There's no real clear and easy source for information on diesel engine turbo conversions and all I can say is if planning a turbo conversion, it should not be taken lightly and good research must be done!  You might want to check out this page on a HJ60 turbo conversion.  If your engine is piston skirt cooled it also makes a better candidate for turbo charging.

Turbos in diesel applications very a whole lot less you have to worry about when compared to a turbo setup in a gasser and honestly I think all diesels should be turbo charged due to it's relative installation ease and lack of side effects (though a naturally aspirated diesel is easier for daily driving).

Here are two very interesting articles from the DTLC all about Turbos:
