you also need his intake manifold to do the bolt up...its going to get pricey, you need the pulley assembly for the belt section. go to stangnet and find out if the intake man from the 03 cobra can fit the 4.6 seeing that it comes from a 5.4l. Their should be an aftermarket manifold you could buy to bolt that up and start boosting, since you already have the supercharger thats the costly parts already out the way... couple thousand you should be able to bolt that sucker up. have fun and good luck
