This is a 94-97 kit, complete p600b kit everything inclued. I have 2 pullies to go with it 6lb and a 12lb. All piping inclued i just bought the real clamps for all the piping, the clamps are the kind you'll find on a powerstroke truck, they cost me a little over $100 but at least you won't have to worry about the piping blowing off. intercooler still like new no leaks. The head unit itself was just rebuilt less than 500 miles on it. I'm looking to gegt $1800 for it complete ready to bolt on. This sure beats the hell out of refilling a bottle everyother week.
