The basic advantage of nicosil liners is the weight saving. But the nicosil coating of the alli does wear in time. However at your mileage you should be ok.

A lot depends on what you want to spend, and the best option would be a full rebuild especially if it's an unknown quantity.

I would guess the main reason for changing would be that they run at a significantly reduced clearance, which will also be more consistent, than the iron liners, during all running conditions.  Probably good for noise reduction, oil control and maybe less 'blow by' for the increased boost pressures to come.  Mike - are you aware that the standard iron and Nikasil are not interchangeable?  (without machining).

I was surprised to hear Matt Debage's Excel LC which was an '89 car in excellent condition, but the piston slap was a lot more noticeable than in my rather well-worn HC, so I'm with Chris that it helped maintain a much more equal expansion of piston and liner giving better gap control.  Also the Nikasil lining is so much harder that even in the space of 100,000 miles you don't loose all the honing marks and so it keeps a better oil coating in place.
