Interesting! I just happen to have a good turbo 4BD1T sitting around...The Austriallian Military used that engine, but generally its a non-turbo. But it could be swapped out. I've found a few Austriallia EX-MOD's in the UK. I haven't purchased them due to the engine. And I'm not sure if customs would freak out. they basically look up the engine number to make sure its a Land Rover engine. If its not a Land Rover engine, they won't let it in.
BUT- you can remove the engine, and ship it all separately. Then it just becomes parts. And the process of importation becomes 50% easier.
