They aren't.
While the engine is fine for those kms just remember the whole car has done 300k kms, check over the suspension and bushes.

So some Gu's are NA are they Winnie???

A GU 4.2 TD will do what you want and more
very hard to kill them, keep the service intervals
up use all the correct fluids and it'll last you ages.
As Winnie pointed out remember the rest of the car has done 315k
thats wheel bearings etc. A member here brought a 98 model with lift
33" tyres roof rack 4.2 TD and a few other bits and pieces ready to do the Cape for
$20K, so see how you go
