    K26 turbo - 450+ HP - after full rebuild

    I'm selling second generation of modified k26 turbo with cnc matched wheel. First generation was tested on my car. It managed to pull 430HP with 1.5 bar boost peek and 507 Nm limited for stock rods safety.

    This turbo is after full rebuild that includes:
    - new compressor wheel
    - new exhaust wheel
    - cleaning the turbo with very small glass parts
    - changing both bearings (plain and thrust) for higher performance ones
    - changing seals in the turbo
    - changing o-rings
    - changing screws
    - changing deflectors
    - re-profiled compressor cover to match compressor wheel

    Balancing turbo low and hi speed with very high tolerances. Like new

    First gen sizing (cold side):
    inducer 54,50
    exducer 76,70
    tip 76,70 mm

    I have sold two first gen turbos. Now is the time for second generation

    This one has new race blade (cold side):
    inducer 56,50 mm
    exducer 78 mm
    extended tip 81 mm
    same weight as the first gen blade

    That can safety deliver 450 HP and more. On my setup with first gen I had stock 3B head with both 7A cams and it made 430 HP. It is ultimate turbo for stock engine (I recommend not more than ~500NM on stock rods to be safe), much better than RS2 one, with aftermarket exhaust manifold (stock kkk k24 mount on manifold) it can do wonders. It will hold boost up over 7000 rpm when the first gen lost after 6000 rpm.

    Spools very good, there is almost no lag when the turbo is in the revs. I will put the same turbo in my car for track racing in 2015. https://www.facebook.com/AudiS2PL

    Currently I am out of k26 turbos. I might have them in the future but on very non regular basis.

    If you send me turbo the price 700 euro + shipment with GLS express. Sorry the price is fixed.

    This is dyno graph form first gen:

    I'm interested in this... will it fit in stock location using my existing RS2 exhaust manifold and current 3" downpipe?

    Thanks

          Sounds like a bloody good deal! I'm half tempted to pick one up for the future, how many are you planning on making and how long will they be available for Albert?

            Right now I have 2. One for sale. Might sell second one also.

            I can deliver you one with extra Christmas ribbon with the turbo

              What housing did you use for the hotside? No8.

              Is the center oil and water cooled?

                  Can you give me some other specifications on the hotside- turbine wheel, and what housing? Sounds like a very good combination :-) no surge at all?

                    Hotside (turbine wheel) is modified stock k26 wheel. It is custom tuned to enable more flow. No surge.

                      Is the hotside turbine wheel back cut to allow more flow?

                      Is it noticeably laggier to later to boost than an RS2 turbo?

                        This is the graph (below) with first gen compressor wheel, rear is the same first and second gen.

                        It has less lag than RS2 turbo because the rotating mass (grams) is less than RS2 turbo but delivered much more power.

                            Nice curves, I bet that feels good on the road.

                              I am very tempted, however I did promise myself I'd stop at RS2 spec and I'm more than happy with my S2's performance as it is.

                              That graph doesn't half look good though!

                              I will ponder it for another day or so, if I miss out then tough luck to me for being too slow.
