I owned one of those for over 10 years and it never let me down until the LSD got a bit tired towards the end - 330,000 klms will do that and perhaps I shouldn't have been there anyway.
Lifts are easy on them if you keep it to about 50mm. The front torsion bars will crank up that amount and still keep enough travel to be be useful. The rear coils are easy and cheap to replace.
You need to keep an eye on the shocks, especially the front set as they are undersized and will wear out very quickly.
PY mentioned the timing belt - this is critical for this engine as it is an interference engine (the valves WILL tangle/bend/hit the pistons) if the belt pops where the older 3 litre engines would usually survive as they were not interference engines. Get the water pump done at the same time. This is not a cheap job, expect to pay close to $1,000 for the wrk.
Spark plugs - these were platinum plugs and also due to be replaced every 10,000 klms. They can be substituted with cheaper plugs if you want, but good plugs are important to this engine to keep it working well.
Other than that - enjoy it. It has a nice turn of power and works well on high speed bitumen and dirt roads.
