When the Fiat 126p was exported to Australia, they called it the FSM Niki. This unique Niki spent the last six years being transformed by the owner. The factory straight-twin has given way to a twin-turbo 1.2 L Nissan HR12DE inline-three. The motor features a RB20 throttle body, 1000 cc injectors, and a BorgWarner R2S serial turbocharging system. The combo produces 170 horsepower to the wheels. It is capable of more but the limiting factor is fueling and sensors. The inline-three is paired with a Subaru Impreza transmission built by Subarugears which also includes their adapter plate and flywheel.
