Q for tech - difference between 128i and 130i

Hi there. This came up in another thread, and I'd really like to know the answer.

According to the info I've dug up on the Intenets, it seems that the European 130i hatchback and the American 128i coupe both have the same engine (N52B30). But the 130i is spec'ed at 190kW/262HP while the 128i is spec'ed at 172kW/230HP. My question is: what is done differently in the 130i to generate the additional HP? (And, more importantly, how might it be possible to re-create those gains on the U.S. version of the engine)?

Thanks in advance.

That makes two of us! Actually, the latest European versions of 125i/325i/525i also carry the very same engine (of 2996 cm3), yet in this version rated at a measly 215 (US) HP ;-).

It would be nice if there were some BMW factory bolt-ons that could do it, or better yet a re-flash. Still if there was a way to bump up +20 HP for under $1,000 as is claimed here for the 325i, that would be rockin'.
