There's a way to do the intake swap. I've seen FC's 13BT motors with the upper intake off the 3rd gen before. I dont know about the exhaust. I've got no experience with turbo cars but i would imagine you'd have to use the manifold that fits your turbo. i believe the exhaust ports on the actual block are the same though (should be... it's basically the same engine)
