Have cobra intake, what about injectors?

[catman4115]

I receltly purchased a cobra intake and was wondering if i would need to upgrade my injectors and mas air meter because i wasnt sure if it would run alright with the 19's. Also is there a big decrease in gas mileage with the 24lb injectors. Thanks for the help guys

You definitely don't need to upgrade injectors at this point. You should consider a bigger throttle body and mass air meter but you don't need them to run the manifold.

well i have a 70mm throttle body too. but the Mass air meter is stock. I wasnt sure cause on the 93 cobra it had 24lb injectors. If i were to go to 24's though is there a big decrease in gas mileage?

i think the 19's are good enough until like 280hp.

24's will cause the car to run rich, which would likely effect mileage. The stock meter is calibrated for 19's you would need to replace it. You could get an adjustable fp regulator but I think the 24's would still be too much.

i also want to add that after tonight my car started smoking more than usual and it kinda sounds like a disel. any guesses on what it could be?? thanks guys

up to 300 horse or even more on 19 pounders.

also, I wouldn't go larger than a 65 mm throttle body unless you're running with alum heads and a good cam.
