Yesterday a strange noise appeared after 3000 rpm and up it gets louder, something similar to a loud whistle but with some metal racked, I suppose one of my turbochargers is about to brake. So now the main question is: buy new standard turbochargers, or go for an upgrade. What do you guys think, I don’t want to go higher then 500 hp (now I have 450 hp stage 2 sportec) but I heard (from posts here) that a standard turbo is not reliable on stage 2 cars? As it spins faster than in can. I will be very greatful for any advise. Thanks.

I'd call MRC to get a price on a set of rs6 hybrids , Bigger and better that a standard ko4 but they still fit . good luck . g

Their a four types of a ko4, all made by KKK: standard, 500 ps, 550ps and 600ps. I recently baught the 600ps Ko4.

600ps , whats the damage on a set of those then?

Are you sure that they fit without any modifications ? I heard that the dont fit to a standard RS4. Thanks

Please tell , how much and what is the part number Wimbot.
Have you now got 600?

???

Taymir FYI rs6 hybrids use k04 housings with rs6 internal compressor wheel so they bolt straight in place of k04's

wimbot you have a lot of interest in your post what are these KKK k04 versions, i guessed there should be some like the different k04's on the 1.8t but its never really talked about please more details

did you need to use the rs6 flanges
how much power have they given you

flashyg-
The K04/RS6 hybrids are a direct bolt on for the 2.7t. I would talk to Mihnea at MRC about possible power levels with them.

That is simply not correct.
