I just bought another FC and will be updating the ecu with the Rtek computer.
question is what colour are the injectors or part numbers that will fit in a 1989 turbo rx7?


19500-2020 are the ones that I have which are 550cc.

Where can I get 720cc?

Many places sell top-feed Denso style injectors that will fit all FC fuel rails. I bought some Greddy 720cc injectors for my car, which are really just Densos. They have a light blue top and are low impedance, which means you'll need to wire 6-10 ohm, 10-20 watt resistors inline.

I would rather not wire anything into the harness. Don't they sell normal 720cc that would drop into a 1989 turbo II?

Thanks for the info.

If by "normal" you mean high impedance, good luck finding some. Almost all aftermarket injectors are low impedance. The wiring is simple and can be done at the ECU side of the harness.

Here's a pic of my resistors. I have a high impedance harness w/ all low impedance injectors, so I used four 6 ohm resistors.

Thanks for the offer but the Rtek mod needs 720cc injectors.
