2.5 N/A Diesel into a Series One 80

My non-standard 80 currently has a Series 3 petrol engine in it. I am planning on fitting a 2.5 N/A diesel engine I've got out of an early Ninety into it. . Would like a little more economy so I am tempted to use it more. I just wondered if anyone had already done this. I realise there will be a certain amount of fabrication and extra wiring etc but exactly what needs doing is still a little unknown.

Hi, its a very straight forwar convertion, as you allready have a s111 lump in, it will fit the gaerbox. you will have to move the batery to under the seat, and do a small amount of wireing
