Upgrade internals in stock turbos?
Sorry everyone, I'm on my phone so I can't do a search....
I've owned a couple Audi and VW turbo cars and I know people would upgrade the stock ko3's with different internals at a cheaper cost than upgrading to ko4's or others and was wondering if anyone has done this with our turbos? Reason I ask is I'm starting to hear the siren sound so I know at least one is slowly starting to disintegrate itself.

Mechanically speaking the N54 is a fucking champ. There are hundreds of 400+whp daily driven N54s running around and, AFAIK, there is yet to be any mechanical failures that are related to increased power output.
Hell, even the record holders are stock.

Rob Beck or Vargas turbos will be your best bet. Vargas has upgraded WG shafts and better seals than factory. RB sells one version of stock-housing turbos, and Vargas sells a stage 1 (very close to stock with upgraded internal seals, WG parts, etc) or a stage 2 with increased flow, similar to the RB turbos.

It has been emphasized to me by one of the vendors that the siren sound is *not* normal, and that it is likely that they will need to be replaced in the near future. However, I have heard the siren noise on tons of non-BMW vehicles, so, I don't know. There does not seem to be a general consensus on this. I only hear the siren noise at low turbo RPMs when the engine is cold. After about a minute or two, the sound goes away for me. I have had this sound for around 10k miles, at least.
I, myself, am debating between Rob Beck and Vargas. I do not need anything as extreme as a single turbo setup. |

I siren everyone is refering to in this Video is just normal turbo spool. When a turbo is going it sounds like a dentist drill, you will know when you hear it.
