When They have a rectangle plug and the plugs on the miata are oval?

 

there are a bunch of different rx7 injectors, you have to get the right ones...

 

...buy connectors, splice them in...

...get spades, splice them into your harness, and shove them onto each contact...

...buy expensive converter connectors.

 

ok, well I have aguy with injectors off a 88 NA rx, he says they are 460cc's.. BRAIN, howcome in your FAQ it says the injectors must be off a 89-91, is it because of the connectors?

 

yes...if you follow the PnP list you will be ok...the 88 NA have different connectors, but i think the 88 turbo are 550 but do work or something like that

 

yep. there are like 17 different 550 and 460 injectors. part numbers are the key. i trust they'll work, you just gotta figure out the connectors, which isn't that big of a deal....just a total of 8 wires you gotta spice.

 

My 460cc injectors came off an S5 (89-91) car. The guy had like 4 sets, sent me a photo of all of them, and said pick yours. I picked the oval connector ones. They plugged in and worked perfectly.

 

Be sure you're getting the correct resistance. I was screwed by a seller from club rx7. The guys at witch hunter set me straight. The 550 and 460 injectors for both low and high impedance are the same respective part #'s. Make sure the seller tests the resistance levels before shipping.

 

Well mine are already shipped.. what should the resistance be for high impedance?

 

I think from memory the resistance should be 14.2 OHMs or something like that.

I dunno about there in the US but I would assume the connectors would be easily available like here in Aus. I am pretty sure they are just a std Bosch connector you can get from alot of auto places and auto elecs.
