After this episode, we’re pretty sure we need Sean to narrate everything we do from now on. Everything. Anyway, that S50 out of the oooooold and tired donor BMW M3 (that turned into the Knuckle Busters 1 car) is going into Sean’s E30, but it really could use a refresh. And that’s exactly what it’s getting. Along with making some more room in the engine bay for those extra two cylinders… and maaaaybe some boost, too.
