the two systems and the destination of the two vehicles: the Delta HF was designed for sport driving, the Prisma for all-conditions safe driving. Engines As on the Delta, the SOHC engines were derived from the Fiat Ritmo, revised by Lancia engineers with a Weber twin-choke carburettor, a new inlet manifold, exhaust system and ignition. On Fiat engines Lancia make their own aluminium heads and fuel injection systems, only some parts of Fiat can be used for restoration of Lancia i.e. engines.
