How much boost?
I am just finishing the car for this summer and am going to run the engine stock for this season.
I am collecting parts for a twin turbo kit. I am going to run 6.0L heads and a stock short block for next year.
My fuel system should be up to task, I am going to feen each fuel rail in through the front with a 6AN line then off the back into a boost referenced regulator. I am running one intank pump for now but will add an inline pump when the turbos go on.
How much boost can I run with this setup?
What boost level will dictate a change in injectors?

First of all the fuel rails, I am modifying the stock fuel rail by removing the ends of each and replacing them with a weld-on 6AN fitting.
The fuel line will feed in through the front of each rail and then out the back and into the regulator. The pump in the tank now is a stock 99 Camaro pump, I will add an inline fuel pump when I add the turbos.
The turbos that I am considering are Garret T04B's, they have a 54mm compressor wheel with a .60 AR and a P trim turbine with a .96 AR. I think the turbine housing is too large for optimum spool time but I can get a good deal on these. I think I can change the turbine housing if it is a problem.
I will build my own stainelss 1.75" headers and get them as close to equal length as possible. I am going to use two large intercoolers, one for each turbo.
The cylinder heads will be stock 6.0l heads, I think that gives me about 9.1:1 CR.
I live close to Agostino Racing so they will be doing a dyno tune for me.
Let me know if I have left anything out that you need.
