When do need bigger injectors?

[Connectorhector]

1995 mustang GTS. Started with a valve leak..... Tore it all apart and never stopped. Lol. Just wondering when do I need to get bigger fuel injectors? Bored it out .030 new pistons and rings. Dipped and decked it 190 heads. 75mm BBK upper and lower intake. Haven't got a cam yet but I was just gonna put new 19lbs injectors. Will that be good? What would I have to do be able to put more gas and air? Larger air intake. I don't really want to turbo yet but I am planning on checking out a nitrous kit soon. Never been around it yet gotta try.

19's support somewhere around 260hp @ 80% duty cycle. 24's would prob be better bet for you they are about 330hp @ 80%. If you go power adder thats a different ball game.

If I go to 24s do I need to change the fuel pump and also will the car just automatically spray the right amount of fuel for the air it's getting or do I need to have some sort of fuel management. I'm hoping just put them in and voila. Lol

Like ram said I'd recommend running atleast a 24lb injector.

Assuming you still use a MAF you'd need a MAF calibrated for the 24's. I'm not sure on the fuel pump. If it's stock and good shape maybe. I know all my cars I just put in a 255lhp they are cheap like $100 and that would have you covered w/ room to grow.

with that list you will be lucky to get away with out a tune and would be better off planning on one.

Yah I just don't wanna drop the tank to change it. Lazy. Thx though.

Ok so to get a tune what is that exactly. They tune it so the fuel air is all good by putting a new MAF and setting it? I know probably sounds like I know nothing. Ok I know nothing. About tuning for sure.

For how long it takes to drop the tank I'd reccomend it. I change the pumps on these turds right away. While ur at it I'd install a cam as well to benefit with the new heads and intake and like said above you will need a new maf. If also start looking into a tuner not a hand held someone you trust to to your car
