Feeler: $1,000.........I am currently having some stock n54 turbo's rebuilt with waste gate upgrade and whatever else is required by my local indie. Next week he will swap those out for my current 108,000 mile stock turbo's. He is going to clean and rebuild those with the waste gate upgrade and whatever else is required. He will warranty them to one year. You would just have to send them back to him. Let me know interest. I am not looking for money yet but serious interested buyers to gage interest.
