Stripped the engine down today to try and find out what happened.

Firstly did a compression check and had 180 across all cylinders which was a surprise, but when I looked into the bores it was clear that something had been banging around in there. The pistons and head had massive chunks taken out of them and there was vertical scoring along the bores. There was some small blank chunks of metal pressed into the head and bits kept falling out as we stripped the car down.

I pulled the turbo and split it and found that the turbine had broken apart. The turbine material is a match with the small black bits of metal, but what I can't understand is how exactly they got in there. I would have expected them to go straight out the exhaust but they have made their way into the combustion chamber.

Annoyingly when we pulled the cam covers off the cams look perfect, almost like new! It's a shame that this engine has survived so much only to be taken out by a Pumaspeed turbo :(

Picking up a replacement engine next week and will hopefully get it fitted over the weekend. I'll go back to stock turbo for now so it runs, but will be going S280 in the near future.
