1967 912 Coupe Modified

The Polo flat-four engine was the brainchild of Dean Polopolus, founder of Polo Motors, who envisioned a lightweight, compact four-cylinder version of Porsche’s iconic flat-six. The concept, essentially a shortened 911 engine, had reportedly been explored by the Porsche factory but never formally developed. Dean made it a reality by cutting a 911 crankcase, removing the center cylinders, and welding the halves back together. Today, Polopolus offers the engine as a complete build or, selectively, in kit form. Buyers receive a custom-cast crankcase along with a crankshaft and cams from Web Cam, then complete the build using standard 911 parts. The result is a high-revving, air-cooled engine with classic Porsche character in a lighter, more compact package.

This 1967 912 Coupe features a 2.4-liter “Polo” flat-four built by Dean Polopolus and installed in 2012. The engine uses a custom cast case, 993 twin-plug heads, billet cams, and individual throttle bodies with an Electromotive ECU. Originally finished in Bahama Yellow, the car includes subtle exterior modifications like a custom decklid with integrated spoiler and LED running lights. Inside, re-trimmed bucket seats feature plaid inserts and “100 Jahre Ferry Porsche” embroidered backrests. Overall, a very nice and well-sorted example of an early 912 with serious mechanical upgrades.

Over the past twelve months, SWB 912 Coupes have averaged $56,300, with a low of $6,500 for a project and a high of $100,912 for a 25-year-family-owned survivor. Given the caliber of work in this build, I expected it to at least challenge that top result—but it did more than that, selling at a final bid of $125,356.
