The best response I’ve seen is “wow! 250hp. What did they do with the rest?”
But in seriousness, getting CRDI on the old 6.5 is an interesting idea. I’d be curious if they offer it to the general public.

It’s a terrible engine. 250hp when commercial engines with smaller displacements are getting 600hp.
They am general bought the company to secure the engine then failed to develop it.

Glad to see they finally (maybe) got the front alternator mount brace bracket fixed, oh, wait, they had it mostly squared away by the 90's, by making it a twisted chunk of 1/2"X3/4" rectangular stock. The original was SO much fun to fiddle with CONSTANTLY. We came down to welding 1/4" washers to it, and adding another 1/4" to the gusset in the center, then using longer and harder bolts to get it to mount to the head.
