    Owners of the fifth generation Toyota Supra are thrilled about that car

    Toyota Supra MKIV

    In July 1993, the fourth and so far last generation of the Supra came on the market. Internationally, this type is called " Supra MKIV ".

    Toyota Supra MKIII

    In early 1986, the third generation of the Supra was introduced. It is also the first that has not been marketed with the suffix Celica.

    Celica Supra (MK2)

    The second generation was presented in the fall of 1981 and had a completely independent drive with the new (170 hp) 6-cylinder engines.

    2000GT & Supra MK1

    The first Supra built from spring 1978 to summer 1981 was still offered as a top version of the Celica first in Japan and later in the United States.

    Hi guys :blush:

    after 3 times in 1 year that I have been caught by the police with the NurSpec...I am starting of beeing sick about swiss laws.....

    either I am keeping the stock exhaust with a randomtech downpipe and highflow cat OR a guy from honda experience (Patsch with the crazy white S2K :wink: ) told me that R-S-K Tech in Neuenhof were doing full custom exhaust WITH MFK :sunglasses: :grinning: at least for Honda S2K, ATR, CTR....
    So last week I have sent them a mail here is the answer I got:

    Dear Sir,

    Sorry about my english:

    Thank you for your e-mail. Its possible to install a exhaust pipe for your
    car. The diameter of de system is 76mm. The end exhaust tip can be
    determined by you. The complet price for installation is Fr. 1820.-- inkl.
    MWST.

    looking forward hearing from you
    yours sincerely

    Maybe 76mm piping is not enough for single Supras but for BPU it should be ok, I think the NurSpec is 3 inches wich is, I think, 78mm.

    I have just sent an another email to be sure it will have MFK, I'll keep you updated...

    What do youguys think about it?


    :grinning: :wink:

    I think I would be the next to take one, if it really has MFK!

    Hmm it sounds pretty good considering that 3 Inches are 76mm (76.2 when i remember right).

    This could be a real alternative to the NurSpec, but I first need to thear a Soundsample. :grinning:

    € 1163.68. Aber Tüv-Gutachten wird nicht reichen.

    We need a paper with all the datas about CO emissions and noise done in a Mkiv (with all the serial numbers of the car and exhaust).

    Sorry but I don't understand Krümmer :rotwerd: :grinning:

    I just phone to the guys from R-S-K-Tech GmbH.
    I'll take a look at their shop this week. I want them to convert my open external wastegate into a closed system. Neuenhof is only about 20 Min. away.
    I'll also ask the guys about the NÜR Spec R. Perhaps they could modify the NÜR Spec so we could pass the MFK without any problem.

    Ich habe gerade mit den Jungs von der R-S-K-Tech GmbH telefoniert.
    Ich werde diese Woche bei ihnen in Neuenhof vorbeischauen, da ich das offene Wastegate in ein geschlossenes umwandeln will.
    Neuenhof ist nur etwa 20 Min. von hier entfernt. Ich werde auch gleich betreffend Auspuffanlage etwas auskundschaften. Eventuell gibt es ja eine Möglichkeit, die NÜR Spec R so anzupassen, dass sie MFK-konform wird.

    I was there yesterday and talked to the guys.

    We defined the following 4 steps:

    Step 1:
    I will bring my Supra on the 5. September and they will reroute the external wastegate pipe back into the downpipe.

    Step 2:
    We modify the intake system. They will bend a 4" Intake pipe so we can reroute the pipe into the original intake system. After all we optimize the original system for better airflow.

    Step 3: (Also interessting for others)
    We do a noise measure and after that they are able to say it's possible or not to modify the Blitz NUR Spec R midpipe so I can pass the MFK/TÜV. (Or at least the exhaust system is more quiete.) This would be greate and much cheaper than manufacture a new exhaust.

    Step 4:
    Convert the open Blow off system into a close. (recirculation)

    next Steps "to be defined......"

    Looks great :grinning:

    Keep us update.....

    Thank you very much SpeedUp :sunglasses:

    :wink:


    P.S: I just saw the mail from RSK about the MFK of the complete exhaust

    Dear Sir,

    Yes, you will get a MFK paper. We will need about 2 or 3 days for the
    installation.

    Best regards

    Mit freundlichen Grüssen
