This place is a joke.
FWIW the documentation I read today from MB shows the 55K engine is 9:1. The 55n/a was documented as 10.5:1 as you already stated.

Has the AMG community not accessed the world that revolves around getting aftermarket pistons into an alusil block?
I am all for building with stock pieces, but it seems like for the compression ratio needs, getting a forged piston in there with whatever CR you want for about 200 bucks a hole with rings seems like a very good option.
Lighter weight too. No one is breaking rods that I can see. Crank is fine. Its head gaskets and Pistons right?

On the E55 oil pump, have you figured out the function of those two pipes that go to the rear pan?
When I did my engine replacement I had to swap over the E55 pump and pans to an S55 engine. I did not have time to figure it out, but if you did, what are those two pipes doing?
One would make sense is a suction pipe to pull oil from the rear sump, but what is the other one doing?
If one is a suction pipe, why does it not have a screen over it like the front sump pick up??
Just seems something got a little over engineered there.
Oh, more pictures of the girl please....

I think that's the discharge for the internal pressure relief valve.

There is a screen in there. It's just before the oil from the rear pickup tube hits the rear pump gears. When I changed my pump I though the same and took it apart since I'm a curious *******.

I'll make another post later with more pictures of the build process, but at this point it's really similar to assembling a standard M113k since the short block is complete.

Alright, home from vacation (regretfully), so it's time to get back to work.
I installed new OEM bearings (M113k) on the M113k rods because my originals were showing some wear. The M113 bearings didn't look great and they had the oil port for the strange rod oil passage which is not seen on the M113k rods. These suckers are EXPENSIVE, absolutely the most costly part of this experiment.. especially if they can't be reused when I blow up. I called Clevite to try and get them to give me more information about the OEM bearing but the politely told me I had to go through Mercedes. In the future, I will try to find a less expensive but equally capable option.

With the rotating assemblies labeled and ready to go, a light coat of oil on everything and in they go. Had absolutely no issues, rotating the crank after installing every cylinder.

With the short block assembled and the oil pump system resolved, the heads went on. I have the M113 heads on due to the damage caused to Cyl 2 bowl on my M113k heads. This also keeps the combustion chamber consistent/piston height consistent with stock M113. I transferred the M113k valve springs, retainers, and keepers over but kept the M113 cams and cages.

With the engine assembled, it was time to go back in the car. I did notice one difference that should be noted. The first picture is the M113 flex and the second is the M113k. Obviously, these are not interchangeable due to the fastener spacing. I did make sure that both flexes had the same overall diameter, offset, and tooth count so the stock starter can still be used.

The motor is in the car now, still need to throw the headers on and button a couple things up. I'll update when it fires up, shouldn't be too long

wow I really admire the skills you have to pull this off. Do you have any MB technical references to work off of (how to do you know the torque specs and etc?) Great job in detailing the work! Can't wait to see you fire this thing up!

Then there's always just physically getting the parts in my hands or referencing some of our other knowledgeable members like Ahmad (blackbenz), Steve (amgrocket), Chris (Boost a lot), Brad (Greasemonkey), Dennis (denroll) or the guys at BIP. We're all in this together, advancing the platform, and these are just a few off the top of my head I've been able to call on
I'll be pushing limits of stock components so it's likely that something will happen eventually. I'm telling myself it WILL happen so I'm not so bummed when it does, hahahaha. I'd like to at least be where Ahmad was when he started popping N/A longblocks with my M113k bits sprinkled in, but it's always better if I can beat him at his own game

I think you will be able to hold alot more power with the M113k pieces in the motor. I'm really excited about your build

I believe w211 m113k motors comp was measured to. 7:7:1 by Steve.
That's hella low, can't wait to get you a new tune homey and see what this behemoth puts out.

If the motor ever lets go (I hope it doesn't) then the haters will say you don't know what you are doing because you blew a motor
. Forget the fact that you are making wayyyyyy more power than them.

Might want to consider putting an engine diaper on it just to be safe.

If it holds with the stock blower on 16psi (my current setup), I'll be spraying it pretty good. Craig has seen good results on just a 50
I'm using the M113 heads so it was a no brainer and I didn't have to measure any clearances. If anything, at least in my past experiences N/A cams on the same motor platform will be more aggressive to squeak out a little more power. With the blower, this wasn't needed on the M113k so the cams could be more reserved. I suppose I could get everything measured or swap in the M113k cams later to see if there's a noticeable difference... it would only take like an hour.

I really believe people when they say the M113K has low compression. I can tell you this, when get up to speed and take my foot out of the throttle the car does not slow down. Even down shifting it does not want to slow down.
Just the opposite for my C63. When I close the throttle on that car is really slows down and when you start down shifting it feels like you are putting the brakes on. I know the C is much lighter and the engine is bigger, but there is a very clear difference.

I'm pretty confident it will hold. And yea I tried a 50 shot a long time ago (back when I was in the 11s lol) and when sprayed through the blower you see massive gains! But to see the most gains you have to spray it out the hole and get it to hook. The 60' is the most important part
