Injector sizes
 

Hey all, I'm just wondering what size injectors come on each year and type of RX7. I have heard that the 1st Gen turbos come with 850cc/min injectors, and was wondering if I could verify this or find more information in regards to injector sizing on the RX7. Also what type of injectors are these? I'm looking for a more affordable OEM application to install on my 300ZX(original reason I registered on this site is to help my friend out with his 87 RX7, but I figured it might actually prove useful for myself as well). I am purchasing the SDS EM-3-6F system for my Z, and so I will be making a custom fuel rail for this, so they don't have to be exactly the same as my stock injectors. The way I see it, if I can get a dirt cheap set of injectors from the junkyard and have them serviced, I can save a lot of money over buying aftermarket injectors at highly inflated prices. Oh, and please don't knock me because I'm a Z owner, because I don't knock any of you for being RX-7 owners. I love my Z's just as much as you probably love your RX7's. Thank you in advance for any assistance you might be able to give.

Good luck finding a 12AT turbo motor from Japan-only SA22C in the states!

The -SE injectors also have rectangle plugs. The low impedance ones have the ''tab'' in the center, and are greenish blue (bluish green? :)). The high impedance ones have the ''tab'' offset to one side, and are reddish colored.
