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, a 930 Turbo was used 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, Stage 3 Motronic injection (rather than original CIS injection) and a larger KKK turbo. This resulted in a power output of 374 bhp at standard boost pressure of .09 bar.

Various enhancements include: RUF sport steering wheel, RUF Seats, RUF gauges, RUF Branded Porsche 917 Derived Brakes, RUF Suspension, RUF specific 17-inch Speedline Wheels, RUF front spoiler, RUF Aero Side View Mirrors, RUF quad-pipe sport muffler, RUF shift Knob, RUF Pedals, RUF five-speed gearbox, Matter roll cage as used by Porsche Racing and a Modern Porsche PCCM head unit-with new speakers.

This particular 930 Turbo has led an incredibly colorful life-lifestyle to date. It was owned in the early 1990's by well-known and respected Porsche collector, Mr. Oscar Velez, Puerto Rico, USA. Mr. Velez, also the owner of Servicio Euromecanico, decided to convert his 930 to RUF BTR specifications. Having contacted RUF Germany, the process began. RUF Germany flew its technicians with all of the necessary parts to Puerto Rico to convert his Oak Green 930 to RUF BTR III specifications. The engine was built to 3.4 liter, the CIS injection removed in favor of RUF Motronic injection which was a system used on the Porsche racing 962's but modified for street purposes. At this time, the cylinder heads were converted to twin-plug for just a bit of extra efficiency. The gearbox installed by the technicians is a RUF Porsche G64 964 5-speed gearbox as labelled by RUF on the casing and as modified internally and externally for fitment to a 930 Turbo of this era. The result is the 930 Turbo RUF BTR Conversion on offer today and well-known as El Hulk due to its exceptional, original Oak Green metallic color and menacing stance.

Kept by Mr. Velez within his Porsche collection for a number of years, this BTR III was subsequently sold to new ownership. It then saw ownership within another couple of Porsche enthusiast collectors. One of which was Mr. Sophocles Zoulas. Mr. Zoulas a long time collector of some of the world finest automobiles, a resident of both Southampton, New York as well as Palm Beach, Florida. Mr. Mr. Zoulas now spending most of his time at his Palm Beach residence felt the RUF BTR was a bit too much for cruising the Palm Beach avenues.

then sold this BTR III to its most recent owner.

For 2025 Monterey car week, we assembled automobiles and owners to enjoy the weeks California car culture and lifestyle. Along with this BTR, we assembled several more of the world's finest automobiles, both vintage and supercars to be enjoyed car week. It was a truly unforgettable time and enjoyed by all.

Since, it has been stored in a climate controlled environment and used sparingly on the road for seasonal enjoyment.

Pure enjoyment as only Porsche and RUF can supply, a RUF BTR is a welcomed addition to any collection of rare-limited production automobiles.

Today, this RUF Porsche BTR III is superb in every respect, service and ready for immediate use.
