Or it could be that Cummins had it ready to go and Nissan only had to plug and play? Why go through all the R&D, EPA testing and God knows what else when you can buy a top notch engine off the self ready to bolt in.
And as it was noted in the other thread, the fact that Fred Diaz was let go by Chrysler and then picked up by Nissan. What better way to get a jab in.
Dodge and Cummins have had a long and great relationship, even with Damn-Lire backing out of that same engine for the Ram back in 07. But then they ended up paying for the design and testing work. So my bet is Nissan got a great deal on that engine, good, no great for them!
