There's loads of turbo Pintos in Finland with huge power and many proven low budget recipies too. One of the most common being the use of Saab H-engien rods and VW-mahle pistons. Three different models of turbo Sierras with the Pinto were also converted from new by the importer back in the days. You could get exhaust manifolds from these versions for example. You can try the international section in the forum at
