It was hard to get Nissan factory racing parts in Australia. The 120Y engine in my sports car had a ported and polished standard head with an angle plane (about 4mm) and reshaped combustion chambers like a Cooper S. 37mm inlet valve, 30mm exhaust. brass valve guides and spacers on the rockers. All threads fitted with stainless steel inserts. 76mm Repco flat top pistons with 1mm chrome moly rings. Approx. 11:1 compression. Dry sump pump on the timing cover driven off the camshaft with a modified oil pump and custom sump with the scavenge pickup at the front. Lightened flywheel with AP racing clutch. 2 X 45 mm DCOE Webbers, Electronic ignition. 1,300rpm idle with an 8,000 rpm redline running on Avgas. Looking at the valve sizes they might have worked an A1400 head to save some work.

The A12 in my Datsun 1200 Coupe was another story. Twin 1 1/2-inch SU carbs, 1mm overbore, balanced, mild cam, extractors and custom exhaust. 160km/h and better economy than standard.
