There is also a drifter in Melbourne with a K20A turbo that is internally OEM and that makes 300rwkw all day every day & JDM Yard have seen 400kw on a near stock turbocharged K24, so please explain why you can't make 350kw on a stock K series with enough boost?
Us hp reads roughly 15% higher then aus, regardless circuit racing puts a lot more abuse on motors then street driving.
Also Yonas is running a built motor iirc.
