L6 3.4 240Z - The Green Hornet

L34 engine

It’s not hard to see that Greg Scott has a stirring passion for his 240Z. Theirs has been a long-term love affair. Fully committed to the spirit of the Z, Greg has been on a 17+ year journey of constantly improving all aspects including brakes and suspension while steadfastly resisting all temptations of different engines, forced induction or fuel injection for his beloved 240Z – widely known as the “The Green Hornet”.

The LZ is an interesting concoction from Nissan in that it was a custom-built twin cam, 4-valve head with a narrow valve angle, atop a modified L18B bottom end. Camshafts are driven by a chain of 7 gears and 3 sprockets with a short chain at the top, and all this hardware produced a characteristic rattle at low revs in the rally version, due to high lift valves but conservative timing. At first experience this rattle was rather disconcerting but became endearing to the many fans who followed the golden era of Australian rallying in which this engine played a staring role.
