Need Help Finding Injectors

Hello, I have an 88 Turbo II RX7. I'm about to upgrade the fuel pump to a Walbaro 255, install the Rtek 1.7 and add 720cc secondary injectors. I am having trouble finding out which injectors I need and where to buy them for the best price. It doesn't appear to have the resistor pack on the sidewall so I assume they are all high Independence. I would like to use the stock fuel rail and and pressure regulator for now if possible.

Punch in 720cc HI imp injectors on Ebay.
RC Injectors are good.Bosch,ID injectors,etc are also good.The Id's being a little more expensive.
You need square connector,center notch.
If you need other connectors,like the ID's would use then you would be looking at splicing them into your harness.They can be bought where you get the injector usually or come with it.
Try PL750D for a part # for Rc's.They are 750 but what the hey..good enough.

While on the topic of injectors (and rotarys of course) -

If I run a larger fuel pump and larger secondary (not too terribly larger) is there a need for a fancy tune, or will the ECU sort itself out (FC3S S4)

Maybe you could ask that in your own thread?
We don't thread jack here.

I apologize; I assumed that keeping down new threads to reduce bandwidth throughout the day would still be an occurring problem with car forums, but I guess it has been about 4 or so years since I've messed with a forum.
