I am assuming with 42# injectors and a supercharger that you have a custom tuned chip. You should be able to eliminate all that purge crap and walk around it all in the tune.

But ya brake booster, fpr, gauge, and pvc is right. But if you still have A/C your gonna need to get vacuum to that line coming out where the evap is otherwise your only going to have air coming out of the defroster vents and not the panel vents.

And I would go with using the pvc from the manifold (factory set up) and see what happens first. With a solid motor and only 12 psi of boost you really shoulnt have a problem. But then again I have been wrong before and I am not affraid to admit that.
