Its a Honda Passport based on the Isuzu Mu (Mysterious Utility). Trooper 3.1 non-intercooled 4JG2. Trooper axles and Mk.I trooper SWB chassis. Chances are its also got a rear LSD as most of them were fitted as standard. It also has aircon. That means that you will struggle to fit a front mounted intercooler (from say a Frontera) as the air-con condenser sits in front of the radiator leaving no room, and there isn't enough room to fit a top mounted intercooler as the bonnet sits too low. Top mounted intercoolers have been retro fitted to the Mu in the past, but you have to get creative with a grinder and the bonnet then fabricate a scoop.
Honda took the Mu and rebadged it. You will struggle to find parts for the MU and they tend to be expensive ... unless you know that a lot of them are actually Trooper bits

Rospicer is finding this out with this one until he spoke to me

BTW those alloys are as rare as hens teeth and came in two sizes of 15" and 16". The yanks pay good money for them to fit onto their Troopers. They are the Isuzu pepperpot.
