Just wanted to start a thread to discuss the M113.5.4 engine (5.4 N/A AMG) and it's flexibility in subtle or heavy modification.

Quick Wikipedia search says they came in the following:

• 1997-2000 C 55 AMG
• 1998-2001 SL 55 AMG
• 1998-2002 E 55 AMG
• 2000-2002 S 55 AMG
• 2000-2003 ML 55 AMG
• 2000-2003 CLK 55 AMG
• 2002-2006 CLK 55 AMG
• 2001-2002 CL 55 AMG
• 2002-2003 G 55 AMG
• 2004-2010 SLK 55 AMG
• 2006-2008 SLK 55 AMG Black Series
• 2005-2007 C 55 AMG

Please share your experiences if you have any of the cars listed above and explored tuning, no matter how big or small of a job..

I've researched the following is what makes it different to the standard Mercedes 5.0 M113:

• Stroked to 5.44 litre
• Forged Crankshaft
• Strengthened connecting rods
• Connecting rod journals are 4mm further from Crank
• Piston stroke increased from 86mm to 92mm
• Reworked cylinder heads
• Lighter weight camshafts with longer duration
• Stiffer Valve springs
• Larger better flowing intake manifold
• Improved exhaust system
• Compression ratio increase to 11:1

**correct me if I'm wrong on anything above or missed anything**

Better intake, headers, decats will all reduce restriction but is it worth the gains?

How do these units respond to remaps?

Do the partially forged internals lend itself well to forced induction or is the compression ratio too high to consider that?

If you enjoy naturally aspirated power delivery and sound, what else can be done to improve performance?

I usually tinker with cars from 80's - 90's, so are there any electrical things, i.e sensory equipment that can be adjusted/changed/removed to improve performance?

Thanks

 

Absolutely worth it, I'm doing all of that and some more. I should be starting a thread on it soon.

I just started my build log if youd like to check it out.

 

i just started my thread under c55 it has the amg charger on it
