FBX importing into unity doubles or more the amount of vertex's/triangles

Hey All I am importing a geometry mesh which is around 32,000 vertex's however I cant even load it due to the unity 65,000 vertex loading limit, I read that uv seams split the mesh and so do smoothing groups which is a pain in the ass due to the draw call's engorgeing from our old custom engine(420draw calls in XNA, 3600draw calls in unity) Any help will be welcomed!
