blower = supercharger. I'm talking about before and after the air is compressed. The air comes into the throttle body and into the blower. This is before. After it goes through the blower and into the lower intake, it'll be at higher pressure. This is after.
The vac lines should be the same, the only change you'll need to make is on the BBV. Normally there's a line going from the FPR to the BBV solenoid, you need to eliminate.
