History
In 1973-74 Opel worked with Michael May's Turbo-May firm in Hechingen on a KKK turbocharger kit for the 1.9-litre CIH engine of the US "lowlead" Manta. Only two cars were delivered to the press for testing, and about ten are said to have been built at May, chiefly for Opel engineers. There was no official price or brochure, and no May Turbo Manta is known in private hands.
