    • BigBoost readying Stage 1-3 W205 C63 AMG M177 V8 turbo upgrades

      The AMG M177 turbo upgrade market is really heating up. BigBoost Turbo is a new vendor over on the BimmerBoost side of the network but they also are tackling Mercedes turbo upgrades. Specifically, the W205 C63 AMG M177 4.0 liter V8.


      There will be three upgrade stages as detailed here:

      Stage 1: Just impeller change, 46mm 7 blade, billet aluminum.
      Stage 2: New shaft with larger turbine and compressor: 46mm compressor, 48 mm turbine.
      Stage 3: New turbo (CHRA, compressor housing, turbine housing) reusing manifolds, 49 mm compressor, 49 mm turbine.
      The most exciting stage there would be number three. They are going to try to get some big turbochargers in there and it will be interesting to see how it all fits. The housings compared to stock in the photos look huge.

      Re-using the factory manifolds will certainly simplify things and lower costs but it all still has to fit.

      This is going to be an exciting upgrade to watch develop.

        First - thank you for coming into the AMG 4.0L bi-turbo market, I believe it is a great platform, and the more vendors we can get involved, the better for all.......more sales, more exposure to the vendors involved and exposure for the vehicle, and the competition will make vendors create great performing products.

        I do have a question as it relates to Stage 3. With stage 1 and 2 I see it making sense to use the stock manifolds, but for the higher flow you will be getting out of the stage 3 turbos, what have you seen for flow rate capability from the stock manifolds? I am curious if it is ideal situation with the bigger turbos, a way to keep the cost down and maybe performance is secondary, or is the manifold development not there just yet and something we may see in the future?

        We are considering to make bigger manifolds in the future, but stage 3 is a little further away than stages 1 and 2, so when we release stage 3 we may have considered to change manifolds.
