cams look good, I will likely finish my 113 with high compression pistons first since that car (2003 s55) is the most completed. But this twin turbo setup for my w215 is after that. I’ve since picked up some ARP head studs for the w215 build
spoke with the cam shop and the cams should be done soon
in the meantime I decided to start putting together the second engine, the original junkyard CLS55 block and crankshaft that’s been mentioned through this thread.
here’s a nice before and after photo… after some odd miles and a car fire, then to me lapping the cylinder walls, cleaning the block and getting some paint on it.
so far on the second engine I have gapped the piston rings much wider, cleaned the rods and pistons, balanced the lightest rods to the heaviest pistons, installed the crank bearings and I have to get ready for the piston oil squirters. I have about 8 piston squirters I’ve found so far, from different 113 engines. Not all of them match, some are slightly damaged from previous install attempts, but these squirters are no longer available to buy so I have no choice but to make something work
Where did you get all the bearings for the engine? I’m rebuilding my E55 motor and I can’t find main or rod bearings anywhere. Anything is much appreciated I want to get my car back on the road.
haven’t finished the original 113 I discussed in this thread. Had an exhaust manifold stud shear off when installing a supercharger and better exhaust manifolds (that don’t leak) onto my 2005 e500 wagon. I ended up using the ported heads from the original engine on the e500
i did get close to finishing this m113k block with the higher compression amg 55 pistons, street beast cams, another set of ported heads. Water pump just showed up for this engine. Hoping to have it installed in my 2003 s55 soon
Looks great! Cool build. This is my first reply/post. I was wondering, just like someone else had asked earlier in the thread- what bearings did you end up using for your crank? I’m really looking for a set of rod bearings for my M113K, that came out of a 2006 S55 AMG. Seems like Mercedes has completely discontinued them, and every place online that listed them ended up having zero stock. Even Mercedes classic center.
I’ve thought about even trying the standard bearings from a standard m113 engine… scared to try that though. Any leads are much appreciated! Good luck on the build

there are a few aftermarket companies developing bearings for the the m113’s right now, at least connecting rod bearings
in the meantime look into m113 55 amg n/a variant connecting rod bearings and the m113 55 n/a and 500 n/a engines should use the same size main crankshaft bearings. From comparing 55 n/a and 55 m113k bearings the main difference I have found is m113k bearings seem to have an additional “coating”. I would venture to believe there are more high tech coatings available these days anyways for bearings compared to what mb used in 2003 for these engines
Long time no post, thought I would update this thread… I am usually more active on the amg Facebook communities. And trying to upload some photos of this finished engine are reminding me why…. Apparently uploading 20 photos takes over 20 minutes. Not to mention these forums are a bit archaic in the fact that you can’t mention certain vendors unless they pay for advertising space here. All good things must come to an end
i have finished rebuilding this engine from the cls55 that caught on fire, however instead of putting it into my w215 I have decided to put it into my 2003 s55. The w215 engine is nearly finished and I will post that soon as well
2003 s55
-modified e55 long tube headers and X pipe
-ported amg 55 heads
-55 amg cams
-n/a 55 amg rods/crank/piston for higher compression and less overall rotational mass for faster revving (plus it’s what I had available)
-widened piston ring end gaps 2-3x that of stock as the only thing that seemed to hurt these pistons before under 10ish psi of boost, was the ring end gaps were too tight
-stock s55 supercharger/surge tanks
-vtech Ecu tune
I have yet to run the car on the dyno, but so far it is running great with no check engine lights. With the high compression pistons, the car is extremely quick to spin the tires even with 285 tires mounted in the rear
I have decided the custom license plate for this car will be “HICOMP” because of the pistons. And the w215 using the m113k pistons will have a plate that says “LOCOMP”
