    Default My C250 coupe build thread [UPDATE P3]

    Allow myself to introduce... myself!

    I am making a build thread for my car so I can keep a diary of my car and so you guys can maybe learn from some stuff that I will do or will be done to my car because the C204 is a fairly new platform for tuning.

    First off Iíll introduce myself. I am Niels, 27y old and I work as a sales manager in a car parts store in Belgium, where I live. I have been active on this forum for some while. Most of the time in the W203 forum.

    I have a W201 190d EVOIII project/show car. Was also featured in a Mercedes Tuner magazine (I'm waiting for the car to be considered an old-timer for the Belgian technical inspection so I can legally do an engine swap)



    And a W203 C200cdi. Daily driver/ring toy. Will also be featured in Mercedes Tuner magazine. My dad bought the car from me.



    I bought the C204 because I love the lines of the car and the facelift nose. I chose a 250cgi because I have been driving diesels my whole life and wanted a gasoline engine now. From my point of view this engine is easily tunable because of its turbo. In Belgium it is forbidden to tune an engine. So it isn't that noticeable that my car is tuned when it already has a turbo. I didn't buy a C350 or C63 because the price of the car, taxes and gasoline is to *******g high here in Belgium! You can get a C63 in the US for the price you get a C250 cgi here.






    I bought the car in July and I have been loving it since then. First mod I did was the Burger Motorsports air filter. I did this just for the sound. I know it will suck in more hot air now.


    Second mod was a C63 style grill with distronic star (from Superstyling.eu on Ebay) and replace my D1S xenon bulbs with 6000k replacements.


    (Behind the C204 you can see my beater Opel Rekord E1 2.3d)

    Since 12 November my car has been staying at Eisenmann research & development and to produce the a quad exhaust for the C250cgi and get it homologated. They are still working on the CAD drawings and calculating the sound. They told me that they have a difficult time getting a great sound from the engine. Probably because it's a turbo I4...


    I will pick up my car in 2.5 weeks and then it will probably stay at the KW factory for research and development for the first KW DDC ECU coil over kit for the C250cgi and to get the kit homologated.


    I have already been discussing with a known Saab tuner in the Netherlands to tune my car. We have agreed on a custom intercooler, oil catch can, reworked turbo, A45 AMG injectors, custom downpipe with race catalyst and a custom mapping. After that I will take a look on what brakes and wheels to get.

    That brings us to today. I will keep you guys posted with the updates that Eisenmann will give me. When I receive my car I will record a clip to show you the exhaust note.

    Then I bought a complete brake set (calipers, pads, disks) from a W204 C63 AMG with Performance Package with a burned out engine. Disks were milled down to remove a bit of rust from standing outside and to check if the disks were warped. Pads are still good. The set had only 37.000km on them.

    Then I received an email from Eisenmann with 2 pictures. I think it looks great :-) I could have picked a smaller size of exhaust tips, but I like these. I'm hoping that it sound as good as it looks.

    So I got up to drive to the Eisenmann R&D factory to pick up my car and bring it to the KW factory. The roads were clear and no snow, so we where lucky. After arriving at Eisenmann and completing the paperwork, they showed me my car next to an all new 911 with Eisenmann exhaust. All I can say is that Eisenmann delivers top notch work! And they are very helpfull. I asked them to put the OEM exhaust in the back. And they wrapped it all in so it wouldn't damage my trunk together with the plastic plate that used to cover the hole where the right exhaust is now.



    After seeing the exhaust in person, I can tell you guys that the picture made the tips look bigger. The size and placement of the tips is perfect! I tried caputering the sound but it was very windy and the exhaust has to be driven for 400km, after that you will get the sound that the exhaust will produce the rest of it's life.

    We thank the people of Eisenmann and wanted to leave. They warned us about a snow storm coming so we needed to hury to the KW factory as my car has been in Germany before the winter and now that it's winter, wintertires are required by law... We still had open roads driving to KW and I felt that the exhaust give a better pick up when the car downshifts. Overall I can't tell if I can feel any hp gains because I haven't driven the car for almost 2 months. I enjoyed driving those open roads with curvy corners and great views trough the mountains.



    We arrived just in time at the KW factory because the snowstorm was coming in... We did the paperwork on the car and I handed over the keys to the lovely lady working there and said goodbye to my car for another 2 weeks. They will be installing the KW DDC ECU kit on my car. Yes everything at kw is purple and yellow :-) And they put the screws from there coilover kits in their christmas tree :-p



    So when we departed home we had to drive back to the highway trough those curvy mountain roads in a snowstorm... So we got delayed for a bit! I'm hoping for no snow when I pick up the car! I have 18" wintertires ready at home to put on my OEM rims... I'll need to find a sollution next week. I still have some 18" Brabus wheels, but I don't know if they will fit the calipers.



