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.
