i think 3.4 would be stronger, due to thicker cylinder walls.

This is not correct.
The M104 E36 AMG with HFM from 1993>1997 used the 350SD crank (modified/Lightend)

The M104 3.4 AMG with KE from 1989>1992
Starting with the Win number in a W124 like this = WDB1240311B
Usen the W124 300D crank and not the 350SD crank.
The engine had also rebores to 91,5mm from the org. 88,5mm together with the 300D Diesel crank with the longer stroke of 84mm it gives the engine a volume of 3310cc. as they called 3.4

En Europe called (300E-24 - 3.4 AMG) has 272HK/6500 rpm. and 330Nm/4500 rpm.

This is mixed up by many around the forums becuase they can´t figure that the 300D crank gives 3.4 litter, but the truth is that the M104 3.4 AMG 1989 to 1992 was only a 3.310 litter engine but they called it 3.4

it was first with the M104 from 1993 and the HFM injections system that it came with the crank from the 350SD

The 3.6-24 brabus that I got with the M104.980 engine and KE system.
Has it´s own crank with 90mm stroke and a bore of 92mm giving it precise 3600 ccm.
But they cylinder wall are therefore very thin and that´s why you should not use the brabus headgasket as it is 93mm in the bore and therefore you can use the headgaset from the 3.6 AMG witch is 92mm bore in the gasket and this headgasket keeps tight due to the thicker gasket between the walls.

I have done my own totaly rebiult of my brabus engine and has done a lot with the W124 3.4 AMG as well. so i know these engines very well.

excellent info, and well done for researching it to find out.

i quoted the 'accepted' specs, gained from reading posts over the last few years, just shows how wrong people can be.

do you know which crank they used in the 103 3.2 12v amg?

i was told diesel parts were used, but have never found out for sure.

could that engine (103 12v 3.2) be the 300 diesel crank with out a re-bore?

(does the difference between 91,5mm bore and 88,5mm bore = aprox 100cc?)

For what it's worth guys and gals, the 3.2 M104 crank and the 3.0L OM603/606 cranks share the exact same dimensions.

nick.ged · #49 10-20-2011, 06:57 PM

that kinda makes sense, obviously, when amg first did the 3.2 103, in 87ish, the 104 3.2 didnt exist, so i expect they used the 3.0 diesel, then merc must have thought; if we stick the same dims in a 104, we get a 3.2 petrol engine.

what has never been answered however, is, did they change the material, the early cranks (3.0 diesel) wich i assume is in my engine, were steel forged items, and some have said later ones (104 petrol) are not forged steel cranks.

MAG58 · #50 10-20-2011, 07:21 PM

That wouldn't make sense to me. All my cranks, diesel and gas all have the wide forging lines across the crankshaft. I haven't actually obtained a post 95my engine which is when the big production break was and many cost cuts were made, but I'm fairly confident all of mine, 3.0, 3.2 and my 350D crank are forged. In fact I have a very early production run 3.2 crank and it's stamped 603 on the front arm of the throw.

nick.ged · #51 10-21-2011, 03:57 AM

thats kinda good news, in that my 1989 crank 'must' be forged.

my problem is i have a late 104 engine, it is to be heavily modded for a friend, he is concerned it could still not be a forged crank, as it is defiantly post cost cutting in terms of when it was made.

may just keep a lookout for an earlier one, to be sure.

Bob has also pointed out to us that the later engines no longer had the piston cooling oil jets. (AMGs still did though.)

here is a video showing acceleration

The transmission needs adjsutment so it shifts more firmly.

Also the car have now the amg black origina wheels...will post pictures later

Chlippo · #54 02-07-2012, 04:56 PM

just a bought a set of amg gen1 spoilers with foglights. Its for a coupe but they share the same front and rear spoiler...so i took it.

Chlippo · #55 02-16-2012, 01:48 PM

black oem aero wheels!
and amber tailights.

one of the wheels have a problem with the valve stem and i cant find a new set to replace all 4 valves. If anyone can point me to the right direction it will be great

will those work ?

I beleive the oem valve stems part number is HWA 129 400 01 13

So went to Lebanon and get some things done/repaired on my car.

First i got a new full exhaust (custom made) by using two 52mm pipes, empty muffler in the middle (the one under the front seats approx) and an E55 W210 rear muffler (oem).
The car sounds a lot better now, and the performance feels better, revs more freely now.
Note that the exhaust i removed didnt have the original mufflers, lets say it was messed up a bit. I guess i will later on add another muffler (before the last one) so the sound get less noisy on cruise.

Second was the audio system, changed all the speakers, used cadence ones for the front, perfect fit! The rears were no problem easy to change, but the ones in the front doors were a pain to change. We ended up doing custom braquets so i was able to fit 5.75" 3 way speakers in there. And i added a small subwoofer and a crossfire 4 channel amplifier. I am happy with the results, but i think i can do better with higher quality door components instead of the 3 ways speakers.

Wasnt able to find a quick ratio steering box so i left it as is for now. Also i am confused with the million part numbers those have. Jayrash suggesting getting a C36 steering box, will fit and it is a quick ratio one, but i couldnt verify if it was doable since i wasnt able to find one.

The problem still persist with the ASD pressure accumulator, i will have to order an oem brand new one, i think it is around 200$ at XXXX part number 124 553 00 10.

The new problem is : misfiring.

I dont know what to do about misfiring anymore, it doesnt do it all the time, sometimes it is just a little misfire on low rpm, and sometimes (rarely) the car barely drives, misfiring on all the rpm range. I dont know if its related but i think it happens more frequently when the car is hot.

Note that 9 months ago i got a new oem EHA, rebuilded the fuel distributor, changed both pumps, all fuel filters, emptied and cleaned the fuel tank.
I checked everything and all is working properly...so i left it as is till my next trip.

Also the car sometimes goes really fast, and some other times it feels slow or lets say regular. Engine compression is fine.

any thoughts after this long post?
OVP? Ignition coil?

pictures will follow soon, showing the exhaust tips

Chlippo · #57 05-20-2013, 11:54 PM

So my car started overheating, thought it would be a problem of fans or clogged radiator. It turned out to be the head gasket.

Yesterday, freind a forum member Jayrash had the car delivered at his shop, Confirmed headgasket problem, and the 4th cylinder was full of water.

for those who for long time asked about pictures of the inside of that 3.4 AMG engine, well now you will be served

Here is two that i got from Jay yesterday, there will be more tomorrow

Anyone can think of any upgrades that can be done while we are at it?

JayRash · #58 05-21-2013, 03:52 PM

well took the amg head off, the 34 AMG

.

first thing i noticed is that thou the bore is the same the piston design is different from the 36 amg engine, also piston to wall clearance seems less than on the 36.

secondly the 34 head is ported on the intake side (heavily so), exhaust left untouched. on the 36 its the opposite.

the head runs double spring setup for the valves, and all the parts are on the heavy side. It is like they are made to out live earth

the valve stems are simply humongous, makes me wonder how it revs to 7000rpm but it does. btw reving this engine makes such a lovely mechanical sound that even the 36 doesnt have. it reminds me of M3s and old 911s.

JayRash · #59 05-21-2013, 03:55 PM

some pics of the intake side

JayRash · #60 05-21-2013, 03:58 PM

pics of the exhaust valve vs that of the mitsubishi evo X

no wonder we suffer so many warped valves in the evo
