Hello,
I've removed the N55 from my 2011 535xi due to a bad rod bearing and would like to refresh the turbo before I put the engine back in the car. Are there any local shops in Minnesota that you like and recommend that specialize in turbo rebuilding? Thank you. Steve
While new to the world of BMWs, I'm quite accustomed to turbo rebuilds for other vehicle brands.
A great shop right over the river in Wisconsin is Midwest Turbo Connection. I typically rebuild my own turbos as I want to know precisely the parts put into them. What I'm unable to do is the balancing to the rotating assembly, so I first went there to have a balance performed. The shop is incredibly clean and organized. That's indicative of their services. I would recommend you give them a call and ask for pricing. If you really want to add longevity to the rebuild, and some faster spool times, replace the standard bearings with full ceramics. A bit more pricey, but well worth it, especially on cars such as these BMWs.
