Ferrari 328 GTB Parts & Accessories

The Ferrari 328 GTB represented the refined culmination of Ferrari's mid-engine 308 platform lineage, arriving in 1985 with a bored-and-stroked 3.2-liter version of the Tipo F105 V8 that produced approximately 270 horsepower along with updated aerodynamic bodywork penned by Pininfarina. The GTB berlinetta variant offers more structural rigidity than the open-top GTS and remains highly valued by drivers who prioritize road course performance and open-road touring over open-air motoring. Owners maintaining or restoring a 328 GTB need parts that are specific to the 3.2-liter engine specification and the revised body panels, which differ from the 308 in both fitment and engineering detail. The 328 GTB occupies a sweet spot in classic Ferrari ownership combining relative parts availability, strong performance, and the timeless Pininfarina styling that age exceptionally well.

Popular Upgrades

Timing belt replacement kits including the water pump, tensioner, and cam cover gaskets are the most critical service items for the 328 GTB's Tipo F105 V8, with belt failure causing catastrophic interference damage. Bosch Motronic 2.5 fuel injection components including fuel pressure regulators, throttle position sensors, and injector rebuild kits keep the electronic injection system performing at factory specification. Suspension bushings, Bilstein or Koni shock absorbers, and wheel bearings are regularly sourced for chassis refreshes, along with brake caliper rebuild kits and Ferodo friction materials for safety-critical work. Body panel clips, rubber seal sets, and exterior trim pieces are sourced for concours restorations and collision repairs on the distinctive Pininfarina bodywork.

Performance and Handling

The 328 GTB chassis uses the same double-wishbone suspension layout as the 308 but with revised geometry calibrated for the higher output 3.2-liter engine and updated tire specifications. The 270-horsepower V8 provides a meaningful step up from the injected 308's 214 horsepower, rewarding drivers who push the car into the upper rev range where the engine's character truly comes alive. Refreshing the suspension with new bushings and properly valved dampers transforms the 328 GTB's handling from the compliant but vague feel of worn components to a crisp, connected experience that matches what Ferrari intended. Correct wheel alignment per factory specs, combined with period-appropriate or modern high-performance tires on the stock 16-inch wheels, unlocks the chassis potential that many 328 GTBs have lost through years of deferred maintenance.

What makes the 328 GTB engine different from the 308?

The 328 V8 displaces 3185cc versus the 308's 2926cc, achieved through a longer 73.6mm stroke combined with the same 83mm bore used in the 308 QV engine. This additional displacement provides stronger mid-range torque that makes the 328 more tractable in everyday driving than the high-revving 308, while the redline of 7700 rpm still rewards drivers who use the full rev range. The Bosch Motronic 2.5 electronic fuel injection system on the 328 replaced the K-Jetronic mechanical injection used on 308 injection models, offering more precise control over fuel delivery and ignition timing across operating conditions.

How often should the timing belt be replaced on a Ferrari 328 GTB?

Ferrari recommends timing belt replacement every three years or 30,000 miles on the 328 GTB, whichever interval arrives first, because the rubber belt compound degrades with age regardless of mileage. The V8 is an interference engine, meaning belt failure causes immediate and severe internal engine damage through valve-to-piston contact. Most specialist workshops recommend combining the timing belt replacement with the water pump, idler pulleys, and cam cover gaskets to avoid unnecessary labor duplication when these related components reach the end of their service life.

Why These Parts Fit Right

Every part in this collection is identified by model year and 328 GTB specification to confirm compatibility with the 3.2-liter engine and berlinetta body configuration. Clear fitment notes differentiate between parts shared with the GTS and items specific to the GTB body structure. Orders ship fast from stocked inventory to keep your service interval or restoration moving forward without delays.
