[The Former PFR]

Sounds like Audi gave that thing a helluva engine. I do wonder how easy the twin turboing will be with direct injection. I am not sure that you can just buy bigger direct injectors, and if you could the price would probably be staggering (not that a lambo buyer would necessarily care). I suppose you could add normal injectors, but assuming they designed the runners without wet flow in mind, that could lead to other problems. In addition, depending on how much boost it run, it could really mess with the direct injector's ability to spray cleanly, or the amount it is supposed to. I guess there are other turbo Direct injection engines out there that people mod, but I am not too familiar with what they do. I know the Diesel guys get around it somehow (obviously), but I don't think they use the same kind of system most gas engines do.
