It depends on the kit, sometimes if it's just cosmetic recladding of the body the original title is still good.
If it's a replica kit like a FFR Cobra, or Superformance car, or Caterham Super 7 - they are usually titled as the car that they're replicating.
If it's a non doner kit like a locost or something you made up you'll have to see what your state DMV allows.
