This is happening too much especially with my luck lately! Sorry to hear... On the dyno I was running 12.2 - 12.6 AFR. Thinking I should send ECU back to LET for re-tune...

Had the same on mine. replased 2 pistons. Suspect the eurocharged tune provides detonation with low octan gas. Car moded almost same as Rasim's 178mm puley, short headers, K&N filters.

a lean tune will cause detonation. Usually piston ring will blow and scratch all the silicon off the cylinder walls. The pistons and rods seem robust enough to take the detonation vs the ring.
This is assuming you had a aftermarket tune.
You can bore out the block to a 3.7L and then sleeve with larger pistons and lighter rods or you can just buy another used engine.

in my case (same as Rasim's) ringgs were ok but the wall between 'em gave a way
PS. Do u mean 5.5k piston and rods?

what caused your walls to give out? My pistons and rods were fine. I lost the silicon coating on two of my cylinder walls, but other then that there was no real damage to the cyclinder walls for me.
I would just use stronger custom pistons and rods.

i guess you can just buy airfrcd's motor. He's selling it for 3k without the sc. Its probably cheaper then rebuilding it.
