Isuzu Troopers >'99 have a very clever 3.0 DOHC common rail diesel designed by Caterpillar that produces about 180 bhp and does 30mpg but self destructs in many, many creative, expensive and terminal ways. Great when it works though. The earlier Troopers had a 3.1 engine that was nice, reliably but thirst and even earlier was the 2.8 4JB1T that is great, noisy, quite slow and very frugal. It often ends up (or used to) as a transplant into Defenders. I have a 2000 Trooper retrofitted with the 2.8 which is a great bit of kit if very agricultural
