The 9-3SS has very light pistons, if you had a piston fracture I'd suspect lots of detonation.
This is usually due to faulty ignition coils (one of my techs drives a 9-3 Linear with BSR software in it that came in with 2 coils malfunctioning, the detonation fractured the ceramic in the spark plugs, and cooked the ground electrodes off all 4 spark plugs, which got chewed around inside the chambers for a while ---> fresh cylinder head time).
Check the plugs very carefully and see if there are any speckles or melty looking spots.
Check fuel pressure and check that all 4 injectors are flowing correctly too.
I assume it took the block with it when the piston fractured?
Best,
Drew
