After many kilometres of African travel with our HZJ78 I thought I would post up some thoughts on it and it's modifications. I have noticed that there is always a lot of interest in the “Troopy” in the UK, with a few people asking about them and a (very) few people buying them as people quite rightly see them as arguably one of the best expedition vehicles. I want to try to convey a balanced picture here of the vehicle and the modifications… As we all know, no vehicle is perfect and compromises always have to be found. Likewise with the modifications I hope to indicate what works well and what doesn't.
The HZJ78 troop carrier is powered by the naturally aspirated 4.2 1HZ engine, and has a part time 4 wheel drive system. In Australia they were available in factory turbo versions (1HD-FTE I recall) and are now available with the V8 diesel in single turbo format. Other markets (e.g. African, like mine) still have the good old 1HZ. The engine is renowned for it's longevity and relative ease of maintenance (with the possible exception of valve lash…
. However it is not to be confused with a modern electronic high boost common rail diesel – nowadays for it's capacity it is not exactly “sparkling”! As a lot of troopies end up heavily loaded (with expo equipment or crammed full of people) then you can imagine that it is not exactly an autobahn stormer. Of course the upside to all this is that the engine is fully mechanical and the only electrics are the fuel shut off valve and the starter motor. The engine is also known and understood widely in the less developed part of the world.
