If I send my stock fuel injectors to RC Engineering to have em balanced and flow matched, can I use a set of injectors from a 92-95 Civic DX (D15B2, I think is the engine they came out of) temporarily? My car has the stock D16A6, if that matters.

 

I think your injectors are peak and hold(low impedence). The 92+ ones are saturated(high impedence), so they wouldn't work. If you could disconnect your resistor box, they would work, but I don't know how easy it would be to do that without having to rewire the lines.
