Modern Turbo for 3.6L build...suggestions

Ok. It has taken me 2 years to finally finish building the 94 3.6L motor. We shuffle pinned the case. Used ARP head studs and Rod bolts. Keeping the CIS. Larry at CIS FLOWTECH will upgrade the head for more flow. This will be a 80% street car and 20% track. Mostly running pump gas. Running the S2 factory 4" thick full bay intercooler. Twin scroll headers with T4 flange. Goal is 500-600hp.....Now the big question....
What modern Turbo?
I had a chance to test drive cars at Underground Racing in Charlotte and they only use Preciscion ball bearing Turbos. The owner told me that out of 500 turbos.. they have only had 3 fail. He said that they run very cool and are oil cooled.
Why not use one on our Porsche engines?
They suggested the 6466 7 blade Ball bearing Twin scroll turbo..... A/R can be .84 or 1.0 or 1.15 or 1.32...
Which would be best for our 930's?
What about other brands...
Garrett?
Comp?
Any suggestions would be much appreciated.
Thanks
