Stock SE injectors?

How many CFM's are the stock injectors for the SE? Also what color are their tops? Mine are leaking and when I got a new O ring set there was slop between the block and the rail. Have a feeling that these are not the correct injectors....

680cc low-impedence orange top. should be around 2.2 ohm IIRC.
Do you have the thick grommet seal that goes on the lower part of the injector? may be the cause of the slop if you don't have. Mazdatrix has injector seal packages and pics (i think)

Yes I have the think rubber grommets on the bottoms and the squishy washer on the top plus the tiny o rings. Still play. Had to use old squishy grommet also. So 2 squishy grommets on top of each injector. Bolts are tightened down and now no more slop. But I should not have to put 4 grommets on the tops to correct this problem. And to add, I still have the gas leak from the tops in between the rail and the housing....

You may want to look at your (plastic) deflectors UNDER the injectors, in the 'block' these items get brittle over time and temp AND have two o-rings of their own. These o-rings get very hard over time. I saw them apart with a hacksaw so that the plastic part doesn't break when I (used to) try to pry the old o-rings off. Good luck.

Is it possible to post pics of these "deflectors" or describe what they look like in more detail? When I removed my injectors all I saw were some plastic grates way down inside the "block". Is this what you're speaking of? Or am I missing an essental piece?

Did you determine that the injectors are correct? The slop...is it up and down like the injector is too short? Check out these two websites from some forum members. They have some excellent pics that I used when I restored operation of my 6 port sleeves.

Looks exactly like what I saw so I guess I have everything. I'll check out my friends injectors for his SE. He said he'll give them to me.