    So overall I can tell you that the Eisenmann exhaust is worth every penny and looks great! I don't even doubt that it will give a slight HP and/or NM gain. We still have to wait for the sound it produces but givin the fact that Eisenmann can simulate the noise it will produce, it will sound great. To bad the weather and the timeframe didn't make it possible to shoot some pictures or make some soundclips.

    Nice sled! I'm excited to see how the C63 rotors and calipers look.

    Friday 21 December we departed in the early morning towards KW with a new set of winter tires to mount on my 18” OEM coupes wheels. This time we didn’t have a snowstorm…



    Once we arrived at KW, I got the whole presentation off the KW DDC ECU coiloverset. It’s high quality like you expect from KW and the ECU with Wi-Fi is very small. The hardness button is in the spot where the cigarette lighter used to be.



    The alignment and height of the car has been done by KW. In front I still have enough thread left. In the rear I couldn’t really see how much thread was left because apparently you have to take out the rear spring to adjust the height… I will be looking for a solution in the future.





    Our car his pumped up steroid brother was also at KW... I saw 4 C63 AMG Black Series coupes that day. They make our cars look like sissies :-D



    As we still had some time left, we went to the Mercedes museum in motor city Stuttgart. I really recommend it! Even if you aren’t a Mercedes fan.



    The building itself is a real beauty! And the evolution of the engine is explained wonderfully! There are even some things that are explained with interactive stuff like an exploding airbag or the principles of a hybrid car. I took some pictures. I’m not posting everything as I don’t want to spoil the experience for someone who wants to visit the museum.















    Then we drove home and I had some time to play with the KW DDC ECU kit. The change in dampening is the same moment you press the button! And when you push it the color of the ring changes, to indicate in what mode you are in. Comfort (blue) is the First one, this is a little bit softer then the OEM suspension on our cars. It is extremely comfortable for long drives or daily driving. Sport (KW purple) is the second mode and is a bit harder the OEM sport mode. Sport+ (rood) is the last mode; it’s harder than the OEM sport mode. It isn’t that hard as the Bilstein B16 PSS9 kit on my W203. The Bilsteins didn’t have that much travel. The KW kit has a bit more travel before bottoming out. So it isn’t that bouncy. But I could be comparing apples with oranges as it is a complete different platform. And I haven’t really adjusted the kit with my IPod to see if the Sport+ mode is the maximum in stiffness, so it could be comparable with the Bilsteins. I will answer this in the future.


    Once I was almost home, I opened up the windows and roof, eco off, sport mode on and manual gearbox. I downshifted and accelerated to hear the exhaust note. The exhaust sounds deeper and darker now. It isn’t loud. Because it is the sport version, not the race. It is more noticeable then the OEM exhaust. And it doesn’t give a drone or an irritating tone when driving on the highway at a constant rpm. I still have my catalyst and an Eisenmann central dampener. The cat will be replaced with a race version. I will see if the exhaust sounds the way I like then before removing the center dampener. I don’t want to remove it now and then get to loud when replacing the cat. I will be recording some sound clips with a decent camera. I don’t want to give you guys a distorted exhaust note when recording with my HTC One X.
    Friday evening I arrived at home late from Stuttgart. I unloaded my car because I asked for some promotional material from KW to put in our shop.

    The next morning I was on the road to KCPerformance to get my ECU read out. They also took some pictures for their website and apparently I am there new timeline picture on Facebook.

    http://www.facebook.com/KCPerformance?fref=ts





    After the small photo shoot they tried to access the ECU via Canbus. This didnít really work so we took out the ECU and wrote down the part numbers and such. They will be ordering a new ECU to send around to get a program written to crack the ECU. So then my car wouldnít be sitting there useless without an ECU.



    I took time to enjoy my car again as I have been missing it for 2 months. I really like the KW DDC ECU system. I donít have to compromise now or get under my car to adjust the dampening. The Eisenmann exhaust is the perfect size. I have been standing next to a C63 and I think every C63 could use a more aggressive exhaust. The exhaust note is great for a standard coupe. Once I have more than the standard 204hp I might like it a bit louder.


    Here are some pictures of the stance and exhaust. Donít mind that the car is dirty! I washed it but if I drive it for 5 minutes itís dirty again with our wet weather in Belgium. :-(
    I did put a layer of Chemical Guys Black and Chemical Guys XXX Hardcore wax on it after I washed it. The exhaust tips also got some CG Metal Polish and a layer of CG Metal Wax.















    The next updates will probably be something with a bit of carbon fiber... ;-)

    So I made a quick edit of a couple of clips. I checked the sound with my laptop, Beats by Dre in-ears and Sennheiser headphones.

    Laptop didn't sound indentical. The in-ears and headphones gave an almost identical exhaust note.

    For all you guys waiting on the performance upgrades... The new ECU will be arriving any day now. And we will be trying different sizes of intercooler cores this Saturday! I will also be discussing the production of a small amount of intercoolers (like 10 intercoolers) if people are interested. No need to PM or reply here. I will make a seperate group buy thread.

    That 190d is just simply fantastic. I'd be smitten to have one over on this side of the pond.
