A new upgraded engine was commissioned from John Rasenberg, the idea being to prioritize torque and drivability. John wanted t try some new ideas and the results exceeded expectations. Giving approximately 150bhp, but with a very fat torque curve in a light coupe body, the GT Junior was now a roadburner.
In keeping with its sleeper status, the gearbox was rebuilt to cope and by now the decision had been made to keep the car looking as factory as possible, even retaining its 1300cc badging. A Nardi steering wheel together with Alfaholics column extender improved both the ergonomics and look and feel of the interior, and a final touch was a set of GTA style wheels, unusually finished in the style of 1970s magnesium wheels.
