some of my mods are listed below. i have 24# injectors but i had no real choice. my stock injectors were literaly falling apart so when i bought my afr165's, i had to get new injectors. i didnt want to get 19's again so i just got 24# injectors....not so sure i need them but id rather have gotten them now then when i needed them i had to buy 2 sets

bobby

i would go ahead and get 24's

i have always heard the stockers are good to 300 hp.

24's and a good regulator.

nemethjames1

you do not need anything bigger then 19 if your pushing 300, give or take a few... thats what they are rated at...

hey grabbem did you get the letter yet? i got the regulator in the mail yesterday, i still dont know what gasket you said i gotta replace, is it that little black one? where it mets to the fuel rail?

on a NA motor the 19#'ers are good for 304 flywheel hp at stock fuel pressure. with a fuel press reg and more fuel pressure you can get more out of them. Its a good idea to shoot for no more than 80% duty cycle reguardless though, and the # above is at 90% but would be similar at 45psi.

If your blown then you won't get as much hp outta em because your running a richer mixture.

Unless you are building a race car, they are not needed. If you are punching out a lot of power then you can switch to 24lb. Injectors. Or if you need to get new ones because they are falling apart, go ahead and upgrade to 24# if you are still planning on modding more, who knows, maybe one day you'll be charged or blown...
