I have a 2001 Cobra that has a pretty good baseline of modifications from solid rear axle to aftermarket pistons and heads. I want to make a hair over 1000whp with the car using the 4.6 engine in it. I have a pretty good idea of what I need but I'd like to hear what worked and didnt work for you guys. It has the Windsor block so I do need to change that. My over plan is to use a nitrous kit I have for the car and eventually twin turbos.

JustanotherCobra, go to this link. https://www.americanmuscle.com/high-...ustang-gt.html. Our friends, at American Muscle, have outlined your project. I am now campaigning a 1020 RWHP 1988 mustang fastback. It is built around a Dart 363 with a 86mm turbo. This setup up has been used for the past two years with great consistency. 5.2 in the standing eighth, with only 17 pounds of boost. If you follow this links suggestions, you can build your 4.6l and make some serious steam.
