The four Nissan GT-R NISMO GT500s will be the first to trial the first of two engine updates this season at this weekend’s upcoming Sugo GT 300km Race at Sportsland SUGO.
Nissan executive director Toshikazu Tanaka expects the revised NR20A engine to feature “greater reliability, better performance, and to be more competitive” as NISMO, Calsonic Team Impul, Kondo Racing, and MOLA each bid for the GT-R’s first victory of the 2017 season.
The updated 2017 GT-R GT500 has been struggling for power and driveability in the first three rounds of the 2017 season, yet to score a podium so far this season. Their horsepower shortages came to the forefront at this year’s Fuji 500km – a track where Nissan GT-Rs had dominated in the first three years of the current two-litre turbo formula.
Typically, the manufacturers will wait until at least the Suzuka 1000km to use their allotted engine updates – but Tanaka says that the move was precipitated by Lexus’ overwhelming pace at the start of the season, and the teams wishing to make headway in the championships during the Summer Series while the Success Ballast handicaps are at their highest.
Honda and Lexus are expected to bring their first engine updates to Fuji in two weeks’ time for the Fuji GT 300km Race.
