I second this recommendation.

Robert @ Rotary Shack has a lot of knowledge with turbos and blow-thru set-ups.

I am running a Jay-Tech manifold with a Holley 650 and it works great. I also have a stand alone injector system in the hard piping for high end rpm's and boost. All I know is that this setup is easier and cheaper than EFI....Hands down! The only problem that I have run into is getting a carb that will hod up to my 30 lbs. of boost. Its going to cost me $550 to get mine sealed so if anyone knows of a cheaper place do tell.
