Nissan Repair: A Diesel engine instead of Benzin, dear sirs, nissan serena

Question
Dear Sirs, I have Nissan Serena 2.0 benzin and would like to ask you if there is any trouble in changing benzin engine to diesel.
Which one fits better 1.6 D, 2.0 D, 2.3 D?
Any other replacement to be done?
Many Thanks,
Shukri

Answer
Shukri,

If the diesel will fit you are there and I would go with the 1.6 and make sure that you have the harness that goes with it for the changeout.  Also, you will need to make sure that the fuel system is adequate for the change to include the proper fuel filter for the diesel and the pressure requirements of the diesel are met.  You need to make sure, as a minimum, that you get the harness for the glow plugs and the timing circuit along with the temperature sensor to make the change.
