For Sale at Auction: 1996 Porsche 911 in Costa Mesa, California

Chassis No. WP0ZZZ99ZTS310764

In 1995, on the heels of the successful 964-platform Carrera RS, Porsche debuted their newest limited-production, lightweight Carrera RS variant on the new Type 993. Fitted behind the rear axle was a Type M64/20 3.8-liter flat-six-a bigger unit than that of any other road-going 993-generation 911-equipped with a strengthened valve drive mechanism and larger intake and exhaust valves. With its cylinder bore increased, the RS produced an additional 28 horsepower over the standard 911. Porsche also equipped the RS with a limited-slip differential and anti-lock brakes sourced from the 911 Turbo. To maximize the impact of these upgrades, weight-saving measures involved removing the hood struts, headliner, interior door handles, power-adjustable seats, and the rear defroster. Lusted after as the purest expression of the final air-cooled 911, the 993-generation Carrera RS was built in only 1,014 examples and limited to the Rest-of-World market, never being sold new in the United States.

Completed in October 1995 and delivered new to the Japanese market through Mizwa, this striking Carrera RS Tribute built on a non-sunroof Carrera Coupe finished in Speed Yellow over a Black partial-leather interior, with air conditioning, and the rare combination of a factory G50/21 gearbox and Varioram induction system. Its transformation into an RS tribute commenced in July 2025 with a comprehensive engine overhaul by Rothsport Racing of Sherwood, Oregon. The M64/20 unit, engine number 1025, was bored to accept 109-mm cylinder spigots and fitted with a Web 528/529 RS hydraulic camshaft set, upgraded cylinder heads with new valve guides and machined sealing surfaces, a 911 Race valve spring set with titanium retainers, Dilivar head studs, ARP rod bolts, and a billet 993/GT3 crankshaft pulley. A custom Varioram M64/20 ECU chip was installed and the engine tuned in on Rothsport's dynamometer, with output rated at 310 horsepower. Finishing touches included Cerakote treatment on the Varioram intake plenum and exhaust components, powder-coated engine tins, and a zinc-plated hardware set throughout. The Rothsport invoice on file totaled $47,455 for the engine work alone.

The drivetrain received equal attention including a rebuilt limited-slip differential, a short-ratio G50/21 six-speed gearbox, a genuine RS lightweight flywheel, a new RS-specification clutch disc and pressure plate, and RS engine mounts. The car rides on Bilstein PSS10 coil-overs, set to RS ride height, and stops via new front and rear brake rotors, high-performance pads front and rear, and a full Teflon/stainless brake hose set. The exterior carries the complete suite of genuine Porsche RS aerodynamic components-spanning the front spoiler, side skirts, and rear spoiler-along with RS-specification Speedline wheels. Inside, a genuine Carrera RS steering wheel and Speed Yellow seat belts are joined by a Rothsport short shifter, while added convenience comes in the form of a Porsche Classic radio with Apple CarPlay and PCCM+ navigation. Air conditioning has been retained and recently recharged, along with a recent oil change in November 2025.

With well over $65,000 invested in the remarkable transformation of this RS tribute, this Speed Yellow 911 is a thoughtfully executed and highly compelling homage to one of the most coveted air-cooled 911 variants. Backed by a 310-horsepower 3.8-liter flat six, a short-ratio six-speed manual, and genuine RS aerodynamics, it offers much of the visual impact and focused character of a 911 Carrera RS in a highly usable package.
