50+psi BOOST 12A rotary Datsun | fullBOOST

Tim Roads’ Datsun 1200 is proving the smaller capacity 12A rotary engine isn’t dead yet. The bridge port Mazda still features genuine 12A housing and is fed around 50psi boost by a Precision 76mm turbo. The little ute has dipped into the 7-second zone on a 28x9 pro radial tyre. The car features a G-Force clutchless gearbox and a ladder bar rear end. A MicroTech EFI system is tuned by WA Racing Developments. Its odd stance is due to legacy rules from a racing class known as ozmod, a tyre limited class that originated from our fullBOOST top 10 lists of yesteryear, where standard wheel tubs had to be run to be class legal.
