"The need to reduce fuel consumption along with stricter emission laws had become one of the automotive industry´s most urgent issues in the 1970s. To adapt to these new standards, Porsche reduced its normally aspirated 3.0 litre flat six to 180 hp. Apart from the expensive Turbo, this opened a gap in the model range as customers who desired more power now had to go for the comfortable 928.
Consequently, the 911 SCR conversion´s centerpiece is the SC engine enlarged to 3,185 cm³ with a peak power of 215 bhp at 6,000 rpm. The RUF five-speed manual transmission contributes to significantly improved fuel efficiency. Along with better tractability, the SCR´s road performance nearly matches the Turbo and perfectly closes the gap Porsche left open for political reasons.
Introduced in 1978, the 911 SCR, together with the RUF Turbo 3.3, completed Ruf´s model range of optimized conversions of both the Carrera and Turbo.
Technical: (this was in a table, so I reformatted it)
Power Output (DIN) 158 kW (215 bhp)
at Engine Speed 6,000 rpm

Engine:
* Air cooled horizontally opposed 6-cylinder
* Longitudinally rear mounted
* Chain driven OHC per cylinder bank
* Mechanical Bosch K-Jetronic fuel injection system
* Bore x Stroke of 98.0 mm x 70.4 mm
* Eight main bearing crankshaft
* Dry sump lubrication system
* Electric fuel pump
Transmission:
* Rear wheel drive
* RUF five speed manual
* Single plate dry clutch
* Limited-slip differential, 80%
Performance:
* Top speed of 255 km/h
* 0 - 100 km/h in 5.7 sec
* 0 - 200 km/h in 23.7 sec"
