I tell you everyting man, those 1.8 injectors just get em marked at pap so you can return em if they do not fit. those 1.8 injectors are like a 230cc where the 1.9's are I think around a 170cc, correct me if I'm wrong guys but the 1.8 injectors would be way better than 1.9's, AND they are 1.50 each at pap, that's 6 dollars man.
I've also heard of the thunderbird V6 injectors possibly, or a fuel injected 460 it has monster injectors with the same wire clips.

im pretty sure the bp injectors have different connectors on them and the factory cvh injectors are only like 14lbs which is like 150cc. I doubt you could even run injectors that big without flooding it because if you bring in more fuel you have to bring more air in too its all about balance you can't just throw a ****load of fuel at something and expect it to fix your problems. :? oh and the injectors from early 90's ford 4.6 v8's have the same clips and length: they are 19lbs or 199cc but its still too much without introducing more airflow.
You will need custom programing if you want to run bigger injectors. If your engine is running lean now just wait till you see how rich it will be if you go up a size.

MTN_RCR, i've already upgraded the intake but still runnin a 1.9 TB with a bigger MAF sensor. and madmatt, if i'm understanding u right, ur sayin that i'd be runnin too rich in city drive but just fine in the freeway then i'll just stick with swapin the computer. the escort that i took it from didn't say what year it was in the door panel so i have no idea if the pcm i got is obd1 or obd2. is there a way to find out?
Only the 96 Escorts had OBDII so the chance you got one is remote. There should be a number sort of like this on the computer (F7CF-12A650-DC), Google it and that will usually tell you what car it came from.
Is this ECU from the same car you got the bigger MAF from? If so I think another way to tell is if the plastic part of the MAF is black instead of gray than the car is OBDII.
91-93 Small MAF

94-95 OBDI

96 OBDII

my origional MAF sensor was black. the one i got from the junk yard was grey but the sticker inside the door panel said 93 so it had to be a 94 escort. that car isn't there anymore. the car i pulled the computer from didn't have a sticker in the door panel and i don't remember what color the MAF sensor was.

I run a '92 escort on a 1/4 mile paved track, and am mostly running over 4500 revs. Would I benefit from bigger injectors? I'm running no air filter, and have a '92 gt, and a '92 mazda protoge lx. If it would benifit from more fuel, would any of those injectors be bigger and still fit?
As has been said, going up on the injector size is just going to make your engine run rich and loose power. I would still run an air filter, a cone one. I would also swap to the newer 94-95 computer and MAF. Then swap in a the larger throttle body from 97+ Escort and port the intake for the larger size.
Its tuned for the larger MAF and has better fuel maps.

also, if u have a car that runs without the EGR equipment, just get the egr sensor and solenoid u'd find on the firewall. u already have the wire harness set up to connect them. just need to figure out where the vacumme lines will run.
