Displacement2977 cc
GearboxClose-ratio
Prova Engineering, a team with extensive NSX racing experience including Le Mans, builds this NA1 to beat GT-Rs on lap time rather than on power. The tuning concentrates on the chassis: the engine is left fully balanced with strengthened cooling and management, while the suspension, brakes, alignment and weight balance carry the car’s pace, with the aim of breaking one minute at Tsukuba.
