1980 Porsche 911 SC-L 3.1 Targa
Rare Factory Tuned Prototype for the G Series Cognoscenti - Documented & Authentic.
“Despite being ‘as near perfection as it can be,’ a fair chasm existed between the performance of the SC and its 930 big brother. Seeing an opportunity to bridge the gap, Porsche quietly set to work on the company’s very first ‘factory tuning kit’ intended for road use. Enter Rolf Sprenger and his Department of Special Requests at the Kundenzentrum (Customer Center). Sprenger — the father of Bosch mechanical injection in Porsche’s road cars — would soon make another indelible mark on the 911 lineage with the Flachbau (Flat-nose) 930. However, on this SC-based project, the work of his team flew almost entirely under the radar. Their goal? 210 hp — the same as the revered ’73 Carrera RS”.
This rare 911 variant is virtually unknown among Porsche enthusiasts since an option code never existed officially. Designated as 3.1 SC-Leistungsgesteigert or “increased power” this special package boasted 210 hp at 5,800 rpm and 206 lb-ft torque at 4,700 rpm, achieving 0-60 in a claimed 6.5 seconds with a top speed of 143 mph. Production figures are uncertain, but an estimated 150 units were delivered to Porsche preferred customers, mostly in Germany.
Sprenger’s team took the stock 930/03 engine seen in RoW SCs (930/09 for MY1980) and bored it from 95.0 to 97.0 mm, the same as the 3.3 Turbo motor. This yielded 3122 cc with the stock 70.4-mm stroke. The compression ratio was increased from 8.6:1 to 9.5:1, which necessitated the use of premium grade fuel (98 RON). An upgraded fuel distributor was employed, while pistons and cylinders were sourced from Mahle. To handle any additional cooling needs, a larger oil cooler — likely left over from the racing program and similar to the eventual 3.2’s unit — was mounted in the right front fender. Finally, a taller fifth gear of 0.759:1 (rather than 0.785:1) pushed top speed higher. In the Kundenzentrum, technician Elmar Willrett assembled the engines under the supervision of master engine mechanic Helmut Pietsch.
Chassis No. 31826 may well be the only example in the US and it was the subject of a feature article in Porsche Excellence Magazine on December 2009.
Speedart Motorsports is delighted to offer for your consideration this Zuffenhausen rarity that has been part of an esteemed collection and curated at the highest standards – the matching numbers Targa is presented in exceptional condition throughout, fastidiously maintained and on the button.
We welcome all serious inquiries while extending an invitation to all interested parties in order to witness up-close and personal this G series Special. The sale of the motorcar is accompanied by the Porsche Certificate of Authenticity, owners manuals, service booklet and tool kit & jack. Furthermore, the all original interior is complemented by the Porsche Classic Communication Radio (PCCM) combining the analog past with digital connectivity for timeless driving pleasure.
