On a few other diesel forums, much to the aghast of several members, the issue of Izusu diesel conversions have come up with favorable results. Especially the 4cylinder variants in vehicles with limited length under the hood. The basic opinion is that they are very durable motors that have much less vibration than the 4BT cummins. Searching for engines, they are quite available in auto trim as opposed to the 4BT, I guess that is because they are seen everywhere around town in delivery trucks. NPR's and GMC medium duty. The opinions site the best motor as being the 170 hp version, but I believe it is computer controlled. Just wondering what the thought is on this site. I have seen one 4BT in a jeep. It would crawl a wall and rattle your fillings out. As dental work is expensive, my initial impression caused me to cross that one off of my list.
