Forged internals?
Who knows for sure what parts of a W208 CLK55 are forged inside the motor? I've heard a whole bunch of different answers. Anyone that knows for sure please chime in. Forged pistons, rods, etc?

blackbenzz, I can't meet your standard of proof (sorry) and you may have already heard this, a few of the 2001 CLK55 car magazine articles described some of the engine parts this way:
"The CLK AMG is powered by a hand-assembled 5.5- liter V8 engine. The hardware list reads like that of a race care: super-stiff forged billet steel crankshaft, forged, weight-matched connecting rods and pistons, lightweight AMG-specific camshaft churns inside the pressure-cast aluminum block of this chain-driven single overhead-cam V8......"
If the article writer was correct then the crankshaft and connecting rods and pistons would be forged.

AMG built one hell of a LUMP!!! All the factory Benz mechanics I have ever spoken to say they have never seen one fail and they are bullet proof.

Want to bet? I have a CLK55 that just today is having its engine removed due to no compression in the #6 cylinder. NO ENGINE IS BULLETPROOF! Parts fail and there is nothing you can due to eliminate it.

Your car is supercharged isn't it? Has any stock 208 CLK55 engine failed?
Not saying that it wouldn't or couldn't as any engine can but no one has posted one here......

...........the problem is not forging. The cylinder walls are extremely, I mean really really extremely thin. The rods are very thin. The cylinder walls have a special coat that is incompatible with aftermaket rods and pistons. As a result you cannot just get upgraded pistons and connecting rods. Best to stay with your engine as is, or rebuild everything including the cylinder walls.

..........Yes. The pistons and the cylinders have a nicoseal coat. You can bore the cylinders. That will get rid of the nicoseal coat. You can then get larger after market pistons which do not have a nicoseal coat and you are good to go. You cannot just get non nicoseal coated after market pistons and use them with your stock cylinder wall. I have taken apart my W210 engine block and the cylinder walls are extremely thin. The oter wall of the cylinders are no reinforced. Boring it to get a larger displacement for NA maybe ok, but for FI will be crazy. Maybe the W211 block is different.

What about using the 4.3 or 5.0 M113 to build up?? Using the same M113 block and having a smaller discplacment would usually mean smaller cylinder bore and thicker walls correct?? Which would leave more room for opening things up?? I'm no expert, just a thought.
