injector question..please help!!!

does anyone know what size my injectors are? sorry if this is a newbie question but i have a 1999.5 f250 crew cab, 7.3. my mods are, afe blue filter intake, and an edge juice with attitude. ive been reading recent posts on injectors and doing all the research i can before i buy aftermarket or DIY's.

also, what would be an ideal injector size with my stock turbo? im possibly gonna upgrade my hpop if i do injectors, and later upgrade my turbo as i save more money. any help is appreciated. thanks

If you do Stage 2 or 3 Single Shot DIY's your stock HPOP will be fine unless it has a ton of miles on it or is already giving you problems and if it is fine save the HPOP money for a Turbonetics BB or Garrett BB and a custom tuned DP or TW Chip and you'll be set.

Looking for 05-07 front end with Harley Lights

Stock injectors are 140cc split shots.

As far as what size to go with, everyone has opinions. You're HPOP will be fine with stage 1 or 2's. Stage 1 and 2 injectors are GENERALLY 160cc single shots. Difference is the nozzle. These require custom tuning.

You can get modified split shot injectors, but your hpop may have issues keeping up with a hot tune.

Anything over a stage 1 injector is going to put a hurting on the stock turbo. If you want the best without going to big oil, get some hybrids and a BB turbo.
