Hi

1) I was looking for GTB2060VKLR for my Alfa 159 1.9JTDM and I found ref numbers for it 802774-5005s and 5007s it is Mercedes GL 350 Year 2011 Turbo.
I found new, and also I found 11-hour-run test turbo from factory. I bought the used one for now, because ıt has still one year guaranty, anyway. But in the Plate
it is only written GTB2060V and last number is 5 not 5005 or 5007, is it normal ?

2) I asked him , for the shaft, it is moving a little bit. My older turbo has 300.000Km and was ok. Also shaft was moving a bit. He says, its ok, because every part which needs to be oiled, need to have some space, is it normal,

3) For the electrical VNT controller, I will figure it out, but do you ever know pin-outs or do you ever control it before?

4) For the space issue, I need to turn the turbo a little bit. But in the intake side, I cannot do it. As you see VNT controller is connected to intake. But exhaust part is free, Do you think I have a chance to losen screws and turn it some degre?

That looks like a journal bearing turbo which will have movement up and down as they float/run on the oil.

Your better off changing to an actuator and still control it with the vacuum.

If you loosen the screws you will be able to clock it and try and give yourself the space you need.

I've taken your numbers from your plate and they all point towards a vklr unit I thought if it was a vklr it would of been printed on the plate but I may be wrong/are wrong

The number should be a vklr unit. But, that number is stamped into the compressor housing.
Check out the oil flanges of the chra. If you look into the oil return hole, you can see the bearing arrangement.

I think I saw it, I cannot take a clear picture, but as I know journal bearings are colored yellow/gold - because of brass like material. But mine was gray like normal ball bearing.

Looks overly complicated... Why don't you use something more simple (classic charge cooler), and just keep all connections between turbo and manifold as short as possible.

You could mount classic charge cooler somewhere by the side of the engine, where battery is mounted and relocate battery to the trunk. That should work just fine.

I got one for an Excort RS turbo and like you say Tribesman, I was intending to mount it under the bonnet, after having moved the battery to the boot, I was also going to cover it in aluminium heat sinks to assist in heat loss, a sort of hybrid intercooler/chargecooler.

Mine is a Pace one, the type thats essentially an air to air intercooler enclosed in a water jacket, the type emre2blue mentioned in his link is supposed to be much more efficient than the type I have.

I didn't want big intercooler in front of my car. Because In Winter sometimes I close in front of the car, So my second project is a controller for flaps infront of the car, managing the air flow.

Hi again. I don't want to open a new thread, Just I learned some dimension about downpipe. And draw it. Can you give me some hint about it?

My Turbo dimensions are :

44.86mm - Downpipe Entrance
39.6mm - Exhaust Manifold Out

51,20mm - Air Inlet From MAF
42.52mm - To intercooler.

So I made a flange, and 45mm to 60mm cone - in 60mm . Bend with 60x1.5 and move a little bit and finish it with 63.5x1.5
