Adrian Szydło from Dziupla Kastoms owns a unique 1993 Fiat 126p. It originally came with a 704 cc flat-twin capable of 26 hp (19 kW) and four-speed manual transaxle. The car is now powered by a 1085 cc flat-twin taken from a BMW R1100RS motorcycle capable of 90 hp (66 kW). Power is sent to the rear wheels by a five-speed manual transaxle from a 1981-1990 Škoda Garde/Rapid (type 743) with a custom flywheel. The car rides low thanks to a pushrod suspension with airbag shocks and stops using Fiat Seicento disc brakes on each corner. STRADALE Classics interviewed Adrian in the video below (Polish).
