Porsche 911 Modified

The vehicle in detail

HCC is proud to present “Whiskey”: A 1974 Porsche 911S, finished in Copper Brown Metallic and built in the spirit of a Carrera RS–inspired hot rod using period-correct components and specifications from an era when these parts could still be sourced directly.

Power comes from a 2.7-liter air-cooled flat-six built to RS-style specification. The engine features Euro pistons with an 8.5:1 compression ratio, Nikasil cylinders, WebCam camshafts reground to 901/01 specifications, RS-spec cylinder heads with 36mm intake ports, and Weber 40 IDTP carburetors. A 1966 aluminum engine case was used for the build and updated with modified oil squirters, machining for 90mm cylinders, and 930-style chain tensioners. Ignition is handled by a period Bosch distributor, and exhaust exits through an M&K muffler with dual-outlet capability. Power is sent through a 915 manual transmission.

The interior reflects the car’s lightweight, motorsport-focused character with RSR-style bucket seats trimmed in corduroy inserts, an original Blaupunkt radio, and front and rear dash mats. Externally, the car is also fitted with an original factory Carrera RS 2.7 ducktail. The car rides on 16” Fuchs wheels and braking has been upgraded with 930-spec brakes.

This 911’s history is equally compelling. Originally purchased new in 1974 from Northwood Porsche in San Antonio by a private jet builder, it was sold less than a year later to a San Antonio-based doctor who owned the car from 1975 until 2012. During his long-term ownership, he carried out the engine work to bring the car to RS-style specification. The car later passed to another San Antonio enthusiast who maintained it diligently, before being acquired by the most recent owner in March 2025.

Whiskey is offered with a Clean Texas Title, and full documentation since it’s first day off the production line.
