200tdi conversion for our LandRover 110

We are thinking about converting our broken and horrible slow 2.5 n/a diesel engine from our Land Rover 110 to an upgraded 200tdi from a discovery (or better from a defender). But where to start?

Our new 1984 Landrover 90 has had an engine swap, the 2,5 was converted to a 200tdi from a discovery and it is a great change! It drives fantastic, it's much easier to keep up with traffic and great off-road. The only thing we have to get used to is the Right Hand Drive... but that's quite easy and a lot of fun too when overhauling on motorways

With this experience we are looking for a 200tdi engine and a lot of other parts because our old 110 is an ex-militairy (navy) vehicle and therefor 24 volts...

By the way I found this great link on 200tdi conversion
