Two Questions
Glace has some more questions.
Still in the hunt for my perfect C43-36.
I noticed today a C43 from Ontaro Canada on Ebay(120133814532)
that has a front bumper that I have never seen before-Kinda cool and it may be off another model MB. Please enlighten.
Also this question was posed to me by my E55 Buddy.
What is the difference between the AMG C43 motor and the standard 430 motor.
From what I know thus far- it is balanced and blueprinted.
Is the comp. higher? cams higher lift? I am sure it's something.
Thanks Gang.

'99 C43
I have the 1998 dealer's technical sales manual on the 1998 C class cars. It describes the C43 engine mods. The engine is a "stock" 430 sent to AMG where they add oil squirters to cool the pistons, AMG spec camshafts (hollow shaft), and an enlarged intake. The engine management software is also changed. I think it also state's that larger injectors are installed - but I can't remember for sure.

Though I can't answer for the lightness of internals, the redline is the same. This is not really a high strung revvy motor by any stretch of the imagination. Just a sweetened "430" motor. The torque is great, and it pulls hard down low

I wonder about the intake as I have one open at the moment getting ported and polished from an ML. I bought a spare to be worked on and I have my original in the car running. When I bought this on ebay the seller had it from an ML430. I got the part # and confirmed with the dealer that the intake part #'s are the same for the ML and the C43. Once I got the part in hand I compared them and the AMG sticker is even there also.
So this makes me wonder, are the same intakes used? or did my intake really come off of an ML55 and the seller had no idea?? Maybe more M113's used this intake piece?

Port Away
looks like You may have opened a can of worms on this ML Intake. Being a Porting addict-do you have any photos and from a flow point of veiw can you find any flow disruptions that the handy dremmel can take care of.

I just looked up the intake manifold part number, and for a C43 is it:
113 140 07 01
The E55 uses the same part number. Then I checked some random engines like CLK430, ML430, ML55, and they are all subbing to this number now, so apparently it is the exact same part for all these 113-engined cars.

This makes sense....as I remember hearing (I'll check later when I get home on EPC) the C43 has few to no HWA parts, compared to the C36 which had many. So that would mean that they used normal MB parts, like seems to be the case here

There is plenty of improvements that justify removing this piece and working it over. For example, one thing I did different than mbenzman was the shafts that run laterally across the throttle plates. This shaft runs across both cylinder banks and has a half round bar and 2 screws that create disturbance once the throttle plates are open(I propbably need a picture). These are now smoothed to a much lesser profile along with low profile screws that create less of a "hump" for the air to pass over.
...glad to find out I didn't just waste my time working on a regular M113 intake and not something special.
