If I go from a stock intake manifold to lets say a Greddy Manifold with that change the type of injectors I use or fuel rail? Do I need a new fuel rail if I use the Greddy Manifold?

Fuel rail is fine. You'll make some slight alterations to some of the coolant hoses, either run a q45 tb or an adapter for the stock tb, and of course new cold pipe.

You have to alter the fuel rail feed line a little bit, but nothing 20 seconds with a hack saw couldn't handle. I also redid my injector harness so it was out of sight, but I'm anal.

Nice setup! I would have one-upped you and painted my fuel rail to match my valve covers, but I figure I will be selling it for a custom built rail and top-feeds next winter anyways.
