it wont just bolt on but where there is a will there is a way
many have made the supercharger from the 03/04 cobra work on their 3.8L and some on the 4.0 I believe so it is possible. The issue you are going to run into is cooling and clearance. The hood may not work and the stock setups are cooled by water, you REALLY REALLY need this or some type of cooling. A standard air/air intercooler will not work due to the compression is right on top of the motor. The only other alternative rather than a water/air heat exchanger cooling solution is methanol and thats just a band aid to me at least.
