no, offically, Lotus has never put a honda engine in the elise (or exgie) from the factory. They came stock with the "Rover K-series" engine, which is not the best performer, and does not pass US emissions. People have swaped in b-series for a while for a few reasons. One is the Honda engines are just better performers then the old K-series. Second, honda engines have already met the US EPA standards, so emission problems are no longer a problem.
