Oh wait, this isn't the Toyota forums...
Not trying to be a troll but thinking realistically if someone put the time and effort into doing this in the first place, we might have had a 600-700 WHP 335i by now. This effort would surely have taken less than 4 years and created a simpler system as used in every other motor with great amounts of power.
I understand the advantages of DI are great (fuel efficiency, easy and quick power) but as of the current time being (2011, there is only so far that DI can get you, all Mazdaspeed3 and GTI's are in essence tied down by a complicated fueling system as is this platform. Evo's, Supra's and GTR's, dont seem to have any of these problems..... any connection to DI?
Btw, I did have a 335i and absolutely loved it for its ability to incorporate speed, class, and an amazing ability to DD. But in no way was the N54 built to be a drag racer 600-700 hp machine.

Easier said then done as Ive said this myself.
But then it entails a whole new tuning solution and crack at the DME.
I think DI is over-hyped marketing with its "responsiveness, and fuel efficiency, etc"
