I'm very sad to see those shocking pics, esp. of the cam journals.

What are you going to do now? Throw the turbo out? A turbo system is only as good as its tuner is.

I went CTSC 10 years ago on an engine with nearly 90k miles and had some kind of feelings if I ever will regret it in the future. I did the install myself. FF: after 10 years and more than 40k miles the engine and CTSC are still going strong. All 6 still at 14.5 bar in a compression test. No troubles, no nightmares, just a few Gatorback belts, new fuels lines and an idler (plastic) pulley as preventative items. Not sure if the (non-OEM) cats needed to be replaced last year but not a nightmare.

Good luck with wherever you're heading to.
