Engine specifications
One page per engine: every position named, filled from the catalog where a part exists, and left explicitly empty where none does. Prices total per currency and are never converted; nothing is estimated to make a total look complete.

911 (993)
The ideal 993 engine
A specification for the strongest air-cooled flat six the 993 can carry, assembled from parts that exist — and honest about the ones that do not.
30 positions · 26 filled from the catalog · 1 with nothing catalogued · 24 factory drawings

911 Turbo (997.2)
The ideal 997.2 Turbo engine
The first 911 Turbo without a Mezger engine, specified with the six-speed manual — which removes the ceiling everyone complains about and moves it somewhere else.

Why two pages look so different
The 993 specification replaces almost everything, because reaching a modern standard on a 1995 air-cooled engine means buying four valves per cylinder, a forged crankshaft and standalone management. The 997.2 Turbo specification barely touches the engine, because Porsche had already forged the rotating assembly and fitted direct injection and variable-geometry turbochargers. Specified with the six-speed manual it also sheds the PDK, which is the component tuners name when they explain why they stop. Putting the two pages side by side is the clearest way to see what fifteen years of development actually bought — and what it quietly took away.
