It can and has been done but I can't help with any details. The Cummins motors are very heavy and would need much heavier front springs to hold the weight.
theres alot of diffrent engine conversion and doing a cummins conversion is the most exspenive
so i think you need to think about what your going to be youing it for
Hay guys just a question with the lower revs of the cummins is it worth getting the patrols gearbox gear ratios changed or just change the whole gearbox
I think it depends on what model of engine, ISF 3.8L or 6BT 5.9L or something else? Apparently the 6BT can pretty much destroy the GU five speed box so may be best to replace the transmission at the same time.
