I installed a f22b dohc in my 92 honda accord. when i did so, i used the intake off of the f22a1 motor. Should i upgrade the injectors and fuel pump? To get the full potential of the motor. And which ones would be best?

 

No, you don't need to. The stock components will be more than enough. Even it works good with the H22 setup.

If you really want, you can always do a 190lph fuel pump. But like I said, your stock ones are more than enough.
