Editing R33 (section)

=1993=

After the [[R32]] ceased production, the R33 [[:category:Skyline|Skyline]] was introduced in August 1993. Slightly heavier than the [[R32]], and available as a 2 and 4 door, 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 four wheel steering system was previously featured on the [[R32]] [[GT-R]]. It moved the rear wheels via a small electric motor situated on the rear differential instead of being a hydraulic type 4ws unit such as on the [[R32]].

As an option, a 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]] [[:category:Skyline|Skyline]]s.

The [[RB25DE]] and [[RB25DET]] engines also became equipped with [[Nissan]] Variable Cam System (NVCS) on the inlet cam. This should not be confused with VTEC-type cam timing, as NVCS only adjusts the rotation of the cam and does not alter the lift or duration of the valves. NVCS engines can be identified from non-NVCS RB engines by the cam gear cover— the NVCS RB has a bulge on the cam gear cover, at the end of the inlet cam. To celebrate their 40th anniversary, [[Nissan]] introduced a very rare 4 door [[GT-R]]. Two versions of the 4-door [[GT-R]] were avaiable from [[Nissan]]'s subsidiaries: the first was produced by Autech, and the second was a joint Autech/Nismo project.

A wagon based on the R33 platform was released in September 1996, called the Stagea. It had a different body style than the R33 and (with the exception of the RS FOUR variant) was only available with an automatic transmission. This is the only four wheel drive manual transmission [[Nissan]] with the [[RB25DET]] engine. Presumably, a 5 speed 4WD [[:category:Skyline|Skyline]] equipped with an [[RB25DET]] would have been too close in performance to the much more expensive [[GT-R]]. There was also a Stagea releasd with full [[GT-R]] running gear, the [[RB26DETT]] engine, and manual transmission.
