I know nothing about the turbo upgrade but have you experienced any issues while running vta?
 
I think it depends more on realistic goals you have. If you're only looking to go a bit further, say 330-350, I'd imagine the GT2871 is fine. Which is what I'm looking at.
 
Not trying to thread jack here but what do you have blocking the recirc line, the only thing ive seen is the plug that is sold on SU's site.
 
GTX3071 is a great option. It'll make 400whp+ easily, but still spool really quick, relatively.

Make sure you do injector seals.
