My buddy is over hear and wants to get bigger injectors for his 2.2L what size injectors come stock on these?

 

24# i think. its 20 something...maybe 28?

 

do ppl knw how much gain i would get if i put lets say 42# injectors in? for a 2.2

 

How about nothing and some auto repair bills.

42# is what I'm running and I'm turbo, 42# would flood your engine not enough air, mix would be crazy rich.

 

oic, well what would give me gains?

 

Your stock injectors are good. Intake/exhaust/2.4 manifold/tune would get you some decent gains.

 

after intake, intake mani, tb, stg 2 cams, header, dp, exhaust, and tune (retuning now) im installing lsj injectors

 

well, first thing you should learn is adding fuel is worthless without adding more air, and air is the limiting factor in making horsepower. injector swaps dont give you horsepower, they just allow you to run higher horsepower.
For example, your stock injectors can create anywhere from 3hp idling, to ~190hp under WOT (assuming you've done some mods). 42lb injectors can create 3hp to ~275hp under WOT. However, buying 42lb injectors wont mean you'll have 275hp when you go WOT...it just means that they can support that much power. get it?

 

^^props on that.

I get it now (not that it matter I have an SS/SC)

 

thank you for informing me and not flaming +1

btw i get it now thanx
