Porsche 911 Turbo 930 (1975-1989)

“The most famous sports car in the world”
It was in 1963 that Porsche launched the 901 at the IAA in Frankfurt as the successor to the 356 model. It wasn’t long after that thanks to Peugeot who had patented the use of all three digit numbers with a ‘0’ in the middle that Porsche changed their new sports car to the 911 we all know and love today. Originally built only as a Coupé, the 911 had an integral body-frame powered by a new 2.0-litre flat-six engine, which initially delivered 130 hp. A Targa version was introduced in 1967 with a permanently mounted roll-over bar and removable soft top. The 911 was more powerful, bigger and more comfortable than the car it replaced with the air cooled engine rear mounted with an internal lay out being 2+2.

It wasn’t long before Porsche upped the ante by creating the 911S up-rating the flat six engine and using forged alloy pistons. This ensured an increase in power from 130 bhp to 170 bhp, we also see the Fuchs rims for the first time still popular today. By 1972 in order to qualify for sub 3.0 litre GT racing we saw the arrival of a homologation special the Porsche Carrera 2.7 RS arguably the most revered 911 of them all.

The Porsche 911 got wider in the seventies and impact bumpers were soon added along with the 911 Turbo in 1975 with its famous whale-tale rear spoiler and a new 3.0 litre 260 bhp flat six engine rising to 300 bhp in the eighties.

The Porsche 911 still lives on today although the original air-cooled engines were replaced in the nineties by water-cooled versions and as technology advanced so has the 911.

Our buyers guide will focus on the 911 Turbo (930) model starting with the body and chassis. As all 3.3 litre models were galvanised providing they haven’t suffered any disturbances in their rust proofing. Early models of the 930 or in fact any model previously involved in a bump may show signs of rot. Check sills, wheel arches, door skins and the boot floor for the dreaded rust although the 911 is not overly prone to this. Door gaps should be consistent if not this could be signs of repair work as are any leaks into the cabin or boot. Also check the rear wing and its mounting points for any cracks or distortions. The Flat-six engines are solid and reliable with the turbo needing little maintenance compared to other exotic cars, make sure the history is good and it pays to get it inspected by a Porsche specialist. Oil leaks from the cylinder head spell trouble as does smoke from the exhaust.

The four speed box is very durable with synchromesh wear being the only issue, front suspension should not creak if it does this is down to neglect also make sure the history shows regular brake disc replacement as they tend to wear fast. Interiors are good quality as long as cracks and leather hasn’t perished as these are bad signs.  Also checks the heater works well and there is no hint of oil when you give it a blast. A Porsche 911 is a very solid car all round providing it has been well maintained so no history means walk away.

Porsche’s coat of arms is not exactly unique to the company. The company drew inspiration of its logo from the Coat of Arms of Stuttgart, at one time the capital of the Free People’s State of Württemberg. The horse in the logo references Stuttgart’s origin, as the city was built site of a stud farm.

Mark Wilkinson (Managing Partner of Heritage Classic Car Insurance) says

“If there was one car that could represent Porsche through the decades, it would of course be the 911. With excellent performance and that original style which is instantly recognisable the Porsche 911 is the company’s true ambassador and long may it reign.”
