Engine weight for M113 engines?

Where can I find information regarding techical data like engine weight (kilograms) and HP/NM numbers for different M113 AMG engines?
Engines which I need information for are these: 113944 - 113980 - 113986

Does 113980 engine differ a lot in weight versus C43 engine 113944 because of bigger displacement?

I think M113 (5.4l) around (1,710kg),,

while M113 (4.2l) around (1,640kg), but NOT that sure..!

you mean 5.4L engine has an approximately weight of 171kg and 4.3L weights about 164kg?

what is the torque/RPM's for:
4.3L = 410NM @ --------?
5.4L = 530NM @ --------?

*5.4l (1,710kg) = (3,790lb),

*4.2l (1,640kg) = (3,615lb),

as i know;

*C43 torque is (302 lb-ft) at>>(3,250 - 5,000 rpm)

*E55 torque is (391 lb-ft) at >>(3,150 - 4,500 rpm)

engine might be around 200KG's heavy?

my car has a registered weight of 1630KG + some extra weight from add ons

how much did c36 with I6 engine weight?
do both engines differ a lot in weight between cast iron VS aluminium?

Wikipedia is your friend but I haven't found the weight....
https://en.wikipedia.org/wiki/Mercedes-Benz_M113_engine

Checked around but couldn't find any precise figures. Estimates talk around the 130-150kg bracket

I'll have an unused 4.3l engine to weigh soon, if possible

Still would like to now the difference in weight between 4.3/5.4?
Since December I own a Carlsson Cm60 has a m113 that is a 6.0
To me it doesnt feel more nose heavy at all, Im surprised! Might be a bit heavier but not noticable!

im not an expert by any means, but if its the same engine block with different bore and stroke and maybe cams the weight should not be all that different. so the M113 C43, CLK55, and the 6.0 i would assume are all within maybe 20lbs/10kg maximum of each other?

somewhere in these forums there was a link to a post on some other site with tons of mercedes engine weights (just the engine), lots of old old engines. i do remember looking and finding that the 113 engine was something like 200lbs lighter than the I6 from the C36 due to the aluminum vs the cast iron block.

I concur that the weight difference between the 43 and 55 is probably minimal. The weight talked about is that for a full engine, i.e. with all the surrounding ancillaries including manifolds, or just "naked"?

I agree, I dont really see why it would be alot more heavy (lets say over 10KG)
Always loved my c36, but im surprised with the weight of the M113

am I crazy, or would the higher displacement engines weigh less than the 4.3l? the cylinder the decreased bore of the block would indicate that overall more alusil is present in that engine, and there is less alusil required to cast a 5.4l engine. increased bore = more air in each cylinder right?

in theory yes the higher displacement would weigh less. but again it should be very minimal. we are talking about shaving only 1-2mm of material from each cylinder wall to increase the displacement 1 liter or more, that isnt gonna shed much weight. I still stand by my statement that they all should be within 10kg-10lb max at most.

heres a link with some wiights, but they are all older, im guessing the 1995 and back inline 6 is not much different than the C36 I6(??) none of the M113 engines are on this list though.
http://www.gomog.com/allmorgan/engineweights.html

very hard to find engine weights online apparently, but the Chevy LS is a very popular engine that is offered in 5.7 and 6.0 liter variations, online it seems the best numbers i can find is that the 6.0 is 450lb and the 5.7 is 457... but lots of variables there can change the numbers if they arent measured with the same components attached.
