For Trooper diesels the trick is finding the right OEM engine. The '92 is still 1st-gen (IIRC) and you're in luck there since the '86 Trooper was available in the US with a turbo-diesel. Since Isuzu is primarily a heavy-truck producer, and also use most parts extensively cross-platform, you can actually use the engines from the NPR series of medium trucks. I believe the 4BD1TC intercooled engine has been used with a good deal of success with the Trooper and Rodeo. Troopers look pretty good with the hood-scoop for the TMIC!

since these are all Isuzu OEM diesel engines already in domestic use they're excellent swap choices. I've been specifically looking at the newer 4GJ2 since the VehiCROSS has the TOD system and that was the combo used in overseas models.
