--Guards Red with Black leather interior, Black carpeting, 3.4 Liter Air cooled 6-cylinder Turbocharged engine, RUF 5-speed manual transmission, Matching Numbers, Sunroof delete, RUF registry documented conversion per RUF Factory letter noting RUF BTR II numbers. The BTR marked the beginning of RUF as a manufacturer in its own right, establishing itself as the most highly regarded of all the Porsche tuning companies. The BTR was inspired by the FIA Group B regulations of the time, utilizing a 930 Turbo as a basis to compete with the fastest products from Ferrari, Lamborghini and Porsche itself. The BTR was routinely regarded as the fastest accelerating road car at the time. The BTR utilized a 930 turbo engine bored to 3.4 liters and then fitted with Mahle pistons, RUF 935-type camshafts, RUF intercooler and a larger KKK turbo. This resulted in a power output of 374 bhp. Various other modifications to the car included enhancements to the body and interior, RUF sport steering wheel, RUF gauges, RUF suspension, RUF specific 17-inch wheels, RUF front spoiler with oil-cooler, Fog lights, RUF quad-pipe sport muffler, and a RUF five-speed gearbox. Upgraded to RUF BTR II Specification by the Official RUF Importer for Switzerland in 1992. Originally delivered as a 1979 Porsche 911 Turbo, this Guards Red example was upgraded in June 1992 by Elite Sportwagen, the official RUF importer for Switzerland to full RUF BTR 3.4-liter specification, supported by period invoices and factory documentation. The conversion included rebuilding the original 3.3-liter flat-six to 3.4-liter BTR II specification, allocating a RUF BTR engine number, replacing the original four-speed transmission with the RUF five-speed manual transmission with limited-slip differential as well as further enhancements. Those enhancements include, RUF carpeting, Updated instrumentation, a RUF steering wheel, Racing harness seat belts, Revised front valance with oil cooler, RUF signature four-pipe exhaust, RUF 17" Speedline wheels, RUF CTR braking system with manually adjustable brake-bias control, a hallmark of the period BTR/CTR program, Bilstein coil-over suspension, RUF Anti-Roll Bars, RUF front upper strut brace, Porsche RS type sport seats as well as a Matter rollbar as used by Porsche Motorsport. The BTR engine upgrade as per RUF's dyno records confirms the newly built BTR II engine delivering 402.5 PS (approximately 397 bhp) at 5,800 rpm and 1.0 bar of boost. A factory letter from 1999, signed by Alois Ruf, confirms the car?s configuration with its BTR motor, CTR-derived braking system, and distinctive four-pipe exhaust. From 1992 to 1997, the BTR II was maintained annually by the Swiss RUF importer. Through the late 1990s and early 2000s, it continued to receive regular Porsche dealer servicing, before entering a period of light use with periodic maintenance. In April 2024, the car returned to RUF Automobile GmbH in Pfaffenhausen for an extensive engine-out overhaul with invoices on file totaling over 20,000.00. This RUF BTR II is accompanied by its original maintenance book, invoices, and correspondence showing limited use since its RUF upgrades as well as its most recent RUF GmbH service-overhaul. This BTR II stands as one of the most well-documented examples of RUF?s legendary BTR II performance conversions.
