    Hi guys i've got a mercedes c220 estate which is a 2.1L twin turbo diesel guzzler.

    I wanted to know what kind of stuff i could do to it and what you guys have done to yours in terms of performance. I know there is remaps out there(which ill do via rolling road after the upgrades) and i know that someone will point out that i should have gotten a C63 but unfortunately that wasn't possible.

    standard its 170BHP and 400NM torque.

    So far i've done:
    -Cat-Back twin pipes
    -KN intake
    -Rotors and pads

    I would like about 250bhp+ and anything over 550NM torque so what i was thinking of doing was:
    Uprated Fuel Pump or Larger Injectors
    DPF removal
    EGR removal
    maybe a turbo upgrade/ tuning(boost valves?)

    cheers guys let me know what you think.

    Why fit a bigger intercooler; are you getting problems with heat soak?

    Obviously if you're running a lot more boost than intended, you need more charge cooling, but over-sized intercoolers introduce lag. - Think of the volume between the turbo and the inlet manifold; if you increase that volume, you need to put more air in to get the pressure to the engine (PV=nRT).

    My suggestion would be to crank the boost up. - As long as you don't push it off the current map the ECU will adjust the fuelling for the increased volume of air.

    Hi, I was looking at getting the turbos tuned to higher boost and i think that some people do fit the slightly larger intercooler as they are pretty interchangeable.

    Looking at a 30-40bhp increase via a map at the likes of MSL or PCS

    Money you're planning on spending on this could've just bought a 350 :eek:

    i don't really want to just do a map, i like working on cars and i spend most my pennies on it, and i just want to see what is possible. I wouldn't have gotten insured on a c350 unfortunately.

    Surely with these proposed mods declared, your insurance would go up regardless?

    It's odd isn't it? - I think if you have improved the cars safety, that goes in your favour. However significant power hikes work against you.

    It also depends on your insurer; some won't touch a car that isn't absolutely standard, and some don't seem bothered as long as you declare everything.
