Just bought an M925A2, which is a military 6x6 5 ton cargo truck. Has a Cummins 6CTA8.3 (mechanical with aftercooler) in it, Bosch MW type pump.
Seeking suggestions to increase acceleration (power). Truck has a 5 speed Allison auto that shifts at about 2000rpm's. Top speed is 67mph @ 2300rpm.
I have a basic understanding about turning the pump up in several different areas, but I don't understand the correlation between that and adding larger injectors. Also, what about delivery valves? I think I can use a 5.9L gsk kit in this governor..? Would like to upgrade the valve springs but don't know a source.
Also, what is the procedure to check and adjust the pump timing? The gear housig does not seem to have a removable panel where the injection pump resides. Heard 19-22 degrees is fabulous for these engines, but don't know how to do it. Also a source for head studs on this engine. Turbo upgrade recommendations?
Sorry for the shotgun questions. I'm a gasoline guy now in a diesel world. I know I will get told to search, and I will, but it does take hours, and sometimes posting/answering can actualky be quicker. Not always. Thanks in advance.
