In Drag by fullboost

Tim Roads’ Datsun 1200 is proving the smaller capacity 12A rotary engine isn’t dead yet. Huge thanks to #BecauseRacecar for supplying this video.

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 28×9 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.
