Injector question?

Hello everyone, I just have a quick question. I was wondering what year/model RX7 had the largest injectors, and how large are they. I am running 550's from an RX7 and I have them maxed out. Any info would be greatly appreciated. Nick

By the way, its for this:

Oh god, a Probe!

The largest top-feed injectors you will find on the RX-7 are from the '84-'85 GSL-SE. They are 680CC.

Yep. And assuming your are using the s4 injectors (they have a square plug, not oval) then they are a direct swap.

I am using the oval type, but if I have to change the harnesses I will. Thanks, Nick

It's also FWD...

And if it wasn't explicitly state, the 1984 - 1985 GSL-SE only runs TWO of them, so you'll need to find two "sets" to run your 4-cylinder.

You're betting off buying 720's from an authorized GReddy dealer.
