q45 injectors on a ka24de question.

[Roger_cha]

as the title says, if i put the q45 injectors on my ka does it make my ka run rich or is it a perfect upgrade for it... my ka is stock with bolt on and stock ecu or do i need to get it tuned if i put the q45 injectors on.

I have no clue what cc & impendance q45 injectors run @, but w/ stock ecu, there is ZERO reason to change your injectors for performance upgrade.

As long as you are n/a & your stock injectors are working normally, you should never need to upgrade them.

x2, changing your injectors would do nothing unless you were boosting and or tuning.

plus q45 injectors won't fit on a ka, they are way different i tried asking this question befor and thats what i got fo an answer

[Roger_cha]

well i heard that q45 injector would fit on a ka its just like the sr injectors. plus i just saying would i get a good amount of power if i upgrade them. but my plan is that try it on stock ecu and no boost to see if it makes a different if it dont then ill be boosting it.

100% w/o the proper tuning, your car will run like complete crap w/ any "upgraded injectors".

don't do it. period. you're ecu is not tuned for anything other than stock sized 270cc injectors.
