Imho, I'm no expert by no means, but the advantage to me would be mileage, and the coolness factor of having a diesel jeep, the kubotas I've delt with are very fuel efficient and very reliable. I would think a turbo charged model would be better than a L head at higher elevations. But, most kubotas, like most small diesels, run at 3,000 rpms max, and really dont have any power to about 2300 or so. that would mean 45 MPH with stock gearing and transmission, without a OD, and have other drivability issues. I'm sure there are fixes for these issues, but rebuilding a l head isn't that expensive. Again, just my uneducated, just judging by experience opinon.
