4020 CBC Injector pumpHELP

[riverrd]

I am needing a CBC-633-38AL pump, this 4020 has an aftermarket blower and has a 4520 pump. The 4020 usually has the 18AL or 28AL,, anyone know where I might find a buildable core or a conversion kit to the new style pump,, or will a 18AL or 28AL work with the installed turbo,,,, thank you

The 38AL 4520 pump has 7 degrees pump advance, and full load fuel flow is 85-90 CC at 2500 engine speed. The 18AL is for the 4020 synchro trans, has 8 degrees pump
advance, 60-63 CC flow at 2500. The 28AL 4020 PowerShift pump has 8 degrees pump advance, 70-72 CC full load flow. The main governor spring is different on the 38AL pump
too for less speed droop. The 18AL and 28AL could work with some internal parts/roller setting changes.
