FERRARI 308 – 328

Ferrari 1975 308- 1989

The Ferrari was made famous by that good-looking detective in Hawaii and numerous Le Mans and F1 victories that made Ferrari a household name. With Magnum P.I. the 308 became famous to every American who wishing they were cruising the streets of gorgeous Hawaii.
The car was always beautiful, fun to drive and reliable when properly maintained.


The Ferrari 308 GTB berlinetta and targa topped 308 GTS are:
V8 mid-engined
2-seater sports cars
They were manufactured by the Italian company Ferrari from 1975 to 1985.
The 308 replaced the Dino 246 GT and GTS in 1975 and was updated as the 328 in 1985.
The similar 208 GTB and GTS were equipped with a smaller initially naturally aspirated, later turbocharged 2-litre engine, and sold mostly in Italy.
The 308 had a tube frame with separate body. The 308 GTB/GTS and GT4 were mechanically similar, and also shared much with the original Dino. Both 308s sit on the same tube platform, however the GT4—being a 2+2—has a longer wheelbase.
The engine was a V8. It was transversely mounted in unit with the transaxle transmission assembly, which was below and to the rear of the engine’s sump.
All models used:
Fully synchromesh 5-speed manual
Clutch-type limited slip differential
Suspension was all-independent with:
Comprising double wishbones
Coaxial coil springs
Hydraulic dampers
Anti-roll bars on both axles
Four wheel vented disc brakes.
Steering was unassisted rack and pinion.
The Ferrari 308 body was designed by Pininfarina’s Leonardo Fioravanti.
The 308 used elements of these shapes to create something very much in contrast with the angular GT4. GTS models featured a removable roof panel with grained satin black finish, which could be stowed in a vinyl cover behind the seats when not in use.

Paris Motor Show 1975
The Pininfarina-styled Ferrari 308 GTB was introduced at the Paris Motor Show in 1975
It was meant as a supplement to the Bertone-shaped 2+2 Dino 308 GT4 and a direct replacement for the 2-seater Dino 246.
Its F106 AB V8 engine was equipped with:
Four twin-choke Weber 40DCNF carburettors
Single coil ignition
European versions produced 255 PS (188 kW; 252 bhp) at 6600 rpm (7700 rpm redline), but American versions were down to 240 PS (177 kW; 237 bhp) at 6,600 rpm due to emissions control devices.
European specification cars also used dry sump lubrication.
Cars destined to the Australian, Japanese and US market were fitted with a conventional wet sump engine from the GT4.
A notable aspect of the early 308 GTB was that, although still built by Carrozzeria Scaglietti, its bodywork was entirely made of glass-reinforced plastic (or GRP), allowing a very light weight of 1,050 kg (2,315 lb).
This lasted until June 1977, when the 308 was switched to steel bodies, resulting in an overall weight increase of approximately 150 kg (331 lb).
Standard wheels were 5-spoke 14-inch alloy. 16-inch wheels were made available later as an option, together with sports exhaust system, high compression pistons and high lift camshaft.

1977 Ferrari Targa 308 GTS

At the 1977 Frankfurt Motor Show the Targa topped 308 GTS was introduced
All GTS used a:
Wet sump engine
Were steel-bodied.
European GTB models retained the dry sump lubrication until 1981.
There were 3219 GTS and 2897 GTB examples made during the 1975–1980 production periods.

Only 808 of the first fibreglass version were made.

In test performances the 308 GTB did 0-100 mph in 15 seconds with a top speed of 159 mph (256 km/h).
Ferrari 308 GTBi/GTSi

In 1980 Bosch K-Jetronic mechanical fuel injection was added on the 308 GTBi and GTSi

Emissions decreased, at the price of a power drop to 214 PS (157 kW; 211 bhp) on European models and to 205 PS (151 kW; 202 bhp) on federalized models.
The Bosch fuel injection system was coupled to a Marelli MED 803A Digiplex electronic ignition system which incorporated a coil, distributor and ignition module for each bank of cylinders.
The car was identical to the 308 GTB/GTS, save for metric sized wheels of a slightly different design, and was fitted with Michelin TRX radial tyres—Michelin XWX on 16-inch wheels were optional.
Inside the clock and oil temperature gauge were moved to the centre console; there were also a new black steering wheel with three perforated spokes, and seats of a different pattern.
494 GTBi and 1743 GTSi were produced before the model was succeeded by the 308 Quattrovalvole in 1982.

1982 Paris Motor Show
Two years later, at the 1982 Paris Motor Show, Ferrari launched the 308 quattrovalvole, in GTB and GTS form.
The main change from the 308 GTBi/GTSi it succeeded were:
The 4-valves per cylinder—hence its name, quattrovalvole, literally “four valves” in Italian—which pushed output back up to 240 hp (179 kW) restoring some of the performance lost to the emission control equipment.
The addition of a slim louvred panel in the front lid to aid radiator exhaust air exit
Power operated mirrors carrying a small enamel Ferrari badge
A redesigned radiator grille with rectangular driving lights on each side,
Rectangular side repeaters.
Interior Updates
The interior also received some minor updates, such as:
Satin black three spoke steering wheel with triangular centre
Cloth seat centres became available as an option to the standard full leather.
It’s other characteristics included:
Metallic paint
Deep front spoiler
Air conditioning
Wider wheels,
16-inch Speedline wheels with Pirelli P7 tyres,
A satin black roof aerofoil (standard on Japanese market models).
The V8 engine was essentially of the same design as that used in the 308 GTSi model.
The gear and final drive ratios were altered to suit the revised characteristics of the four valves per cylinder engine.
One other significant benefit of the QV four valve heads was the replacement of the non-QV models sodium valves which have been known to fail at the joint between the head and the stem.
Bosch K-Jetronic fuel injection and Marelli Digiplex electronic ignition were carried over from the GTBi/GTSi. All US market examples were fitted with catalytic converters

