Never been much into turbos - have you heard about Honda's new direct injection engines? They're typically Honda - more fuel efficient, lower emissions and more power. ;)
It's fascinating because depending on whether the engine is in lean-burn, stoichiometric or high-output mode, the timing of the fuel injection varies. In lean-burn, it's near the end of the compression phase. Up until this engine, the best lean-burns could only go to about 40:1 air/fuel ratio, but this one goes 65:1. ;) In the other two modes, it's during the intake phase, though as I recall even there the timing is somewhat different.
