I just found a good deal on a D2. Is this to big.

 

Procharger hasn't made a D2 in a long while. From what little I remember it was a fairly mean blower capable of supporting near F2 cfm specs. So yes it would likely be too big for what you are trying to do. I'd look for something more modern anyway as I doubt procharger still makes repair parts for that thing. What are your power goals? If under 550, you could probably find a nice p1sc for under 1500 bux. If you'd like to be between 550 and 750 a d1sc would fit the bill and you could likely find one of those used for less than 1800.
