What do you mean by outed?
I think Mazda is coming out with a Twin turbo V6 version for the speed6, supposed to produce somewhere around the 350-380hp range.
I worked at Mazda and was told the twin turbos were going to be a diesel and only make 200 HP or so but have a ton of torque, I don't remember the exact number.. They also said Mazda is getting rid of Mazdaspeed and focusing more on better fuel economy because of the market. This was back in Feb. though, maybe they changed their plans?
