roots

Ok, so I bought a 2001 Saleen that has a series 4 blower on it. I want to go twin turbo is the only reason why I want to get rid of it. I have an 04 cobra so I hear plenty of whine from the KB on it, I want to try something different. I'm asking 2500 obo.

A friend just bought an '02 Lincoln Blackwood, and he wants to put a roots blower on it. Is there a factory setup (cobra, Lightning, GT500) that will bolt on to the Blackwood/Navigator engine?
