The FIA-compliant GT3-spec Nismo GT-R made its debut at France's Magny-Cours last August, and now Nissan has announced global availability for teams and privateers.
Power for the new racer is provided by a track-toughened version of the twin-turbo 3.8 litre V6 that drives the roadgoing GT-R, producing the same 390kW and 612Nm delivered by the 2011 model.
FIA restrictions keep the racer from producing the same (or more) 405kW and 632Nm of the updated 2012 production car.
Unlike the 'regular' GT-R, the big six in the racing car is mated to a six-speed semi-automatic racing transmission, and the racer's overall weight is down to 1300kg - slashing around 400kg from the production model.
The Nismo GT-R GT3 gains the usual assortment of enhancements, including a stripped-out interior with roll cage and full racing seats, carbon-fibre everywhere, an overhauled aero kit and wide-open intakes and vents.
