Since production of the last GT-R had ceased 16 years earlier, Nissan needed a new vehicle to compete in Group A racing.
Due to the rules of Group A, all participating vehicles must be existing road cars. Enter the 1990 Nissan Skyline R32 GT-R.
The 1990 model R32 was released with a new motor designated RB26DETT. The RB26DETT is a 2.6 Liter, DOHC, 24 valve,
in-line 6. It uses a six-throttle inlet manifold, has a bore of 86mm and stroke of 73.77mm which results in a total
displacement of 2569cc. A compression ratio of 8.5:1, twin T28 Garrett turbochargers and a large front-mount
intercooler help the RB26DETT produce a rated 280hp at 6800rpm and 260ft-lb of torque at 4400rpm. In most peoples'
opinion, the R32 was underrated by the factory.
The R32 GT-R uses a 5-speed manual gearbox which is connected to Nissans ATTESA-ETS (Advanced Total Traction Engineering
System for All - Electronic Torque Split) all-wheel drive system. ATTESSA monitors the car's movements a 100 times per
second, including wheel rotation, and lateral as well as longitudinal acceleration. When wheel slip is detected, the
system electronically distributes torque from this spinning wheel to one without slip. Torque distribution can be
adjusted to settings between 0:100 and 50:50. The rear of the R32 utilizes an active Limited Slip Differential.
The GT-R uses a multilink suspension, front and rear, and steering is further improved by utilizing an all-wheel-steering
system (Super HICAS). Super HICAS allows the GT-R's rear wheels to steer a maximum of one degree, based upon the car's
current movement and the angle of the steering wheel input via the driver. This results in a more nimble feel and is
handled via electric actuators and computer controls.
The V-Spec (Victory Specification) uses a stiffer suspension and a revised all-wheel-drive system. Performance is further
improved by using larger 225/50/17 tires and 324mm back/300mm front Brembo ventilated disc brakes.
Exterior dimensions are: 4545mm length, 1755mm width, 1355mm height. From a visual perspective, the GT-R is similar in
appearance to the other R-32 models with some exceptions. The GT-R includes front-bumper air inlets, larger intercooler,
a taller rear wing, aluminum front wheel arches and bonnet, and GT-R (and V-Spec if applicable) emblems.
Interior changes include the addition of race seats, the turbo boost gauge and digital clock were removed from inside
the instrument cluster and replaced with a front wheel torque meter. The clock has been relocated to the left of the
steering wheel into the instrument surround. Finally, oil temp/voltage/turbo boost gauges were added beneath the climate
The R32 GT-R notched up a whopping 29 straight victories out of 29 races. The GT-R proceeded win the JTC Group A series
championship 4 years in a row, thus earning the name "Godzilla".
