Riviera Sports & Prestige are delighted to present this exceptional 2005 '54' Porsche 911 (997.1) Carrera S Coupe, a particularly desirable example of one of the most sought-after modern-era 911s, distinguished by its increasingly desirable manual gearbox and, most importantly, a recent, comprehensive Hartech engine rebuild. With 71,566 miles, finished in metallic Arctic Silver and paired with a black leather interior, this Carrera S combines timeless Porsche styling with a significant investment in its long-term mechanical integrity. At the heart of this 911 lies the iconic 3.8 litre naturally aspirated flat six engine, producing 350 horsepower and delivering the unmistakable character that makes the 997.1 Carrera S so appealing. Paired with the highly desirable six-speed manual transmission, it offers the engaging, analogue driving experience that enthusiasts continue to seek, with 0–62 mph dispatched in just 4.8 seconds. What truly distinguishes this example, however, is its recent engine rebuild by Hartech, one of the UK's recognised Porsche engine specialists. Addressing one of the most widely discussed concerns associated with the M97 3.8-litre engine, the rebuild included the installation of six new high-strength aluminium-alloy, nickel-silicon-plated closed-deck wet cylinder liners, providing a comprehensive solution to the potential for cylinder bore scoring. This was far more than a superficial overhaul, with the engine stripped and prepared for reassembly before being rebuilt with a new performance piston set and piston rings, new performance crankshaft main and big-end bearings, new thrust bearings, a new timing chain set and guide rails, and a new intermediate shaft bearing. The cylinder heads also received an overhaul, including decarbonising, valve re-lapping, skimming and reassembly with new valve stem oil seals. Further work included a new air/oil separator, new engine mounts, a lower-temperature thermostat, new spark plugs and replacement ancillary components, hoses, oil catch tanks and associated fixings where required. The engine was subsequently refitted, recommissioned with fresh fluids, the air conditioning recharged and the car tested. The scale of this work represents a significant investment in the car's mechanical condition, addressing a key consideration for prospective 997.1 Carrera S buyers while providing renewed confidence in enjoying its naturally aspirated flat six as intended. Combined with the increasingly sought after manual gearbox, it makes this a particularly interesting example for the discerning Porsche enthusiast. The specification is equally appealing, combining desirable factory options with enhancements that complement the car's character. Highlights include optional 19 inch Carrera Classic alloy wheels with full colour Porsche crest wheel centres, PCM Navigation Module, Telephone Module for PCM, six-disc CD autochanger, leather sports seats and a leather dashboard. The sliding and tilting sunroof is another welcome addition, particularly during summer driving, allowing even more of the naturally aspirated flat-six soundtrack into the cabin. Further enhancing this experience is the stainless-steel exhaust upgrade, which adds to the aural character of the engine while complementing the fundamental appeal of this classic Carrera S. With mileage of 71,566 and an extensive service history, this Porsche has clearly benefited from careful maintenance, with the recent Hartech engine rebuild representing a particularly important investment. Presented in immaculate order, both cosmetically and mechanically, it combines the timeless appeal of the 997.1 generation with the attraction of a manual transmission and substantial specialist engine work already completed. For the enthusiast seeking a beautifully presented, naturally aspirated Porsche 911, with a desirable specification and a comprehensive engine rebuild addressing one of the model's principal mechanical concerns, this is an ex
