Nissan Skyline R33

The R33 Skyline was introduced in August 1993. Slightly heavier than the R32, it is available in coupe and sedan bodystyles. All models now used a 6-cylinder engine. Nissan took the unusual step of down-grading the GTS model to have only the RB20E, while the twin-cam of the R32 GTS was discontinued along with the 2.0 L turbo RB20DET.

Some models came equipped with a new version of the HICAS 4-wheel steering system called Super HICAS. This computer controlled system was first used on the R32 GTR. Super HICAS used electric actuators to steer the rear, as opposed to the hydraulic HICAS. This generation was no longer considered a "compact" under Japanese legislation that determined the amount of tax liability based on exterior dimensions.

As an option, an active limited slip differential was available instead of the standard viscous LSD. This new unit locked the rear differential if it detected that traction was lost by one of the wheels. A light on the dash also lit up if the LSD engaged. Active LSD came standard on all V-spec R33 GT-R Skylines and was also available on some ECR33 GTS25t models; these can be identified by the A-LSD and SLIP lights on the tachometer.

The RB25DE and RB25DET engines also became equipped with NVCS (variable inlet cam phasing). NVCS equipped RBs have a bulge on the front of the cam cover. To celebrate their 40th anniversary, Nissan introduced a very rare 4 door GT-R. Two versions of the 4-door GT-R were available from Nissan's subsidiaries: the first was produced by Autech, and the second was a joint Autech/Nismo project.

An R33 based wagon was released in September 1996, called the Stagea. It had a different body style than the R33 and R34 and (with the exception of the RS FOUR & Autech variants) was only available with an automatic transmission. A common modification on the Stagea is to fit it with an R34 skyline front, in effect making a 4 door R34 wagon. The Stagea is the only all wheel drive manual transmission Nissan on the R33 platform with the RB25DET engine. Presumably, a 5 speed AWD Skyline equipped with an RB25DET would have been too close in performance to the much more expensive GT-R. There was also an Autech Stagea, the 260RS released with full GT-R running gear, the RB26DETT engine, body kit, 17" BBS style alloys, GT-R instrumentation, and manual transmission.
