New guy here in the market for a Cummins!

Hey guys, my name is Dave and im currently in the market for a diesel truck. This is a great forum u guys got here and there's a lot of good info. Ive been reading thru all three sections of the diesel engines (ie ctd, psd, dmax). Right now im really leaning towards buying a dodge 2500 diesel either a 12 valve or a 24 valve. Now the question i have for u is which valvetrain is better of the two? Also ive found a lot of the 5speed equipped ones and i was wondering if this is a good route to go. Ive heard that dodge early auto trannies were pretty weak. Also what other common problems have u encoutered with the 98-02 models motors? I work on Cummins powered generators and they are the most reliable engines ive worked with but now id like to get into a truck that i can have some fun with and tow my Mustang that ive been building. Well any help is appreciated and i cant wait to start burning some oil!

Dave

The thing that goes wrong on these trucks is the VP44 (injection pump). That is the main thing witht these that goes wrong. It pulls a code: P0216 so don't buy a truck that is setting that code! Mine is setting that code and it makes my truck worth it's weight in scrape.

It is, a good upgrade is putting a FASS fuel pump to save it. That cost around 700 bucks. That is must on these trucks, you get everything from them though, awesome filtration, fuel economy, power. You could do that FASS and HPVP44 that is a slighty beefed up VP44 but those run around 1600 bucks and according to Schieds will give you almost a 200hp increase in just itself. Or you could do a conversion to a P7100 injection pump which makes holy grail of your engine and runs around 5000 to convert. From there where you want your power is unknown. The P7100 is what they put on 12 valve Dodge Diesel from 94-98 and certain MACK trucks. And probably other stuff. The best beefed up VP44 injection pump has nothing a STOCK P7100. They are super tough pumps with room for improvement.

There are other fuel systems that are just as good cheaper that you can look into. Click the link in my sig to check out the Performer series fuel pump.Performer

The Schied Lightning HRVP has gave 103Hp over a stock pump and 274TQ in 05 on a guy I knows truck. Look here

If you are smart and shop around you can do this conversion for less then half that price. Like everything you have to shop around for the parts.

wow thats a lot of cool info out there thanks guys! One thing im confused about is u guys are saying that an upgraded IP will actually add power to the motor? Doesnt the amount of air from the turbo stay the same, which would make it run richer? Im kinda confused about that. Also as far as the actual motor w/internals how much power can it support w/o digging into the internals?
