The marine specific blowers have different impeller blades designed for better efficiency at lower boost levels (5-10psi). I worked with Jim Summers from Procharger about 5yrs ago testing their units on the dyno. Also...the nomenclature is slightly different (M2 sized same as D1) and so on...
There are a variety of tubing suppliers. For aluminum we like the Vibrant Performance stuff. Super nice and polished. If a natural or your not worried about some "marks" in the tubing we usually source them from Raceparts Solutions or any aircraft tubing supplier.
