It shouldn't be to hard to put one on the hahn manifold. Another option is to remove the wastegate door and run the external on the exhaust side of the housing. A lot of 4g63 guys run them like this. Some exhaust housings dont allow this so it could effect the turbo you run if you chose to go this route.
