Cummins V8 in a WHAT ?

[retirednak]

Sorry if this is old news. I got my latest Diesel World magazine and it seems Nissan is going to be stuffing a Cummins V8 in their Titan pickup. They claim there is a demand for a performance & torque that doesn't demand jumping up to a HD commercial pickup. Torque rating in the mid 500's, and more then 300 HP. To me, that sounds like a great combo if the V8 doesn't weigh as much as what our trucks have. I could see it putting a hurt on the new Ram 1/2 diesel if Nissan prices it in the same ball park. I'm not into import vehicles, but having owned a couple Z cars and they were in the top 5 of the best built vehicles I've owned.

(I'm looking for a 1976 or older Z car without drivetrain in AK for LS conversion, please PM me)

I found a bit more info.
•Was designed to be similar in size to other gas V-8 or V-10 models
•Uses compacted graphite iron in the engine block
•Has a pair of high-strength aluminum-alloy heads for weight savings
•Offers a pair of thick composite valve covers for strength and quietness
•Employs a dual overhead camshaft strategy with four valves per cylinder
•The Bosch high-pressure common rail system uses sophisticated piezo injectors
•The variable geometry turbocharger design is both simple and efficient
•An all-new advanced ceramic glow plug system is quick and cost effective
•A two-stage fuel system (with dual filters) makes combustion super clean
•The ISV motor uses cooled exhaust gas recirculation, a diesel particulate filter and a selective catalytic reduction setup with a downstream diesel exhaust fluid injection to meet current (and future 2016) emissions standards
Cummins will start production of the new engine at the new Columbus plant by the fourth quarter of 2014, with the engines going into medium-duty bus and truck platforms soon after that. Nissan has not officially announced when the new Titan will debut, and Cummins isn't saying either — nor will either company talk about costs or possible take rates

Problem with Vee type diesel's is they have to rev so high to make any torque, because of their comparitive short stroke. When that happens, they have to burn more fuel.

Maybe when pulling 80k down the road, but I don't foresee any shortage of power in a half ton pick up. I'm still surprised at the difference in displacement between the Ram and the Titan. They are worlds apart in that aspect.



I had a late 1st gen 280z (78) White with tan leather interior. A little slow off the line but once that little inline 6 started making some r's it was a pretty quick little car. We used to go down to Nelsons Ledges almost every weekend where there was a closed road course. Saturday mornings were run what ya bring the only requirement was the car had to pass a general safety inspection, you had to wear a seat belt and a helmet (or maybe dad made me wear the helmet I can't remember) :-laf. That road course was where that Z belonged I could run with a lot of V8s on that track. They might get me on the straight aways but I'd eat em up in the corners.

Nobody is going to know for sure what the numbers are going to be in the Cummins V8/Titan truck. If its tuned to be a performance package, higher revs will work. Sounds like the Titan folks can't make their minds up to try and venture into the 3/4 market. There is a ton of info out there.

I've been searching for a rust free Z car for close to 2 yrs and haven't had any luck. Don't want to stuff a 400 hp LS into a Z car with a rusty frame, or a frame that takes way too much time repairing. The aftermarket makes it real easy these days for bolting in LS engines into just about anything.

A V8 conversion would be cool, but those little inline engines can make some serious speed with minor modifications. When we were going to the Ledges regularly, there was a guy with a 2nd gen 280 with a modded turbo charged 2. 8l. It had been dynod at a hair over
330 horse. He took me around the track for a few laps and that car was smokin fast. IMO the best thing about leaving the 6 cylinder in it is you retain the balance and handling of the car. Not a big deal if it's a cruiser, and all that torque in a light little 2 seater would be pretty cool.

Plain and simple solution ; The big 3 makers and even the imports need to follow the comercial truck manufactures lead put what ever engine it you like , cummins , cat detroit or what ever .

Those inline engines are silky smooth and doesn't take much to make some serious power with turbos. You would be surprised that the balance isn't much different going with an aluminum LS. The inline 6 isn't much lighter once its sitting on a scale. A buddy runs his at the drags,(5. 3 liter Impala SS) and its street driven with a closed off exhaust system. Looking at the car, you wouldn't think it can pull the front wheels off the ground running his ET street legal drag tires? He flips a switch and all hell breaks loose, battery powered exhaust. What will they think of next? I've gone the route using Datsun/Nissan/aftermarket parts for the inline. All I need is a cam change in a 6. 2 liter LS, a few odds/ends and it will make a sweet street car.
