Long time follower, first time poster. Forgive me for ignorance. One of the most informative sights I have seen. Anyone in the know or have educated guesses as to why no DI in this motor. Scott?? The N54 uses it. Word is P-cars are soon going to employ this technology to their high strung power plants. BMW talks about efficiency with this motor. Is there any hope for E46 M3 type mpg?
