    A remap will get you most of the way there. Just keep in mind that the TD4 doesn't have the steel crank that the BMW version of the M47 gets. The crankshaft is known to fail in standard form, so could well fail faster with more power.

    The main difference is that the lr m47 is the original one that was modified to fit transversely and common rail was added known as the m47r. BMW themselves added there own common rail and made the m47d20tu (circa 150bhp)

    This was revised again towards the end of the e46 lifespan and called the m47d20tu2 I believe this one had closer to 180hp, then it was replaced by the n47d20 in the newer e90s

    Rover/MG did an X-Power upgrade to 131hp for the M47R.

    Ok, so then its best to leave the engine as it is, now when its working good and do I really need the extra power? Will the autobox take more power, dont think so.

    Do we know definitively if a BMW steel crank can be fitted to an M47r ? If so which model car is it from please? I have a vested interest - see my crank broke thread !

    Would be easier to get an engine from a bmw and just put over all the extras?

    I have a Synergy, which boosts the power a bit. I actually only got the synergy, so I could use the cheaper Pierburg MAF.
    The Jatco auto box has a maximum torque limit of 300 Nm. My auto slips if I run the Synergy on the maximum power setting.
    I suspect most this is down to it having covered 120,000 Miles. However 300 Nm isn't very high for a modern turbo diesel, so increasing power must be done with caution.

    Diesel Do was looking into it a while back, although I don't know how he got on, as Muddy Mods was keeping him busy, about the same time he said he was looking into it.
