Partially correct. Depennding on who you buy your injectors from depends on whether or not that statement is true. Some "Stage 1" injectors flow less fuel than there "Stage 2" injectors. Other companies utilize the same injector but put different nozzles on the injectors.

On the larger nozzles, the nozzle holes are opened up more to allow the fuel to be released out of the injector in less time. More fuel in the cylinder in a shorter amount of time allows for a bigger explosion. Fuel needs to be pushed out in a timely fashion or you will not see the complete gain of the injectors.

ok then why is the diy-kit so much more for the stage II's than the stage I's. if i could get the stage I kit and some stage II nozzle's for fairly cheap then that would be awesome, but i don't THINK that's going to happen.

I believe the difference in cost is the nozzles.

you can do them yourself if you got the tools.

you can also do your injectors yourself with out the diy kit if you got the time.
me and "JOAT" where going to do this and where talking about in a thread and had all we needed. it wasnt a week or two later the diy company started up.
in the end i had no time and was in the process of moving so i sent mine to casserly.
cool of you to come on here and share some info.

if you want the info send me a pm and i will send you a few links. the info is out there you just gotta know how to find it.

ryan are you and the other ryan still under one roof? i think i got two injectors not firing.(i need to hook up the lap top here soon).

i wonder if you could get diy-stage 1's and some stage 2 nozzles and see an increase in power. just thinking out loud, but if you get bigger nozzles then a little more fuel is allowed into the cylinder allowing for more power and smoke.

That is what I did. Even though the Stage 2's flow 20cc's more, DIY told me that difference is only in numbers of who wants the biggest mathematical flow and will show no real world power difference. So, yes, you can do that. It doesn't really save any money though.
