Yeah if it is more then $500, I would rather get a whole new turbo.. and maybe a bigger one..

The good part about geting a stock turbo upgraded is that you don't need to change your wastegate or manifold...if you go with a new T04 or something then you do.

$850 seems pretty damn expensive. I think you can get the rebuild kits for under $200. I was calling a local turbo shop here asking about rebuild kit prices, and they had a new turbo for $550.

i'm not sure how much it costs to send your turbo away to be rebuilt but i know for my turboll it only cost me 111.00 for a rebuild kit from turbo city
