How much are main stealers charging at the moment ? And is the price new or exchange ?

Do you reckon if we got a group buy together we could maybe get that price down a bit more!?!'93 S4 Avant now back on the road complete with new shiny go faster bits.

Old thread, but anyway: I dismantled the damaged compressor wheel off my RS2 turbo and it had normal thread, not left handed. The rest of the turbo seems ok, no end play and very small amount of radial play in the axle it has done 90000kms (mostly "normal driving" with max boost 1,6Bar) after a complete refurbishing.
I was thinking about betting a fresh comp wheel, or if possible even a K27 wheel to convert it to a K26/27 #6 turbo. But can i reuse the nut and will the turbo need a rebalancing after I put it together? Furthermore where can I get the K27 wheel and housing? Or am I better off binning it and order a Comp Turbo/Garret BB?Leif-Helge

That´s a very interesting question and I also would appreciate any info about it. I managed to put my hands in a new K27 from a 964 turbo. Can I use the hot housing of the RS2 turbo and cold from the K27? I suppose I´ll need to balance the whole thing, isn´t it?

Oh, old but interesting threed.
Thoose cracks in the exhause-turbine seems to coems as standard.
I bought one rs2 turbo in bad condition, Melett didnt want to sell to me because i dont have any balacning machine, wtf?!
Is there anyone at the forum that sells parts or know a cheap shop?
I dont know what the parts name is in english, some kind of bearing is broken in 3 parts and the oil sleve is messed up.

The turbohouse is from a k26 as i understod, the exhausehouse a #6 and the turbine is some special for rs2. Cant recognice the size from any other k-serie turbos.
Do you know where i can buy those parts cheap?Vroom vroom

Now before everyone starts ordering bits up, please think about it!
Whilst I hope I have shown that a turbocharger is a relatively simple piece of engineering, unless you have a known undamaged turbo that you wanted to freshen up, there would be little point in attempting a rebuild. Any mechanical damage would need the attention of a specialist. At the very least you would need very accurate measuring equipment, better than I have really. I can only measure down to 1/100ths of a mm.
The problem lies in the way turbos are rebuilt. In order to recover the various components they are machined. So centre housings are bored larger which means they need greater o/d bearings. Shafts are machined undersize which means that bearings with a smaller i/d are used. It's possible that the grooves that the piston rings sit in have been machined as well and there are different size seals to accomodate that too! I have measured as accurately as possible and by a process of elimination been able to work out that I am on std sizes. This was only possible through the patience of the guy at Melett who gave me the relevant dimensions. In fact I need to revise the shaft diameter. I had rather hurriedly measured it at 9.94mm when in fact it was 9.96mm!
I was starting with a known good hotside. That is to say it was undamaged and was not leaking any oil into the turbine housing. Likewise the coldside form the RS2 showed no sign of lekage (unlike the hotside!). I had been patiently waiting for a good RS2 coldside to become available. So thats why I am attempting this. All I needed from the RS2 turbo was the compressor housing, wheel and seal plate. Although interestingly, I have noticed a slight difference in the centre housings. I explain later!
Wouldn't you want a K26 rebuild kit if it's got a K26 WC center section?
