    I bet PTG would race it as the E90 M3 won't go into production for awhile.

    Not sure, but the S54 Weighs 326lbs


    .com/engine_faq/][Oops!] Engine data

    146Kg or 326lbs. I would bet the one going into the Z4 M R is going to weigh a bit less than that though.

    Just 326 pounds?

    Dyson's new AER V-8 (twin-turbo) engines that power both of its new Lolas weigh just 250 pounds.

    Yeah, but that engine is very special.

    It is purpose built for racing and nothing else. The M3 S54 engine is a street engine. You could probably take 30 pounds off with just removing the AC components.

    I think the M6 would be too heavy to race

    Where is the link?

    The S54 has an iron-block which adds weight when compared to an aluminum block.

    BMW's M5 Product Information Guide says that the 5.0 liter V-10 weighs 240 kg/529 lbs.

    Re: BMW Unveils Z4 M Coupe Racing Kit

    Hello,
    I still can't find anyone at BMW to provide information on the Z4 coupe Motorsport kit. Would anyone have an e-mail address, contact name or phone number at either BMW Motorsport or BMW who can provide additional sales information.
    Thanks,
    Harold
