plate fully forward to improve fueling in the injection pump. Actual performance gains from that will be marginal-10-30 hp at best. How To Install Injectors On 12 Valve Cummins Rebuild KitDDP has developed a replacement fuel plate with a completely redesigned profile to work in conjunction with aftermarket injectors and other fueling modifications that we'll get into later. The DDP plate profile is cut to decrease fueling at lower rpms, then get more aggressive as boost and rpms rise. The plate is cut back again to decrease fueling at wide-open throttle for EGT control. With today's injector technology pulling fuel out at low rpms, the DDP fuel plate will help control smoke and egts as well. The 1994-98 12V Cummins came equipped with a few different pumps, the best of which was the 215 hp pump. How To Install Injector On 12 Valve Cummins RebuildOur truck is an early 1998 model with an automatic transmission and came with a 180 hp p-pump. On these smaller 180 hp pumps swapping out the OEM Rack Travel Plug found on the front of the pump with one of DDP's deeper plugs can improve actual rack travel from a stock 18 millimeters to more than 21 millimeters. While that increase of 3 mm may not sound like much, Reed said the installation of the deeper Rack Travel Plug can make a noticeable difference in performance.
