Manifold and turbo i would keep it simple with a standard frs manifold and turbo.they fit spot on in the mk2 bay and the decat pipe fits spot on with a blacktop sump setup with no chopping to the crossmember like on some mk2 turbo conversions and the turbo is nice and lag free so will make it a quick car.i would go rs1800 inlet (ho) and either get injectors to suit or convert it to top feed ones.
