I would say that any changes to the oiling system can hurt the car if it's not done correctly.
For example, I installed a remote oil filter and oil cooler setup that I designed myself and killed my motor. I had high oil temps that led to a spun bearing. I still haven't sorted out exactly how or why I had an issue, my oil pressures looked fine but under high lateral G's my oil temps would spike. The likely issue was that I was using too much plumbing in my oil routing, along with too many 90 deg fittings (apparently every 90 deg fitting acts like 10 feet of line). So while I was seeing good oil pressure at my sender (which was installed early in the oil filter relocation block), by the time my oil was getting to the bearings it was likely low on pressure. But since I hadn't properly instrumented for oil pressure, I don't really know what happened.
My current setup uses a higher flow JDM oil pump, much less plumbing, a much larger oil cooler, only a single 90 deg fitting, and my oil pressure sender is in the block allowing me to see the actual pressure in the journals rather than seeing the pressure in the remote filter. Now I'm not seeing the oil temps spike under high lateral G's. But I'm also not driving the car as hard these days since I'm just running PDX's instead of competing in Time Trials.
So, an off the shelf kit that's been designed and tested shouldn't hurt anything if it's installed correctly. But piecing something of your own together could present issues even if installed correctly if all the parts don't work together just right. My original setup looked fine on paper as it was assembled from all the "right" parts, but when installed still led to issues.
