Default Which RX7 injectors do I want?

What year RX7 injectors are the 550CC and what color are they? Also what are the 460 CC injectors from? Thanks for the help. I am trying to get the plug and play injectors for my EMU setup.

I have a set of 4 purples that were just flow matched and cleaned last month (have the invoice). I am going with a different direction, so if you want to buy them let me know.

Thanks for the info. Keinayo how much do you want for the injectors? I tried to PM you but your box is full.

I think I have some NA RX7 injectors laying around my house from my brothers race car (he races an 89 NA RX7 in ITS). I will check tonight. I am not sure if the spare injectors are from an 89-91 RX7 or an 86-88 RX7. How can I tell the difference by looking at them? Are the 86-87 RX7 injectors a different color than the 89-91 ones? Are the part numbers printed on the individual injectors? Thanks again for all the help.

Should have more space in my PM. However, I want $150 shipped for the injectors.

Just as a data point, I am running the 460cc injectors on my 1.6l M45 running e-85 and only hit about 44% duty cycle during autocross runs.

I just purchased some 460's and they're at cruzin performance getting cleaned now. With the extra headroom I could run E85 but they don't sell any near here :(

Our local station has e-85 for about ten cents less than our low grade 85 octane. $2.89 versus $2.99 but I saw e-85 at a station 30 miles north of me for $2.19 today.

yeah maybe you won't need 550cc injectors, my rx7 550cc injectors are flowing 620cc, at 7psi my duty cycle is 14%
