injector sizing and rail questions

Im am very close to being able to start my TII engine in my fb. just got the haltech and the OBX turbo manifold (which is a piece of crap and needs some work but for $175 shipped who cares)
I need to finish the fuel system...

question 1: on a S5, can you put 1300s in the stock secondary rail, with some AN fittings welded on??

I was planning on going with a full 1600/ fuel rail upgrade, but that $300 right there and I am fairly broke at the moment.


question 2 how much can 550/1300 support? how about 720/1300?
heres my setup,

stockport s5 13b
tubular turbo manifold
T04b 60-1 .7 AR/1.15 P trim with a full Stainlessworks exhaust.
volvo intercooler,

12-15 psi on the street 18-20 on the track.

You have to modify them a little at the bottom to make them fit in the engine. The fuel rail can be bored out, I think.
