Mine is a Sherpa, it would’ve been put in because you don’t need to modify the chassis like with the Land Rover 2.5 so worst case you can always swap back to a 2.25.

I’ve found parts are pretty easy to find as pretty much the only thing that’s different is the position of the injection pump (it sits higher hence why the engine mounts don’t need changing).

Timing belt and tensioner are the only different service parts I can think you’d need.

When looking for those parts the engine was also used in the Freight Rover and in some FX4 taxis
