With the 22re what is the stock amount of psi the injectors produce? has anyone out there used anything other than a toyota injector in its place? ive noticed that the 21lb injectors off my 88 350 tuned port trans am gta have the same plugs and this has me curious..

Injectors don't produce psi; they're just valves. The Fuel pump creates the pressure, and it's regulated by the Fuel Pressure Regulator. Which doesn't regulate to a fixed pressure, but a fixed pressure above the pressure inside the intake manifold (so that the pressure across the injector is constant. (about 50psi)

So I have no idea what a "21lb" injector would be. If what you're hoping for is to swap in an injector that would spray more fuel, all you get for that is an engine running (or maybe not running) over-rich.
