What year is your VX? If '97 or '98 you may have the 3.2L, which you can get out of any Trooper which there are plenty of your way. For that matter, you can get the 3.5L out of later Troopers as well. Better yet, get the 3.1L intercooled turbo-diesel with the 5-speed. Then you'll have an awesome VX that's fuel-efficient to boot!

There's a squarish, black plate riveted to the firewall which has all the build and option codes. I'm not sure what the UK engine code is, but that's typically where to find what's on your Isuzu.
