    I have a 2009 BMW 535I. I was watching one of the YouTube videos and I was curious of the cost to rebuild the both of mine and the turn around time ? I would also like to know how much more it would cost to upgrade ?
    Thank you Randy

      We rebuild them with the Wastegate repair for 650$. Usually it takes 1-2 weeks also have cores on hand, but I’m out of the 5 series rear Turbo right now. I will try to find another one.

      We currently cannot do that, because I don’t have a machine to machine the exhaust housings,
