First S55 Swapped BMW E30 M3
Don't tell the purists, but a few college kids with no car experience just built the first S55-swapped BMW E30 M3 ever. For the layperson, that means the relatively rare first generation of one of BMW's most-loved cars, the M3, now has the twin-turbo inline-six introduced in the 2014 M3 and M4. That's a 400+ horsepower game-changer compared to the stock four-cylinder, and a new era for modded BMWs.
