I just installed the stage one. And there isnt much difference between it and the stage two. The install was pretty straight forward. Saleen includes an install manual they put in a binder. It was very usefull although some of the pics could have been better. Just take your time and triple check every thing. Also, if you dont have an impact wrench.... Get one. IT was the only snag I ran into. Its the only way to loosen and secure the alternator pullies. But other than that, and being worried that I didnt have the water pump control box (no longer used or included ) It was really easy. Good luck and have fun.. I know I am.
Talked to them about the stage three kit today.Thinking of doing the install myself as they are booked up for a while.Didn't sound over the top on difficulty.I guess when you are done all of the skinned knuckles will be worth it!

Can't be any harder then the Whipple install, and Saleen's instructions are pretty good. I'd say tackle her yourself........in the end you will be happy you did.
