The 4HE1 replaced the 4BD2 which replaced the 4BD1 in the Isuzu line of NPR trucks. The 4HE1 itself has also been superceeded in 2006 by the 190 hp 5.2 liter 4-valve per cylinder, fuel rail injected 4HK1. I think each engine represents an improvement in power, fuel efficiency, driveability and reduction in emissions. I personally am intererested in the 4HE1 because of the possibility that mating to the Landcruiser drivetrain may turn out to be very simple (at least for the automatic tranny). And I certainly don't mind more power.
Another consideration in pursuing this approach is that, if the AW450 automatic transmission can be easily adapted to the LC drivetrain, it opens up a whole bunch of possibilities for diesel swaps as variants of the AW450 transmission were used in Nissan and Mitsubishi trucks (similar to the Isuzu NPR) which could make these engines candidates for swaps into Landcruisers.
