Hey now dont count out the NA. There happens to be a 2+2 NA stroked and bored with custom cross flow sports injection intake manifold and Nos and its hitting the 9's in the quarter mile thats very good if you ask me! The car is owned by a customer of escort racing japan. Very fast car. Dont let these guys make you do somthing that you dont want to do. You can do anything you want the resources are out there. It would be much easier to change the motor. If you go with a boost controller vice the stock junk you will save a lot of time with the swap! Use the harness and computer change the fuse panel inside the drivers side kick panel and the harness that runs up the left side under the fender to the front that goes to the fuse box. There will be extra plugs left over after you hook up the motor harness. They are for the boost presure sensors and ect. they dont have to be used. Except for the piping thats about all you have to change to go to turbo!
