I had 98 GT for the last 11 years and just traded it in and purchased an 07 GT w/44k miles on it. Also just found this site. Anyway there is about a year and half left on the warranty and I was wondering what mods could be done and not void the warranty. Also curious what I could expect the car to run in the 1/4 bone stock. I enjoyed the stock 3.8 in my 98 and had fun messing with the tuner cars. I beat most of them and lost to a few. The blower on the 07 certainly makes this engine more fun. I'll hang up and listen. Thanks.
