I don't know a whole lot about this conversion but I think it has potential to bea great swap in a FJ40 for example.  It is also relatively smal with little height (it comes from a car) so it would probably fit great into a good variety of vehicles.

There are 240 natrually aspirated diesels but I would not consider one of these since the output is so low.

4x4 Labs in Northern California has a forum dedicated to conversation about this swap.

As of now, there is no commerically available adapter between it and either a Land Cruiser or American transmission.  Supposedly there is a company in South Africa that does currently produce them but I have lost the URL.  4x4 Labs plans to release one shortly.

Feel free to email me if you have any questions, but I do not know a whole lot about this swap.
