Nissan/Cummins 5.0 548rwhp/930rwtq!

Pretty big numbers and shows just how restrictive the "made for emissions" turbo is. It says the stock turbo was at 2:1 drive pressure which is good for emissions, but bad for the engines longevity. Same can be said for the 6.7L turbo. Adding a fixed geometry that is correctly sized to the amount of fuel being added not only reduces drive pressure, but also allows you to make more reliable power with lower temps. Adding power does not always mean decreased reliability if done right.


BLAZING A DIFFERENT TRAIL: UPGRADING A NISSAN TITAN XD CUMMINS
  • Technically, the Titan XD is in the same 2B trucks class as all the other current 3/4 ton (HD) trucks and SRW 1 ton trucks from a decade ago. Regardless of anyone's opinion on the matter, it is and 3/4 ton based on its ratings. Just a smaller version with similar ratings of a 5.7L Ram 2500.

    A properly equipped EB F150 can do it's specs or more.

    What does that have to do with what I stated? Not getting defensive, I am just asking because I don't see how they relate.

    Also, I had a custom tuned F150 HD with a 3.5L EB so I know what they can do.

    Yes, it has the same or slightly higher GVWR than my 2000 F250. Big difference is the roughly 5K RGAWR versus 6K for my F250. If Nissan used the running gear from their NV3500 van they would be right up with or higher than the axle ratings of new 250/2500 trucks. But then they would get their lunch eaten in diesel power and torque specs of directly comparable trucks. They are really kind of in a tough spot.

    I haven't understood their positioning since they came to market. The 5.0 is too big to have a significant advantage in MPG like the 3.0 diesel(s) do. And it is too small to have a significant advantage when it comes to performance/towing ability.

    If the one my next door neighbor has is even a remote indication of quality and durability then stay away. He's in the middle of a PA Lemon Law case with it right now. It was in the shop more than out since the day he brought it home for all kinds of stuff, a lot of it electrical in nature. A total POS. Sharp looking though. I don't think he had any "engine issues" per se but the rest of the thing appears to be absolute junk.


    A friend of mine is a tech at a Nissan dealer. He has nothing nice to say about the XD's.

    Rear diff and wiring harness issues are some of the stories he told me. One truck was unfixable and they ended up replacing it.

    He also says he has had to do so many CVT transmissions that he has it down to a science.

    It's a shame because I owned an 05 Xterra we bought new for years and loved it. Stout no nonsense truck that did everything I asked with no issues. Always liked Nissans after that.
  • This pickup was discussed at length here when the specs were released on the little Cummins. I would say that it has turned out just as many predicted....unsuccessful. I predicted that the middle of the road towing specs with HD mpg ratings would be the issue, however what I didn't predict was the issues with the engine and pickup at roll out. Didn't see that coming. At the end of the day, Nissan is stuck. They can or have fixed a lot of the initial issues, but you cant fix the fundamental market positioning issues that they created for themselves, at least with the diesel. They do spec very close to what the HD's speced 16 years ago, but this isn't 2003. HD's have doubled in torque with about the same mpg. So coming to market with a heavy half ton, that gets HD diesel type economy is a loser, and to add insult to injury, that thing has a face only its design engineer could love. Like I said earlier, hats off for going outside the box, but I don't think it was thought through very well.

    It's not a "3/4 ton" truck. The insistantance that this and other half tons by their rated or perceived capabilities make them anything more than they are has worn thin. This truck is pointed right at an EB F150.

    Let's not put it on a pedestal.

    But it is a class 2B truck based on its specs which is the class all other trucks people call 3/4 ton are in. That is a fact that cannot be changed by opinion no matter how adamant that opinion is.

    The 2B class trucks that most consider to be a "3/4 ton" has a GVWR between 8,501 GVWR and 10,000 GVWR. This truck has a GVWR between 8,600 and 8,990 lbs so it is a class 2B truck. If what you deem as a "3/4 ton" is based on payload ratings like it was back in the day when the term had real validity, then it still fits the bill since even a decked out XD has a payload greater than 1,500 lbs (3/4 of a ton).

    I am not putting it on a pedestal and would probably never buy one of these trucks. I am just stating facts regardless of my biased opinion.
