Nissan Skyline R31 2000 GTSR (1985-1989)

In August 1985 the seventh-generation Skyline "Nissan Skyline R31 2000 GTSR" was launched and was the first to reintroduce the 6-cylinder DOHC engine. Only 800 units were built to allow homologation for Group A Touring Car racing. The ultimate version of the R31 was the RB20DET-R powered HR31 GTS-R Coupe, claimed 210 ps (154 kW), with racing versions making over 430 hp (321 kW) in Group A trim. The R31 GTS-R had a reworked version of the normal RB20DET with a much larger turbocharger on a tubular steel exhaust manifold, as well as a much larger front-mounted intercooler boosting power.
