PORSCHE 930 TURBO , Show condition , 15.300 miles , Euro spec , 300HP , extensive history and services from new -

The original Turbo had an arrangement lifted direct from the 2.7-litre Carrera but this latest 930 was enhanced with 917-derived cross-drilled and ventilated discs with aluminium hubs and finned four piston alloy calipers. Disc diameter was up from 282.5mm to 304mm at the front and from 290mm to 309mm at the rear. Disc thickness was also increased.

Right-hand drive 911 Turbos were finally fitted with the Hydrovac brake servo that had been present on left-hand drive examples since late 1976.

Forged light alloy wheels were supplied by Fuchs. 16 x 7-inch rims were fitted at the front and 16 x 8s at the rear. Dunlop or Pirelli tyres were usually issued.

The only cosmetic change made to these 3.3-litre Turbos was a new rear spoiler which was positioned on a boxier housing to accommodate the bulky air-to-air intercooler. The main body of the spoiler was also reconfigured. It now featured a flattened top with myriad cooling vents and a thicker rubber surround than before.

That no other visual updates were deemed necessary was a testament to the 911’s classic good looks.

The same was true inside. By this time the half leather seats with tartan fabric centres and matching door panels were seen less and less as full leather upholstery generally took over.

The familiar five gauge instrument binnacle featured a central tachometer with integrated boost indicator flanked to the right by a speedometer and clock. To the left were combined pressure / temperature / level gauges for the oil and fuel.

Standard equipment included electric windows, a four-speaker stereo with front wing-mounted electric antenna, a rear wiper, headlight washers and front fog lights.

Customers could optionally specify a ZF limited-slip differential, rear fog lights, air-conditioning, a sunroof and central console.

Compared to the outgoing variant the 3.3-litre Turbo was 7mph faster (161mph) and 0.6 of a second quicker from 0-62mph (5.1 seconds).

As usual tighter safety and emissions legislation in the USA meant those cars sent across the Atlantic came with several modifications.

All 930 motors were fitted with an air pump to reduce exhaust emissions regardless of destination, however, the ‘49 US-state’ Type 930/61 engine additionally came with thermal reactors while California-bound Turbos used Type 930/63 units further burdened by a vacuum control.

Output of both versions was down from 300bhp to 265bhp at an unchanged 5500rpm. The torque rating was also slightly lower: 291lb-ft instead of 303lb-ft at an unchanged 4000rpm.

Cosmetic changes to these US-spec. derivatives included amber running lights, red rear indicators and body coloured headlight shrouds. Weight was unaffected but performance figures were slightly inferior.

Production of the 3.3-litre 930 began in September 1977 for the 1978 model year. Still only available as a Coupe, 1757 were built on the K-series platform.

The 1979 model year L-series followed in September 1978. All cars now came with the extended centre console as standard and chequered Pascha upholstery was added to the options list. US-bound 930s were uprated with air-conditioning at no cost. In total 2552 were completed.

Instead of 1980 model year 911s adopting the expected M-series moniker Porsche started from scratch to reflect a new 17 instead of 10-digit chassis numbering system. These latest A-series 930s came with dual instead of single exhausts and a brass tube oil cooler.

Further developments were introduced for the 1984 model year E-series 930. Changes included a brake wear indicator on the dash, a three-speed heater, new interior upholstery with Porsche script and revised pressure-fed timing chain tensioners.

Only 881 were assembled, the lowest figure for any full year of production.
