Before deciding on the 4JB1-T 2.8 liter turbo diesel, looked into the delivery truck engines and even helped a friend in NC remove one. Those engines are huge diesel clunkers that weigh about 800 lbs.

The 2.8 TD is so smooth, it's hard to tell it's a diesel. The timing belt is replaced in less than an hour. We installed a Ford Tarus SHO alternator that puts out 200 amps and got rid of the little alternator with vac pump that puts out only about 80 amps or less.

I drive a manual 300 TDI 110 daily and the Isuzu 2.8 auto seems to have a lot more pickup and more top end in the RR. The Isuzu 2.8 TD in the 110 was much much faster, but didn't quite match the 300 TDI at highway speeds being about 5 to 10 mph slower at max possible speed with the petal all the way down on both vehicles.
