Which injectors do I need for my L92?

[scherp69]

As the title says, I'm trying to figure out which injectors I need. Not sure what you need to know about the motor, but here's the details:

L92 (may or may not keep the VVT)
Hope to be in the mid 500hp range
Using a FAST 102mm intake with Nick Williams 102mm throttle body
Fast billet fuel rails

I'm looking at the FAST injectors and don't have a clue what size I need: http://www.fuelairspark.com/Products/FS-%27Fuel%20Injectors%27-1.aspx

They have 39lb/h, 50lb/h, 65lb/h and 85lb/h ones. Which ones do I need?

Thanks in advance.

Stock LS3 injectors are cheap and work perfect. The L92s are too small for any power increase

x2 you're not going that big or powerful yet. The stock LS3 injectors will support a lot of NA power

Thanks guys. Like I said, I know nothing about this so that's good to know. Will save me a bunch of money too.
