the stock injectors on a 2.3l are 12 lb and the 5.0 are 19lb, i had 5.0 injectors in my 2.3l for well over a month, but it was hard to start and spit out black exhaust, but it really liked WOT!!!!!

Exzactly. I got the 17lb injectors and they love the WOT. Any of the injectors in the list above deffinently works in any fox body 2.3l.
WOT = wide open throttle...why are you changing the injectors? Why not just buy what is made for the car, either stock or upgrade... Don't cheap out, it only costs more in the long run...you may need to retune the car if you change larger injectors

Yeah. It runs better with the bigger injectors but it does feel a little weird. But it does haul though.
Ok, I think we are missing the boat here! You can safely run 17-19 lb injectors with an AFPR and no computer tuning. That is not the end of the road though! You can run whatever high impedance injector you want in a 2.3 N/A motor as long as you tune the computer. How do you think the turbo guys run 52pph and up injectors and idle just fine. (I know, I am a turbo Ford guy) It can be done with a N/A motor as well. I am about to tune a 2.3 N/A to use 42 lb'ers here soon. Why would our N/A motors be any different at idle or under cruise than a turbo would be, save for a few internals? We have been tuning the Ford EEC Computer for years and it has gotten more support and cheaper to do as time goes by. So I will take the lead on this one and get back to you. By the way, the 5.0 guys have been running 42lb injectors and matching MAF calibration for years. It is a bandaid, but works! I have a friend that is about to embark on this venture with a 2.3 N/A this week as well. He will be using a 70mm cal'ed for 42# injectors on a 2.3! I can't wait to see what happens! I recently got my hands on an APEXI NEO and used it on my turbo Stang with MOPAR 52 lb'ers and it ran like there was no tomorrow. Idled smooth as glass. So there is another way to upgrade injectors and get the power and drivability you are looking for. SO just because it is outside the bolt on and go realm, doesn't mean it can't or won't work on these motors.

I know this post is old but maybe you can answer my question. I know lots of people are gutting the intakes on their turbo stangs for more flow, if you do it on an N/A engine it will work but kill your tourqe, which leads to my question. if you upgrade to new injectiors and gutt the intake would you still have your torque and get increased horsepower? p.s i also have a cold air
Injector upgrade 
Bigger Injectors
