The Opel Kadett D was also built in South Africa by General Motors South African (Pty) Ltd. The South African range was made up of four-door fastback sedans, five-door hatchbacks, and a five-door estate model called the Voyage.[19] The engines used are Opel's 1.2 litre overhead valve inline-four (L models only), or the OHC 1.3 liter (GL, GLS, and Voyage). Power is 60 PS (44 kW) and 75 PS (55 kW) respectively.[19] Later a 1.6 liter was added and also a 1.8 in the GTE performance model.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).[8]
