I am sure, a tuner will do the engine swap....If a M5 V10 can fit in a 3series, they will certainly find a way to put a 4.4 v8 twin turbo in it
It's gonna take even longer than 10 years before it makes its way to a 3 series. If anything, the horsepower wars will have to come to an end eventually, what with gas prices and global issues, and BMW will probably just stick to modifying their inline 6.
