my car came in two models, one which came turbocharged. i've been having troubles finding a complete gasket set for it, and was wondering if it would be a security issue if i used the head gasket from the set made for the n/a model. the two engines are very identical. and does anyone know where i could find a custom metal headgasket, if i want to turn up the boost im guessing the n/a gaskets won't be reliable
