HKS HYPER SILVIA
Perhaps the most famous S15 of all, the HKS Hyper Silvia S15, piloted by Nobuteru Taniguchi won the first event of the 2002 D1GP season at Ebisu Circuit, finishing the year with an overall second place. It would later become a backup car to the newly built RS2 in 2003, which would see ‘Nob’ rank fourth overall for the season.
Both versions featured seam-welded chassis, with items such as the radiator and oil cooler rearmounted in pursuit of a 50/50 weight distribution. Interchangeable weights were used to balance the car to the track on which it would compete.
The SR20 featured the newly released HKS 2.2-litre kit and HKS GT2835, with SPL intake and exhaust manifolds, new HKS 256/264-degree camshafts and HKS reinforced valve springs, HKS 740cc injectors, dual HKS fuel pumps, and the package managed by an HKS F-Con V Pro. It produced 358kW, delivered through an HKS fivespeed sequential box and Nismo GT LSD. And, for suspension, the factory arms were replaced with Nismo and Ikeya Formula examples with a set of HKS Hipermax coilovers, while Endless six-pot fronts and R33 rears took care of braking.
