I know when my turbo went in my 05, the shop I took it to replaced it with an aftermarket for $1,500 only to find out 2-3k miles later that my up pipe was plugged.. which the shop failed to catch and damaged the new one. After that, due to the plugged up pipe I nuked a valve which nuked my #2 piston. Resulted in having to replace the piston, the crank, heads were sent out for polish/check for cracks. Short block was good tho so we rebuilt the entire engine with new seals, timing belt, etc and a used turbo for $3.8k.
