Hey all....Just wondering if anyone has ever swapped from a 2v to the 4v before and what all needs to be changed. Recently came across an awesome 4v and a buddy may help me drop it in. My car, a 96 Mustang GT, is pretty much stock and I was wondering if I'll need to change my Kmember, transmission, or any other parts, or if it will just drop in. I know I'll need to retune, or get a new computer, but I'm just concerned with the bigger parts. Can someone help me out and give a little input....Any help would be much appreciated! Thanks guys.
