CTOR - The Cavalier Turbo Owners Register

The Car

The Cavalier 2.0 Turbo 4x4 arrived in Vauxhalls showrooms in October of 1992 replacing the Cavalier GSi. Indeed the Turbo was essentially a GSi 2000 4x4 with the 1993 Cavalier facelift and a turbocharger. The pics below show a standard GSi2000 and a Turbo respectively.


The car uses the same basic C20XE engine fitted to its GSi predecessor but with the addition of a KKK-16 turbocharger. This pairing combined with the Bosch M2.7 Motronic engine management system equates to an engine that produces 204PS (150kW) with 206.5lbf/ft (280Nm) of torque from the factory.


A Getrag six-speed F-28 is the gearbox of choice and is capable of coping with up to 280lbf/ft of torque making it more than qualified to handle the output from the C20LET engine.

A similar semi-permanent 4wd system to that of the GSi 4x4 was also fitted to the Turbo. It uses a transfer box to send the drive from the engine to the rear axle via a viscous coupling arrangement. The viscous coupling allows the drive between the front and rear wheels to vary according to the road conditions and how the car is being driven. Under normal driving conditions approximately a quarter of the drive will be sent to the rear end, however, this can vary up to 100% front or very nearly 100% back.

The system is also semi-permanent in that it will switch itself off when the cars brakes are applied above 16mph. The theory being that this will put the car in Fwd and make the handling more predictable when cornering at speed. The transfer box has its own separate 4x4 ECU which monitors the system and dictates whether or not the 4wd should be engaged or disengaged. To find out more about the 4x4 ECU click here.

The rear differential is the same as used in a 4-litre Holden Commodore and (like the gearbox) is easily capable of handling the power output from the engine.


The car arrived in the showrooms wearing the already familiar GSi body-kit and 16" fan-style alloy wheels bolted to 5-stud hubs. It sported the standard 1993 facelift headlights and grill as well as a colour-coded rear panel and smoked rear lights that are unique to the Turbo.


Leather was an option at the time of the cars release and remained so up until March 1993 when it became a lower-cost delete option. This is why it is more common to find the early K-plate cars with grey or anthracite Albany cloth interior. The thumbnail on the left shows the Albany cloth interior in grey while the thumbnail on the right shows the more commonly found leather interior.

Model Alterations

Along with leather becoming a delete option, in March 1993 a drivers airbag was fitted. However, headlamp washers and the adjustable steering column were removed from the spec list.

As of August 1993 Passengers airbags were fitted and the speedo was now electronically driven by the ABS system as opposed to being mechanically driven. The instrument dials were revised, the 4x4 ECU was changed and the previously weak front lower arms were replaced with stronger versions.

This is largely how the car remained until it was deleted. The youngest cars have an 'Ecotec' spark plug cover, the engine is still the C20LET though (see thumbnails below). A few also came fitted with the Blaupunkt CD300 CD player.
