These bad-boy turbos are designed for large displacement motors that put out serious horsepower. Think: 1,850 to 2,900 horsepower (1,380-2,163 kW) per turbo exceeding 40 PSI (2.76 bar) boost.

The 911 Turbo is truly the stuff of legend, offering genuine supercar performance in a compact and practical package. In its early versions it was also infamous for its unforgiving handling.
