This is found in the FAQ
What size injectors does my RX-7 use? What colour are they?
Year Engine Plug Size Colour Part #
84-85 13B NA, low square center, 680cc, orange, 195500-0900
86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350
88 13B Turbo, high square offset, 550cc, purple, 195500-1370
89-91 13B NA, high oval center, 460cc, red, 195500-2010
89-91 13B Turbo, high oval center, 550cc, purple, 195500-2020
And if I understand correctly using low imp. injectors could burn out your injector driver circuit on the ECU if left on too long. If you had red injectors before the the rebuild, Was it an NA? Good luck, Hope this helps.
BTW, Next time you might want to look in the FAQ before some search **** gets on your case. All kinds of useful **** in there.

Look at the plug for the injector, this is the notch in question. I have attached a drawing to illustrate the difference.
As far as the part number goes, it is on the side (hold the injector with the plug facing left or right) on the plastic part.
Hope this helps ya!

All RX-7 smade after 87.5 are high impedance.
A sure fire way to tell is to look for the injector resistor block. If there is a block, then the car is low impedance. Check the Factory Service manual for the location of the fuel injector/solenoid resistor.
