Ferrari F106B V8 Engine with 5-Speed Transaxle – 2.9L Fuel-Injected – Ferrari 308 GTSi

This Ferrari F106B 2.9-liter V8 engine with attached five-speed manual transaxle was recently removed from a 1980 Ferrari 308 GTSi by the seller and is offered as a complete drivetrain assembly. The engine retains its factory fuel injection and ignition components, and videos of the engine running are provided, offering valuable confirmation of operational condition prior to removal.

The F106B represents Ferrari’s transition from carbureted V8s to fuel-injected grand touring powerplants, delivering improved drivability and reliability while maintaining the high-revving character that defines classic Ferrari V8s. This engine is paired with the correct rear-mounted five-speed manual transaxle, which remains attached and features the desirable dogleg shift pattern used across Ferrari’s late-1970s and early-1980s mid-engine models.

Ferrari produced variants of the F106B between 1980 and 1982 for use in the 308 GTBi, 308 GTSi, and Ferrari Mondial, making this drivetrain highly suitable for original replacement, restoration projects, or period-correct conversions.
