Injectors
Ive got a 93 z28 w/ cc305 +about all the bolt-ons (A4). I have an intake leak so when I fix that I was prolly gonna put in bigger injectors and an adj fuel pres reg. Am I gonna add any hp? Do I really need the computer reprogrammed? What size inj would be good?

I think 30s would be a little too much for him. Accel also makes 26 pound injectors, but I don't like Accels.
The 93s came with 22 pound injectors which means he's maxing them out pretty much. The Ford SVOs were rated as 24 lb/hr at 39.2 PSI. On our pressure of 43.5 PSI, they will flow just around 25.5 so that should provide enough fuel.

I'm right with ya Madwolf.....Accels are horrible but people buy them because they are cheap. Accel 30's actually flow 27-28. Typically too big for a 350 CI engine...the ECU can't shut them down enough at Idle. SVO are made by Bosch and are much better quality.

As stated earlier you should get come SVO 24lb injectors, AFPR, and programming (for the cam). When I installed an AFPR on my car I picked up 10 rwhp and 17 rwtq just from increasing my fp from 39 psi to 41 psi.

What do you have in your car that requires "83 lb Sieman injectors"
how about a 350/355 with a c306 and ported heads? what injectors should I get?

I'd love to see the spray pattern on those Siemens injectors hehehe those and Tomco basicly don't have one. Just a straight stream of fuel coming out. Like pissing on a rock lol

Perfect comparison! (it's called a "pencil stream" BTW)
Here's some Siemens 95s for ya!
Also see some Bosch 88s here. Looks like a much better pattern to me...
