110cc (300hp) DB2 Injection Pump Rebuild

  • $999.00

The 110cc Db2 is the best in terms of budget friendly performance. Retaining the same flat fueling curve of the smaller street pumps, this pump makes 110cc fueling flat across the entire rpm curve, reducing egts compared to other 110cc pumps which run 20-30cc more peak fuel than hp fuel, creating a smokier, hotter running pump for the same amount of produced power. Capable of over 300hp and 700 ft lbs, this pump will take any IDI well into modern diesel performance standards. Upgraded turbo required, intercooling recommended. 

All Classic Diesel Designs' DB2 injection pumps are built to and exceed oem specification. All pumps are built with a new advance piston, balanced metering valve to reduce side load and stickage issues, low lubricity spec tool steel blade set and transfer pump liner to reduce wear with modern dry diesel, high torque shutoff solenoid, viton material grade seals, updated delivery valve, delivery valve stop, and low lubricity grooved plungers.

See Stanadyne service bulletins: S.B 60R8, S.B.108RlO, S.B.125R5, S.B. 304R8 S.B. 334R1, S.B. 373R1.

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.
