By now, those who follow know the story:
4B11-maybe similar in design to our engines, maybe not.
This article doesn't go into a real great depth about the engine- it basically is comparing it to the outgoing engine (4G63) used in this line of cars (Evolutions). But, you never know where a gem of info might turn up...
If/when part II turns up, I'll post that link as well
