Hello Spoonie,
Yes it is a pretty well deserving project. The Nissan Diesel conversions have been done before and the engine and gear box of the Nissan SD33 is stronger than the Land Rover one of the era. Certainly more fuel economical than the 2.6 litre Land Rover motor. The chassis is on Hunter is immaculate too. The Series Land Rovers are just like adult sized Meccano sets.
Kind Regards
Lionel
