    Extra fuel injectors?

    I've seen it done on RX-7s, and I'm wondering if such a thing could be done with the scooby. Supposedly it allows great driveability coupled with the fact you can flow a ton of fuel at high boost/RPM. I know the TEC-3 supports extra injectors, but could it be done? Has anyone done it?

    Yes, you can use more than 4 injectors, but there's no need unless you're making quite a bit of power. It's not cheap.

    You can easily get a stable stoich idle from 650cc or 660cc injectors. As large as 800cc, you can still get a decent idle - if you need more fuel than that, then you should look into secondary injectors.

    If we're talking about a "5th injector" type of setup (as opposed to 2 per cylinder or some such), how well does the WRX manifold flow "wet"? I'm curious about this because it would make a difference for nozzle placement on a single-point wet nitrous system, too...
