Nice link Zeus, thanks! The 4B series of Isuzu diesels are great engines but more suited for full-size pickups 3/4 ton and up as they're fairly hefty engines. I've scoped out some NPR's locally that I've been offered in trade for my Mack Midliner and it's just not suitable for the VX. The 4J series however is another ballgame as that's what came in the Trooper and Rodeo so is a bolt-up proposition. I was sooooo close to getting two of them for one of our VX's and a Trooper but putting our daughter in private school was more important. Oh well, hopefully I'll have a job in a few years!
