RX7 Injectors for NA-T ?

[dejacky]

I'm playing with gasket/ rubber o'ring configurations to achieve the best fit possible for these into the intake runners and fuel rail. Anyone know of good combinations that work?

wow did that really work for you i was looking at doing that to my friends car, let me know how it goes too, and also what gen. and type of rx7 did those come from?

Yes, the injectors seemed to work fine. Exhaust and headgasket are getting installed, hopefully car will be done this coming week :fingersx: . I think these are the famous 550cc "purple top" injectors that have a 605cc flow rate capability. If I'm not mistaken, they're from the late 1980's / early 1990's Mazda RX7 turbo cars. They're "high impedance" (compatible with stock injector harness) and even clip into the stock injector clips :cuddle:.

Here's a short video of them in action when I first got the car to idle (with Gamimnon's help!) after the NA-T install. So, it's untuned in this video. :yumyum:

Btw,
I ended up RE-using the lower grommet from the stock injectors on the RX7 injectors, so I did NOT double stack them as in the picture. :wackit: If you choose to use RX7 injectors like I did, PLEASE have them flow tested and blue printed by a reputable company before installing them on your car! :sleep2:

How much were those injectors and where did you find them at?

[dejacky]

they're cheaper than buying new 605cc or even 550cc injectors. You can find them on www.ebay.com or try some mazda rx7 enthusiast forums. :)
