The install would be much more complex, plus, if your going to P pump the 24 V, you would lose most (not all, but most) of the reason for getting the 24 valve. Add into that that most 98 and 99 and some 00 and 01 24v should be out of the question due to the "53" code brazil block that likes to crack and your going to have a hard time finding a good one. I can tell you that a bone stock 4wd 2500 dodge extra cab long bed has power to spare with the P pump, which means in something as light as a j-truck, that engine will have PLENTY of power.

Something for everybody to keep in mind though. These diesel engines were built to tow in trucks, or for the economy in cars. Other than the new CRD engines, they are not rocket ships. Bone stock they are only going to rev to about 3 grand and it will take them awhile to get there. Its in their design and the fuel they use. I'm not going with a diesel swap, even though I am a diesel mechanic, for just that reason. Gas engines are for horsepower and fast revs, diesels are for torque and pulling. Use your Jeep for mud much? You'll be watching your turbos puke up there turbine wheels. Live in a cold place? startings gonna be fun. I hate to burst anybodys bubble, but those diesels you see in the magazines have a ton of $$$ put into them to make them handle that power. And if your not a diesel mechanic, repairs are more expensive. If the injection pump goes out or starts leaking which will happen to the older pumps when run on the new standard ULSD diesel or bio-juice, your looking at $1000 plus to fix it for parts alone.

I'll get off my soap box now. I've just seen way too many people buy diesels to be cool and think that out of the box they act like the ones in the magazines only to end up either selling them because they can't afford the repairs or blow them up because they don't know what theyre doing.

Ve pumped 12v's can be strong performers, especially if they are in a vehicle that weighs 2500 lbs less than my 2005 3500.
The real advantage of the 12v is simplicity and longevity, neither of which can be applied to the common rail engines.

My 12v should be about 350 hp 600+lbft when everything is done, it should be a reasonable performer
