I found this ( http://www.witchhunter.com/subarumod1.php4 ) while looking up fuel injector cleaning. Maybe it will help somebody. Scroll down to the bottom of the page. Sorry if it is a repost.

(FD 850s on the right) that spray pattern was intentional I'm sure due to the design of the FD LIM.

 

interesting, the more milage the better lol, but what if cleaned and flowed? would it still be the same then or considered new?

 

^ I thought that was interesting as well. I am assumeing that, because they are not changeing the coils and other major parts that i would not be considered new and would have no effect on the flow rate other than what is cleaned.

I am sure the spray pattern is what Mazda wanted, Seeing as how the injectors flow into the sides of the runners and hit angled deflector plates, Mazda wanted a consentarted spary not a dispersion. besides the dispersion spray on the left looks bad, would think it should be uniform, besides what does an WRX tuner know about RX-7's other than the shape of our tail lights.

 

here is a video of them flowing, not just a picture if anyone was interested http://www.youtube.com/watch?v=yLbY5ZBo_FA
