1989 911 Turbo Coupe RUF BTR Conversion

The RUF BTR, introduced in 1983, was the first car to leave RUF’s Pfaffenhausen workshop as a fully recognized production model with its own chassis number. Based on the Porsche 930, the BTR (short for Gruppe B Turbo RUF) featured a heavily reworked 3.4-liter turbocharged flat-six producing 374 horsepower, achieved through larger pistons, bigger turbochargers, and upgraded intercoolers. Customers could choose either the wide Turbo bodywork or the narrower Carrera 3.2 shell, and RUF complemented the power increase with larger brakes, a revised suspension, lowered ride height, and a freer-flowing exhaust system. Existing Porsche 930 owners could also bring their cars to RUF for a full BTR conversion, making the model accessible as both a turnkey car and an upgrade package.

This 1989 911 Turbo Coupe was originally delivered in Germany and later upgraded to RUF BTR specification by RUF Automobile GmbH. Recently refinished in Black Metallic, it features RUF-specific bodywork including front and rear valances, amber fog lights, drilled door handles, and a signature “tea tray” rear spoiler. The cabin is trimmed in Black leather with Gray piping, RUF-branded floor mats, gauges, and steering wheel. Mechanically, the BTR conversion brought displacement up to 3.4 liters with RUF-specific internals, a larger turbocharger, and upgraded intercooler. Notably, the turbo was replaced by RUF in 2016, and a comprehensive engine rebuild was completed between 2024 and 2025, including a new crankshaft, pistons, and associated components—making this a freshly sorted example of RUF’s iconic 930-based performance flagship.

As you’d expect, comps for BTR builds are few and far between. In the last twelve months we’ve seen just one sale at $140,000, and that same White car has popped up multiple times this year without a deal. That makes this fresh Black Metallic example tough to peg, but with the recent mechanical work and strong visual presentation, I figured it might push past $350,000, maybe even flirt with $400k. But bidders didn’t quite agree, and it stalled at $305,000. Close, but no RUF.
