    • Weistec M113K forged pistons now available (E55 AMG W211, 55 AMG kompressor models) - $2099.99

      Here we are, forged pistons now available to satisfy those with the W211 E55 AMG looking for big power or for anyone with a supercharged 55 AMG who has concerns about reliability when pushing big power with their 55 AMG M113K kompressor motor. The improvements these pistons offer are larger ring lands, improved dish, improved piston skirts, and revised wristpin mounting offering more strength yet less weight than the OEM Mercedes-Benz AMG pistons.

      9310 Steel wrist pins which are stonger and lighter than the OEM setup are included and compatible with the stock rods. The piston rings are also designed for a motor that will be seeing big boost.

      As you can see in the photos, the pistons are ceramic coated on top to aid with heat resistance and the skirts are also coated with teflon to reduce friction.

      Less weight and greater strength means a motor that will handle much more power and also rev quicker and more easily. Combining these pistons with the Weistec M113K 3.0 liter supercharger upgrade is really a no-brainer for those looking to get big power (reliably) out of the M113K platform.

        I think it's definitely a smart move no matter what. I mean, why not?

        When did they figure out that you need this in order to turn up boost?

        I don't know if you *need* it to do that but it certainly would offer piece of mind. Guys have popped M113K's with the stock blower...

        Our supercharger system is limited by factory internals. If you want to run at the true potential of our supercharger, it is the natural progression to build your engine.

        The broken factory piston pictured above was actually from a car with a stock supercharger system and very aggressive tuning done by another shop. The margin of error is very slim when it comes to the factory pistons and added power, not to mention the 100,000 mile engines that many customers currently run. This is a very easy option for those seeking quality in stock parts at an affordable price.

        You still *need* to build the engine in order to turn up boost and run full potential. There's no way your going to do it on the stock bottom.

        I do not disagree with you.
