2016 Titan XD Cummins- TFL

I could see the ISV being used in more motorhomes and light duty commercial trucks. The big thing that Nissan has exclusivity on is the "M2" sequential turbo system that Cummins developed. That was developed specifically for Nissan as the ISV in commercial operations have a traditional valley turbocharger setup. Don't know if the exclusivity is because Nissan asked for it, or if Nissan locked it in as being the sole owner of it. There's a few other small differences between the ISV and Nissan motor, but the blocks are exactly the same.
