Kevin from JCSports here. My MY98 had the following damage: warped block, cracked heads. I was able to take the supercharger kit off and return everything to stock before taking it back to the dealership for a warranty long block. I am aware that there was a problem with the #4 piston "walking" in the cylinder but that was not the reason for failure. I put a temp probe on the outside of my intake manifold after a normal 5 minute drive and it read 490 degrees! That is what caused the damage.