The 288 Ferrari GTO

The 288 GTO introduced in 1984 is considered the first Ferrari supercar.
The 288 borrowed much of the styling from the European 308 GTB QV of the previous year, 1983.
Its features included:
A debored 2.8-litre V8 (but with turbochargers),
Retention of the general bodywork lines
Extended wheelarches,
Different side air vents
Bigger rear spoiler
Longer (5 inch) wheelbase,
Central tubular space-frame chassis.

1985 Ferrari 328

In 1985 Ferrari launched the 328, which replaced the Quattrovalvole.
Between 1982 and 1985 the model was produced in a total of 3042 GTS and only 748 GTB examples
In 1980 Ferrari introduced a two-litre version of the 308, 208 GTB and 208 GTS.
Though mainly for the domestic Italian market, where new cars with engines above 2-litres were subjected to a much higher value added tax. They were also listed in New Zealand.
The 208 GTB/GTS replaced the 208 GT4 2+2. It was regarded as the slowest Ferrari ever made but was surpassed by 208 GT4 Bertone by American magazine Motor Trend In 1980.
The engine was de-bored to 68.8 mm (giving it an undersquare design) for a total displacement of 1,990.64 cc (121 cu in),[10] resulting in one of the smallest V8 engines ever produced.
Fed through four Weber 34 DCNF carburettors, the V8 produced 155 PS (114 kW; 153 bhp) at 6800 rpm. 160 208 GTS and 140 208 GTB cars were produced in 1980 and 1981.

Ferrari GTB/GTS Turbo

In 1982 the two-litre 208 was succeeded by a turbocharged and fuel injected version, the 208 GTS turbo unveiled at the Turin Motor Show. It was the first ever turbocharged road-going Ferrari.
The 208’s engine was given a:
Single KKK turbocharger with wastegate valve,
Bosch K-Jetronic fuel injection
Marelli electronic ignition.
Forced induction increased power to 220 PS (162 kW; 217 bhp) at 7000 rpm. A GTS version was introduced a year later, in 1983.
Interior and Exterior
Both outside and inside the 208 Turbo was almost identical to the contemporary 308 Quattrovalvole.
It could be recognized by:
NACA ducts in front of the rear wheel well openings and “turbo” badging on the tai
Shrouded exhaust pipes
Optional deep front spoiler
Black roof aileron
Production ended in 1985 after 437 GTB turbo and 250 GTS turbo cars were produced,

In 1986 they were replaced by the 328-based, intercooled GTB/GTS Turbo
Regional differences
Among the typically yearly updates to the performance and style of the 308 throughout its run, cars from the same series would have a number of differences between them depending on their intended export market (which is usual for European cars).
For example, a 308 destined for the American market would sport:
Larger heavier bumpers
slightly sturdier frame
This was to meet stringent US Safety Standards.
American market cars also suffered a performance hit due to a compression ratio of 8.6:1 vs 9.2:1 for most of the rest of the world state emissions legislation which reduced horsepower.
As a result of these differences there is often a premium paid for the “purer” European spec car over the federalized car.
Differences between Euro Spec and U.S. Spec Cars
They include:
240 hp vs. 235 hp
Different gear ratios
Lighter, small front bumper that follows the hood line vs. 2.5 mph impact bumper that is extended and has extra “fangs”
Lighter, small rear bumper vs. impact bumper with spacer
Exposed dual tip muffler vs. black muffler cover with catalytic converter
Vitaloni style outside mirrors vs. larger flag mirrors that provide a better view for safety
Small yellow front side marker light with no rear side lights vs. large rectangular yellow front and red rear side marker lights (many euro cars now in the USA had the euro lights converted to USA spec and added the red rear lights)
No “fasten seat belt” warning light in Euro spec
Flash to pass driving lights in front grill in Euro spec
Space saver spare tire vs. full size spare
Rear engine cover top has only a left and right grill vs. “U” shaped grill that provides a larger cooling area necessary for the added catalytic converter just behind the muffler.
Overall weight of Euro spec lower because of door beams and bumpers.
The GTB/GTS has become one of the more recognizable and iconic cars produced by Ferrari to date.
It was made famous on the television series Magnum, P.I.. The series’ lead, Thomas Magnum (Tom Selleck) drove the car around Oahu for 8 seasons while on his investigations, from 1980-1989.
Several 308 GTS cars were used, a new one for each season, most being auctioned off after filming.
The first was a 1979 model with chassis number 28251. In The Cannonball Run movie, a red Ferrari 308 GTS 1979 was used.
Sports Car International
In 2004, Sports Car International named this car number five on the list of Top Sports Cars of the 1970s. The European 308 GTB QV and 308 GTS QV models are considered by many to be the most collectible 308 due to its subtle styling (deep front valance, racing mirrors, short lightweight bumpers) and speed as the fastest of all 308s produced.
