    Hi MBCLUB-

    Looking to modify the engine to get more acceleration performance.

    Apart from a remap, can anyone recommend modifications to the Diesel engine ?
    Such as the bypass of exhaust gas recirculation EGS?
    Possibly larger turbo but rather lower costing part etc.

    Engine: Merc cdi 2.7 engine block: M612 R5 0M612

    Anyone else have any experience
    Appreciate any input.

    My engine, (same as yours) is running 242bhp from 163bhp standard and 730nm of torque from 370nm standard,
    Lots and lots can be done with this engine,

    BOYT, sounds good.
    ohhhh very nice! have you got a pic of the intake pipe.
    are the fuel rail module chip boxes any good or just rubbish?
    Im tempted to put a larger turbo in, ideally off a larger merc cdi, how easy is it- just dont want fault codes to pop up?

    thanks,

    All will really need custom coding on the ecu,
    The 320cdi turbo is a strait bolt on swap apart from a adapter required, keep away from the box's, there pure **** just tricking the ecu, you can't beat a good quality remap! Not a cheap remap! To many slave tuners doing poor quality remaps for 150 quid, you get what you pay for on remaps

    I'd be interested to know about a possible turbocharger upgrade as well. Would like to see some images of adapter required.

    DDDOOOMMM, I am in the South West of England, where abouts are you? I'm south Devon.
