    Almost sorted out 323GTX

    Looks like a great site to help Mazda lovers out!
    I have a 1988 323GTX which has a fresh motor and a whole bunch of other stuff done but I am struggling to find OEM injectors! Two of them are pooched and I have a set of four which are close but flow more fuel than the little beast can use right now so e-tests are a problem and power is also suffering.

    Does anyone have a source for stock injectors? I have been looking to no avail!

    what exactly is wrong with your current stock ones? most injectors can be cleaned/rebuilt back to spec. try www.witchhunter.com, or perhaps some other injector cleaning service thats located in canada (i'm sure there are some)

      I have had the injectors cleaned and flow tested and two of the four are not salvageable. As I had great difficulty finding the exact match I installed an injector that flows 5cc more and hoped it would work but alas it is just too much fuel. After careful inspection I believe that the best solution is stock injectors or an aftermarket injector that has the same flow characteristics.

        clock the airflow meter 1 or 2 clicks leaner & try the 5 cc injectors one more time

          That is worth a try, I understand that advancing the timing will help to. Right now the exhaust gas temp is running around 500 at idle and is coming up to about 1300 at 10 psi of boost. I think that is low.
