I have no idea how many Ks, it feels good and it does not seem to be passing any oil. I bought it as part of an engine package off Dyson about 3 months ago and they promissed me that it was in perfect condition. I have not used it my self as I am getting a much bigger turbo for my setup. This turbo is the best model that comes on any of the rotary's. My mate is getting 210kw@ the wheels with one of these turbos bolted on to it.
