  • Will these injectors work in a 91 3.4L DOHC?

    i am looking on ebay for new injectors but nobody has any for a 91 3.4L dohc but i found these they are for an earilier style 3.8l



    will they work?

    if not how about these?



    or these (3.1 , 3.4 single cam)

    or these 3.8 camaro



    i dont care about extra performance, it is only for basically a stock engine, i dont want any of them that will Under-fuel the engine i would rather get a little more performance than ruin the engine because there is not enough fuel. actually since they are all close to the same price if they all will work which one will give a little more performance? thanks for the help.

      i have a set of 97 dohc injectors f/s. i know the 3100/3400 are 17's i believe. too small you have 23lbs. 3.8's are probably 19 or 21 but not sure. i can sell you my set for $60. also i have 4 injectors from a 94z at $7.50 a pop and 6 lt-1 injectors which are 23's as well for $2.50 a pop but they are untested.

          yep they ran fine be4 i went to 30lb ford injectors. i didn't look at the odometer of the car so i am not sure. but they are clean if i had to guess 60k. also i have heard rumors that the newer injectors cure something referred to as "phantom stalling" on the earlier cars.

              how are the 97 injectors different from the 95 for the DOHC?

                ill have to get back to on the 97 injectors, i might take them, how much more perormace did you get with the 30lbs injectors, and how did your gas mileage get affected?

                    those accel injectors should work. i don't think there is a difference between 97 and 95 injectors. the 30's i have are mainly for 2 reasons. i am going to a 75mm tb with ported upper and lower intakes. and later i plan on going turbo(not to mention the n20 system).

                    i wouldn't recommend them unless you are heavily porting,boosting or spraying the engine. i plan on all 3
