24lb'ers are DEFINETLY enough... you could prob run your setup on the stockers if you really wanted to... you might be pushing the DC a little far but I bet you can do it. I would still upgrade I was just making a point

I would definitely go with the 24lb. 19lb supposively hold up to 300rwhp but that is really pushin it. But 24lb injectors will be plenty, they hold up to about 350rwhp.

Consider how far you're going to go in the long run. Might be worth staying with the 19s a few months if you plan on adding a nasty shot or blower in the somewhat near future because then the 24s may not be enough.

If your gonna upgrade your fuel pump just get a 255lph. It'll be there for when or if you need it in the future, and its not gonna hurt you now.
