Default New injectors

Hey fellas, i'm going to be upgrading my feul system a little and I was just wondering what size the stock injectors are on a 2,001 Gt? You see along with a high flow fuel rail kit i'm thinking of getting some 30Lb Venom high performance fuel injectors. Will they be too much or not enough? My mods are as follows: K&N cold air intake, stack racing 75mmtb, accufab upper intake, professional products intake manifold, bbk underdrive pullies, bbk headers, bbk high flow mid pipe, flowmaster exhaust, frpp 4.10 gears, diablosport tune. I think that's about it. Thanks for any info.

Don't bother with injectors. The stock injectors are 21lbs and are more then enough for bolt ons.... Unless you get a power adder you pretty much won't need bigger injectors.

you have absolutely no reason to be upgrading your fuel system right now unless you have future plans for a large dry shot of nitrous or a blower.

What color are your injectors? Ford changed to the pink (21lb/h) injectors in the mid-2002 MY, if you have the orange 19lb/h units then upgrading to 21's (or 24s or even 30s) and tuning for same makes sense.



The 19s are maxed out at 90%+ duty cycle in the PI engines--that's why Ford switched to 21s...
