    Thank you very much for answering:D
    It has 60000miles on it, 96000kilometres. Is that alot for the supercharger and belt tensioner? Dont think the BPV has been working the last years.
    Motor mounts and lower control arm bushings is in good condition.
    I will do a leak test and compression test.
    When I've done this, wich mods will most common give about 195-200whp?

    Every thing Dave said. I have a 17% pulley and 130,000 on the clock with no problems yet. As long as your car does not live at the red line you should be ok. But with the 17 pulley you are pushing higher temps. I have also heard that it also leans out at red line with the stock injectors if you have a 17% pulley. I don't know if that is correct.

    Engine wise I have a CAI, headers, exhaust, 17% pulley and an ATI crank pully. If you get the ATI pulley stay with the stock size. My next engine mods will be Injectors and eather a GP Intercooler or Meth injection. After this is don I will get a tune.

    You may want to do some suspensions mod first.

    Oh also check the SC for oil leaking out. It only holds a few ounces in the front and back. If it runs dry it's time for a new SC.

    If your interested in meth injection Dave is our local meth head.

    Ok 60k is not that bad but I still would replace the tensioner. I will post up a link for one that is over $100.00 less then the Dealerahip price and is the same unit.

    Tensioner for $85.00 I replace mine about once a year at that price because a slipping belt equals power loss and I am OCD about my cars maintenance.

    You can get 200 WHP EASY with what you have now by just adding 440 cc injectors and a custom DYNO tune from Jan at RMW.

    Link for Jan and his contact info. http://www.revolutionmotorworks.com/?page_id=40

    I will definetly change the belt tensioner as Dave recommends.

    Could you send me a link for the 440cc injectors? :D
    I looked at the Bytetronik full access self tuning kit. Could get 550cc bosh injectors with it for only 275dollars.
    There is a good tuner 2hours away from me, but he did not have the tools to access the MCS ECU, I don´t know about any MINI tuners in all Norway. But with the Bytetronk, he can tune it on a dyno?

    Opinions?

    Ok, thank you :D RMW is the way to go then:D
    I'm going to change the BPV as well, because the spring is broken.
    Do you recommend OEM BPV or DT BPV, the DT BPV is about 100$ expensiver than the OEM one, because of shipping and custom taxes.

    For an 2003 I would go for the DT one over OEM because they did not fix the OEM one until 05, 06 model year.

    Does the 05/06 OEM BPV fit my 2003 MCS? I know the guy on the BMW dealership who order the parts. Maybe he can just get me one from the 05/06 R53 :D

    Ok, I will order the colder range plugs to be sure. The temperature herr is below 0 degrees celsius at winter time, in summer maybe lucky reaching 20 degrees celsius for a week or two :)
