Which injectors?

I have a '90 GTA with a 350 L98 bored .030 over. It was a stock rebuild. I need to replace the injectors but not sure on what size to get. I was told to stay away from Accel from a few people and I keep hearing about the ford injectors.

Can someone point me in the direction of these injectors? And will they require any changes to the ecu?

EDIT-

will these work?

Im no expert, but I think they are small for your application. 19 lbs came on 305's, while 350 had 22lbs injectors. Stick with the original size injector and no other mods should be necessary. Ford injectors are a great choice I hear, and remember they flow rate them at slighty lower pressure (40) I think, while your furl rail will be pressured at 43.5. shouldnt make mods necessary.

go to fiveOmotorsport and look into the "pink" 22lbs injectors, they work good on my ride.

good luck,
joe

I am still recommending the Ford 24 #/hr injectors, along with an AFPR by Holley. I have been running the FMS 24s since about late 90s, no problems. These are the right sized injections for a 350 or stroker from 250 RWHp on up to 400 RWHp with fuel pressure adjustments.

if your looking at injectors to buy I got 24 pound injectors for yea...they have about 10k on them, and worked when I took them off...I'll ship them to you for $75 bucks Just PM me

Oh and I reqimend 24 pound injectors if you go any bigger you might be too rich. There is also the matter of what your going to do to the car...if your going with a bigger cam? exhust? just things to keep in mind. Because if your going to mod it up the butt you might want to get bigger injectors than 24 pounds just so that you don't have to buy an extra set.

Oh yea only one problem...at least you may think it is a problem...they are accel injectors. I never really heard anything bad about them...then again i haven't heard anything good about them...just letting you know.

stick with 22lb injectors. They'll support 400bhp no problems and they'll work 100% proper without changing the computer programing.

Is that the Bosch 22lb injectors that look pink on their website?

Bosch Injectors - 0280150561 D9B-22lb
8/Set: $239.50

Stupid thing is they have the same set in a different area listed as:
8/Set $298.50
Bosch 22.5lb - NEW
0280150561
Flow-matched Set

Not sure about the pink ones, but the price difference belongs to the fact that one set is flow matched while the other is not I suspect.

Thats the wrong part number: for a 350 you want FMS part # M-9593-A302.

The A302s are 24#/hr injectors,,,, the C302s that you show are 19s,,, you definitely want the A302 for a 350,,, and while you are at it, itstall a Holley AFPR.
