Big Six Turbo
BMW called M30 engines as "Big Six" (M20, just like mine is "Little Six"). This page is about an M30B34 turbo engine, originally in a 745i from 1985.
It's not a weak car even it's stock form (3.5 Turbo, automatic, see pic),
but this engine is now in a light chassis (e30):
Here I try to put together what's needed to GenBoard it
