1988 Porsche 911 Targa Diamond Anniversary Edition

This 1988 Targa needs some love, it is being sold with no engine no transmission and no dme/dme harness.  Otherwise it is as pictured.

It is equipped with its correct 15 Inch rims, rear spoiler and Signature seats.  The interior is showing its age, dash has some cracks, seats have a lot of sun damage.  The front and rear body seams are all original and it shows no signs of of any prior accidents, the right rear has a small bump by the tail light area, it has had some repainting in its life, the top is in good condition.  The targa suffered some storm water damages and has a branded title of salvage.

Our research of the few of these special models we have owned indicates Color was “697 Diamond Blue Metallic” (Peter Morgan calls it Marine Blue in his book) with color coded 15″ Fuchs wheels of which our targa has its matching Fuchs in 15 Inch.

  • Silver blue “ruffle” finish leather seats with Ferry Porsche signature on headrests
  • Silver blue silk velour carpet in coupe as well as under front hood
  • Short shift
  • Anniversary dash plaque (round and placed on the glove compartment lid) was found on some cars but ours does not have one.
  • Some cars had front spoiler and rear wing (code 473), some did not, and some cars had the Carrera logo, some didn’t (code 498).
  • 250 cars stayed in Germany
  • 300 went to the US
  • 325 for R.O.W. (50 RHD for the UK)

Porsche produced 80 of these in Targa form 1 of which is the targa we are offering.


The Silver Anniversary cars, on the other hand, have a turbo-center console, full leather, grey leather seats with black piping, plush carpet throughout and in trunk, and color-matched Fuchs. There were reportedly only 500 made – 300 coupes and 200 cabs.

The replacement for the SC series came in 1984 as the 911 3.2 Carrera, reviving the Carrera name for the first time since 1977. This was the last iteration in the original 911 series, with all subsequent models featuring new body styling and new brake, electronic, and suspension technologies.

A new higher-displacement motor, a 3.2-litre horizontally opposed flat 6-cylinder, was utilized. At the time Porsche claimed it was 80% new.[17] The new swept volume of 3164 cc was achieved using the 95 mm (3.7 in) bore (from the previous SC model) combined with the 1978 Turbo 3.3 crankshaft’s 74.4 mm (2.9 in) stroke. In addition, higher domed pistons increased the compression ratio from 9.8 to 10.3:1 (9.5:1 for the US market). New inlet manifold and exhaust systems were fitted. The 915 transmission was carried over from the SC series for the first three model years. In 1987, the Carrera got a new five-speed gearbox sourced from Getrag, model number G50 with proven BorgWarnersynchronizers. This slightly heavier version also featured a hydraulically operated clutch.

With the new engine, power was increased to 207 bhp (154 kW; 210 PS) (at 5900 rpm) for North American-delivered cars and to 231 bhp (172 kW; 234 PS) (at 5900 rpm) for most other markets. This version of the 911 accelerated 0–60 mph (0–97 km/h) in 5.4 seconds and had a top speed of 150 mph (240 km/h) as measured by Autocar. Factory times were more modest: 0–60 mph time of 6.3 seconds for the US version and 6.1 seconds for cars outside the American market.

The brake discs were increased in size to aid in more effective heat dissipation and improved oil-fed chain tensioners were fitted to the engine. To improve oil cooling, a finned cooler replaced the serpentine lines in the front passenger fender well. This was further improved in 1987, with the addition of a thermostatically controlled fan.

Driving refinement and motor reliability were improved with an upgrade of the fuel and ignition control components to an L-Jetronic with Bosch Motronics 2 DME (Digital Motor Electronics system). An improvement in fuel-efficiency was due to the DME providing a petrol cut-off on the overrun. Changes in the fuel map and chip programming from October 1986 further improved the power to 217 bhp (162 kW; 220 PS) (at 5900 rpm) for North American delivered cars as well as for other markets mandating low emissions, like Germany.

Three basic models were available – coupé, targa and cabriolet. The Carrera is almost indistinguishable from the SC with the external clue being the front fog lights that were integrated into the front valance. Only cosmetic changes were made during the production of the Carrera, with a redesigned dash featuring larger air conditioning vents appearing in 1986.

In 1984, Porsche also introduced the M491 option. Officially called the Supersport in the UK, it was commonly known as the “Turbo-look”. It was a style that resembled the Porsche 930 Turbo with wide wheel arches and the distinctive “tea tray” tail. It featured the stiffer turbo suspension and the superior turbo braking system as well as the wider turbo wheels. Sales of the Supersport were high for its first two years in the United States because the desirable 930 was not available.

In 1988, Porsche produced 875 examples of the CE or Commemorative Edition 911 Carrera in coupe, targa and cabriolet variants to mark the production of the 250,000th 911. Distinguishing features include special diamond blue metallic paint with color-matched Fuchs wheels, front and rear spoilers, and interior carpets and leather. These cars also featured Dr. Ferdinand Porsche’s signature embroidered on the seats in the headrest area. Of the 875 examples produced, only 300 were imported to the US (120 coupes, 100 cabrios and 80 Targas), 250 were sold in Germany, 50 went to the UK, and the remainder to other countries.
