A.J.D. Sim spent some time in the Middle East and picked up the word, “Yimkin” which means “maybe” in Arabic – he established Yimkin Engineering in May, 1959 to specialise in development and tuning works…
…in September, 1960 Motor Sport magazine reported the fairly numerous successes in Club races of the Yimkin Special snd also noted the basic design as being suitable for the Formula Junior race category. Also, although other engines could be installed, the original Yimkin Special used an in-line A-series engine. So, the advent of the ADO16 with its transversely mounted A-series engine put Yimkin in the position of being able to offer, “Enlivened Performance Conversions” for the ADO16.
There were two stages of tuning for both the Austin/Morris 1100 and the MG 1100.
