Ferrari 308 GTB Parts & Accessories

The Ferrari 308 GTB introduced a new era for mid-engine Ferrari sports cars in 1975, bringing fiberglass and later steel bodywork over a tubular steel chassis with a 3.0-liter transverse V8 that quickly became one of the brand's most beloved platforms. Owners and enthusiasts maintaining or restoring these cars need parts calibrated to the GTB's specific berlinetta body and engine configuration, which evolved significantly across production years as Ferrari transitioned from fiberglass to steel bodies, added fuel injection, and updated chassis components. Sourcing correct parts requires knowing the production year, whether the car is a carbureted or Bosch K-Jetronic-injected variant, and the specific body generation. The 308 GTB remains one of the most accessible classic Ferrari ownership experiences, and well-sourced parts keep these cars on the road and on track at vintage events.

Popular Upgrades

Fuel system components including Bosch injector rebuild kits and fuel pressure regulators are critical for 308 GTBi models running the Bosch K-Jetronic system, while Weber 40 DCNF carburetor rebuild kits address the earlier carbureted cars. Timing belts, water pump assemblies, and cam cover gaskets form the core of any major service interval on the Tipo F106 V8 engine. Suspension components including Koni shock absorbers, control arm bushings, and wheel bearings restore the handling precision this platform is capable of. Brake hardware from Brembo-compatible suppliers and Ferodo friction materials keep stopping distances in check for track events and spirited road use.

Performance and Handling

The 308 GTB chassis uses double-wishbone suspension at all four corners mounted to the tubular steel frame, which provides excellent geometric control under cornering loads. Refreshing worn bushings and dampers on these cars makes a dramatic difference in steering feel and turn-in response, since the original rubber components typically degrade significantly after forty years. The transverse mid-mounted V8 placement keeps the polar moment of inertia low, contributing to the quick directional changes that made the 308 GTB a natural candidate for both road courses and the Targa Florio-style mountain events it contested in period racing. Upgrading to stiffer polyurethane bushings and rebuilt Bilstein or Koni dampers transforms the handling from vague to precise for drivers who push the car on track days.

What is the timing belt service interval for a Ferrari 308 GTB?

Ferrari specifies a timing belt replacement interval of three years or 30,000 miles for the 308 GTB, whichever comes first, due to the rubber compound degradation that occurs even in low-mileage cars with age. Failure to replace the timing belt on schedule risks catastrophic engine damage because the 308 V8 is an interference engine where valve-to-piston contact occurs if the belt breaks. Most 308 specialists recommend replacing the water pump, cam cover seals, and tensioner at the same service interval to avoid reopening the engine for related failures shortly after.

What is the difference between the 308 GTB carbureted and fuel-injected variants?

Early 308 GTB models used four Weber 40 DCNF carburetors to feed the V8, producing approximately 255 horsepower and offering a raw, responsive throttle feel that enthusiasts often prefer for road driving. The 308 GTBi introduced in 1980 replaced the carburetors with Bosch K-Jetronic fuel injection to meet emissions regulations, which reduced power to approximately 214 horsepower but improved drivability and cold-start reliability. Many owners of injected cars source intake manifold and carburetor conversion components to restore the original power output and the characteristic induction sound the carbureted engine produces.

Why These Parts Fit Right

Every part in this collection is cataloged by model year and engine variant to help 308 GTB owners confirm compatibility before ordering. Detailed fitment notes distinguish between fiberglass-body early cars, steel-body later models, and the GTBi injection variant. Orders ship fast from available inventory so your service or restoration project stays on schedule.
