Here we have for sale a desirable Mini GTS from the first year of production, 1973.
Matching numbers original 12H-GTS 1275 engine and twin HS2 SU carbs
A running, driving car that is ready for immediate use but in the medium/longer term will require minor attention to bring it up to the next level. It was repainted some years ago and whilst is mostly very solid and rust free due to being an inland province car, will require minor attention to the sill areas.
One for the Mini enthusiast/collector looking for something a bit different
The Leyland Mini GTS is a unique South African model which was produced in small quantities between 1973 and 1979 as a higher performance successor to the Mini 1275 GT at the Blackheath plant in Cape Town. The GTS has several unique features which make it a particularly desirable model in the Mini range, although awareness of this model in markets outside of South Africa remains limited.
At the time the GTS was built, local content regulations significantly influenced manufacturing in the South African automotive industry. Hence the decision to locally cast a version of the Cooper S engine for use in the GTS was a major benefit to the car, considering that by 1973 the Cooper S specification 1275cc unit had been phased out in other international markets.
The GTS received a 1275cc engine of very similar specification to the Cooper S. The block was locally cast in South Africa by Gearings Foundry in Epping, Cape Town - using the British-spec MK2 Cooper S engine as a template. Coupled with Twin HS2 SU carbs gave 74bhp.
Like the Cooper S, the GTS engine was an 11-stud unit, had integral side covers and the head received double valve springs. The head had an inlet valve diameter of 35.65mm, and an exhaust valve diameter of 29.37mm. The block was bored to the same specifications as the Cooper S, with a 70.64mm bore, and a stroke of 81.33mm to achieve the 1275cc. The compression ratio was also 9.75:1. Unique to the South African engines, however, was the location of the oil filter gallery, which meant the oil filter was fitted above the starter motor.
