Custom Big Bore Stroker DB2 Injection Pump Build

  • $1,800.00


In order to push the DB2 platform to the next level, we have developed a reliable process to increase plunger bore size and greatly improve fuel output well beyond ever thought possible. With rotor options available from .330" to .450" we can build a custom tailored pump for your desired power level. Because of the demand on the parts with these pumps, we use all new components from the housing to the driveshaft to the head and rotor itself, so no core is required on these pumps. These pumps do not retain a fuel screw, however we can add a fuel limit screw to the housing in order to externally adjust power output. These pumps start at 400hp for $1800 and carry a lifetime calibration warranty, so if there is any changes desired to the drivability or performance of the calibration, changes can be made free of charge. These pumps are custom tailored to your specs and built to order, wait times are dependant on part availability. For any questions on these pumps contact us at Sales@classicdieseldesigns, or on our social medias @ClassicDieselDesigns.

 

All CDD built DB2 injection pumps are built to and exceed oem specification. All pumps are built with a new advance piston, metering valve, transfer pump liner, blade set and delivery valve. A common issue with the design of the DB series rotary pump is rapid wear of the advance piston bore due to the hardened piston sliding in the aluminum bore quickly eroding the critical tolerance due to lack of lubricity of modern diesel fuel. Most cheaper rebuilds ream out this bore and fit a larger piston, but this is just a temporary fix and soon the hydraulic advance will be out of spec, resulting in a lack of power, high egts and a smokey exhaust. Our solution is to mill out this bore and install a ceramic sleeve. This ceramic sleeve allows us to create a better fit than with the original design, and shows no wear after over 100k miles, extending the lifespan of the pump, and maintaining the same out of box performance many years down the road.

-If sending a core afterwards, a $200 core charge will be refunded after the core has been received and inspected.
