C43 with 209,XXX miles. how many does yours have?
Mixing old with the new, are any of you C43 guys running the late 430 throttle body? If so, care to comment? - specifically, how much vacuum are you seeing on the dyno @ 5800 RPM
For those that don't know, in 2001 when Bosch ME 2.8 was introduced, throttle body size was increased. Those engines were equipped with the AMG 55 sized throttle bodies (before the flame wars begin, the AMG E55 TB itself is a different part, but the "size" of the non-AMG part was increased to match it in 2001). The larger TB was a closer fit to "the optimum" TB size for a 430.

I cast mostly Silicon Bronze all the time and have never been exposed to an Aluminum-silicon alloy as of yet. How are the strength characteristics compared to a general cast aluminum, might switch my melting metals! Thanks Marcus
oh, btw, my friend just got a c43 too after drivin' mine..why you think?
( this friend is marko )


now sell your c36 and get a c43.will be the best mod you can do ROFL
The Best of Mercedes & AMG
I’ve got a couple of press blurbs about it, and they claim Alusil is much stronger than aluminum. Kolbenschmidt Pierburg AG (the developer of Alusil in it’s current state) claims that Alusil is so strong that Audi main cap threads are cut directly into the block. When the bolt is overtightened, the bolt snaps but the threads are still good. Alusil is supposed to have twice the tensile strength of aluminum (the exact wording was "100% stronger", but I think that's the German to English translation for "twice").
I said they are both good in their own ways.
And yup I drove his, very different,, but remember I said "different" not better...
""now sell your c36 and get a c43.""
Ummmmmmmm NOPE!! thanks anyways though. I bought a C36 AMG because I want a C36 AMG, not because I want a C43.... lmaoooo
Why, well first there is the characteristic of the I-6 it feels like a V8 low down but screams all the way to 7000RPM. and the sound track it makes is really sweeet.
Secondly there is the way the car feels on the road, proper sports car, C43 is more refined, isolated.
Thirdly, C36 feels faster (prolly is not) but it feels more responsive.
In the end both are sweet rides.

Do u know what TB size an AMG36 1995 with ASR has? and is there any larger one that might fit from the other mercs of that time?

I can tell you how to tell if you will see any benefit from a larger TB though. Run a vacuum line from the intake manifold to a vacuum gauge – one that your passenger can see while you drive. Do a few WOT passes in second or third gear and post the reading.

BTW, what about the AMG engine description for the C43 describing tuned intake plenum and lightweight connecting rods (hand built AMG) for those than can't read. These docs came with my car.
