I too, had a fox-body mustang. This GN was my wife's dream car. I tried to race a GN with my mustang. I tried to punch it, and whoosh...GN gone!! So I couldn't beat them so...I joined them!!! These are the best cars period. Read up on all websites and go thru your vacuum hoses and tune up. Check if you have a stock chip...if you do, get a Turbo Tweak chip...you won't regret it. Get a boost gauge and a Scanmaster before you start hot-dogging it. When I purchased mine, I found out the hardway by hot-dogging it and melted a piston! Don't think that you'll do nothing extra to your car, because you will!!!
If you purchase bigger turbos and injectors, go as big as you can afford. I upgraded at least 3 times. Have fun and welcome to the Darkside!
