Stock IDI Turbo DB2 Injection Pump Rebuild
The stock IDIT rebuild mirrors the factory calibration for the 93-94 turbo IDI pumps, with all the reliability upgrades that our street series pumps receive, without the need for a pyro or boost gauge. 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.
