are these the right ones your talking about? Bosch 0280155968 Fuel Injectors
i also found some on fuelinjectorconnection.com
they are the bosch BLUE DEMON 3 modified
which ones would be the easiest? no fitment prob. or connector issues?

I also suggest slowing down. Judging by the parts used in your build you have a lot to learn.
You can't just swap in larger injectors - you need a tune or as mentioned above you'll dump tremendous amounts of fuel into the cylinders, likely washing out the rings and doing other very bad things.

If you're getting a 58mm TB then make sure you have your intake ported to match it.

I have a used BBK 58mm from Jason Short but as soon as Xmas is over I'm going TPIS. But if you're on a budget search the for sale sections in here and camaroz28.com. Someone is always selling a 58mm TB.
For now put your $$ into your heads and intake. This is where you'll make most of your power.
