This is brilliant and is basically what I wanted to do. I didn't know Professional Products was selling their manifolds and rails yet--super!
There were three choices I was looking at and none of them are for free:
1) PP manifold (as above) and putting everything else together as time and budget permits. Total price for "everything" $$$$? Guess at $2000-$3000??
2) MassFlo system, totally plug-and-play like the kind that is used on Wayne's R's TTV8 Z car ~$3500 with everything. Pretty sure on that...
3) LT1 (use whole engine, not just efi parts) and use LT1 Edit for software to help with the compatibility for turbo...cost ~$3000-$3500??
Wayne's MassFlo w/turbos:
Xander's Professional Products efi manifold:
Nothing is cheap, but cobbling together stock parts that will work with a turbocharged V8 sounds intriguing, if it can be done with minimal frustration. I understand about the learning curve for EFI, turbos and like if you are a carb guy like me. I suppose the LT1 is the fastest/easiest to install, the MassFlo would run nearly equal with that, while the PP sounds like it would be the most work--getting everything after the fact and putting it all together, hoping that the combination of parts works out. But the satisfaction of making it happen that way...Hmmmm. I'm still thinking about this...
