90cc DB2 Injection Pump Rebuild
The 90cc DB2 is the best pump for bolt on performance. This pump is the best compromise for those wanting to upgrade from stock, but may not want to upgrade turbos or intercool. Best suited to be used with a boost and pyrometer gauges, this pump works perfectly with an otherwise stock powertrain. Built with the largest stanadyne "stage three" leaf spring, this pump is still fully adjustable from its out of the box setting 90cc fueling at 2800 rpms, and over 100cc peak, with a 4000+ rpms defuel.
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 issues 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.
