Take one owner with tony blair grin.
add boost and get....
some bore damage, unfortunately. quite a lot of the piston ended up deposited on the bore walls, but underneath, there is some damage to the bore wall. the heat's also damaged the top of the rod, so that's gonna be replaced.
As far as the cause goes. The inlet manifold gasket's spilt on no.1, and looks like it was pissing the charge out of it. that'll make it run a load richer than the other 3, stuff start's getting damaged. Rob was getting very bad fuel consumption, as the lambda reading's would be leaner than the target map, and the ecu compensates by adding more fuel. meltdowntastic!
