do i need bigger injectors?

[F1atlander]

im about to do a HCI swap and im wondering if im goin to need to replace my 19# with 24#.
just a mild hci swap with a 2.02/1.60 60cc heads, ecam, and a gt40 intake. i already have a set of 24#s at the shop waiting. but what to do about a meter. can i just swap a meter and injectors on my car like i did on my fox?

 

[Javi]

no need for the bigger injectors.. id put the money somewhere else

Id use the 24's for piece of mind. Your gonna need a tune anyway. Use the stock meter and tune for 24lber's

 

[F1atlander]

so their is no doubt that ill need a tune?

none you will need one for best performance.

if you run a more mild cam, you could get away without a dyno tune for now, but the 94/95 computers dont like the cam swap and will lots of times buck at low rpms with the lower vacuum. some times with a hci though you can just swap the meter out and you'll be fine.

you will get more performance with a tune though

Funnily enough i'm getting rid of my E-Cam and getting an Anderson B-31, the idle with the E cam is almost hopeless on mine, apart from that its a pretty good performer.

I usually don't reply twice to these threads, but you you are doing a mild hci you won't see over 310's.. You will BE FINE with stock injectors..

Why even bother? If you have your heart set on doing a 351, just wait.

No need for 24's. On an N/A setup, 19's will support enough power for a mild setup.

I put a B-31 in my 94 Cobra with TFS heads, untuned right now. The car is a different animal now, the idle is very mean sounding, getting on it in first gear is about useless instant tire spinning/smoking from 2000-6000 it pulls very hard. Once crusing speed it drives very nice alomst stock like. Untuned I'm knocking down 320 miles to the tank 75% highway, I was at 350's with my GT40 heads/stock cam. My boss pulled in at the same time I did the other day, she's like that's a pretty loud car you have can't wait to get some boost and a tune and see what this thing will do.

Thats good to hear, just out of interest does it idle ok? {apart from the sweet sound ]

ok so why does everyone say you dont need 24's on all of these upgraded motors when alot of them are upgraded past stock cobra and the cobra comes with 24's . just wondering cuz i thought i would have to step up to 32's when i build my 331 this winter with afr heads and an f-cam with 1.7 rollors.so please explain why?

F cam? to each their own..
you should be fine with 30lb injectors.
use the chart and coversion table listed on the following link.

[95-stang]

Well i was told 19lb are good to about 300hp, when i got my crate motor [rated about 340 at the crank] i was recommended to get 24lb so the 19s were not being "overworked".
Looking at the Anderson Ford site they say if your fitting a B31 cam to use 30lb, so yeh its confusing.

 

[bradtheblade]

only reason for f-cam is that i was told it was the largest i can go with my 1.7 rollors and still use my stock cobra covers i am however open to suggestions.altough i will not change my stock covers.
