Fuel injector size

Hi,

I need some information.
I know that fuel injectors from h22a are 345cc
From h22a2 they are the same size 345cc or different?

So a bb8 has 290cc, right ?
Are they compatible ? Like, could a 5th gen have h22 injectors ?

That makes no sense.

I think he means can a 5th gen which normally runs 290cc saturated injectors run the 4th gen's H22A's 345cc peak and hold injectors.

Short answer is no. Long answer is yes, but you need to also install the injector resistor box into the wiring as they work on a higher impendence. But you can't just plug both in and go. You would need some form of tuning to adjust the injector sizing. Can I ask why you want to do this exactly?

If you want to die of boredom (but learn a little), I'd recommend a little read of my fueling section of my build thread:
