I'm dumping my powerstroke for a cummins soon and would like to know from just what to look out for. It'll probly be a 99-02. Also whats the deal with those early 24v and the common rails and the mechanical pump motors? How do they compaire and who makes the best chips? This will be tough to do since i've always been a big blue oval fan, but i know it will be right!

first off welcome to the cummins family... second the difference between the 12 valves and 24 valves is that the 12 valves are all mechanical from mechanical lift pumps to mechanical injection pumps so on and so forth..... the 24 valves use electric lift pumps and stuff like that.... and finally things to loo for in a 98.5-02 cummins is if you buy one buy a fuel pressure guage asap and do not let your fuel psi to get under 5 psi or you'll most likely be replacing your injection pump shortly which isnt cheap..... anywyas i'm sure more people will tell ya what else to look out for also

VERY cheap to make power. Lift pump should be upgraded if it doesn't have the in tank pump (don't seek out a pos intank pump)

The Cummins engine can support MASSIVE power without getting into the engine, and pretty good power with cheap mods (like mine! :)) NO MORE PULLING THE CAB for injectors/valve covers! ONLY synthetic in the new venture six speed, and get an extra quart in it. The 5 speed nv might have the 5th gear walk off the shaft from the nut walking off. You MUST have a steering stabilizer, and it SHOULD be between the axle and the draglink. (Some were from the frame to the draglink and this may have "death wobble" show up)

Don't let me talk you out of it, though. I knew these problems and bought mine! Otherwise good solid trucks. The six speed is close enough ratio to be a pain to drive, but VERY stout. There are two versions; The older has a 1.25" input shaft, the newer has a 1.375" input shaft, larger clutch and pilot bearing. It can be identified by a (1.5"?) spacer between the starter and the bell.

Dodge Ram Information is a great site to cruise around on with VERY reputable information.

thanks for all the info. I am very familliar with the death wobble, as I am a big Jeep guy. What year did they start putting the intank lift pumps? I'm looking at a 99 2500 with a 5 sp. ALSO what year did the Killer dowel pine end?

That year has the 53 block thats the one you dont want and that 5 spd is the one that lets go I think look for an 02.Comes with 6 spd and good Block.Aloha Ron There is also trucks for sale here just ask abd most times with mods to fuel pump and injectors and so on already to go.My bad thought 99 had the 53 Block....

KDP ended in 1998 i believe and they did not start the intank lift pumps until 2005. So pretty much any truck from 98.5-2004.5 MUST address the lift pump cause it is only a matter of time before it fails. Not as bad with the common rails since they have a sensor and will just shut down when fuel pressure is too low, while the fuel lubed vp44 will starve itself to death. Just a heads up. :thumbsup

thanks, so any 24v should be fine? And if i get a 12v, the kdp is a lengthly but rather simple fix right? I've seen write ups about it.

Some other difference include:
- 2005 and below 3rd gens had the plastic intercooler, went to metal in 2006.
- I believe, starting with 2003 or 2004, IP was changed to CP3. Prior to this, 3rd gens used the VP44, I might be off on the exact year. CP3 is a stronger pump, not sensitive to input fuel pressure like the VP44. The VP44 likes fuel pressure in the range of 7-15 psi. You get below or above that, damage can occur to the pump.
- Also, I believe in 2004, the HO version of the 5.9 CTD because stock in the ram.

All 3rd gens are HPCR and thus CP3, which started in 2003.

Yes in 04.5 all motors are HO and 50 state. The motor was relatively unchanged from 04.5 to 07, and was rated at 325/600(610)..

:agree2: the electrical connections changed on the 06-07. In 2005 the torque was bumped up to 610 and some of them had plastic intercooler tanks and they changed the valve bodies in the transmissions in that year too...I think...

The 04.5+ have a larger compressor on the turbo, a third injection event, some minor air flow improvements in the head, a 4" TBE and a cat to boot....

Yeah they went to the CAN ECU vs the ??? (can't recall)...

Also the 6 speed manual changed in 05 as well. I have a 05 with plastic end caps and a NV5600....
