I think our short term fuel trim pegs out at 25%. That may mean 290's will work without any mods. With some slight fiddling with fuel pressures you could make a bigger injector work <310's and up>.

Is it possible to modify the stock fuel pressure regulator to drop it from 50PSI@idle to about 35PSI@idle, so to reduce the need for aftermarket adjustable regulators to set base pressure?
drill out the hole a little bigger, cut a coil off the spring, different spring??

In the new turbo, they list cars and the types of injectors they use. Turns out that the NT Supra uses 315cc "saturated" injectors. Also the RX7's use saturated injectors but I forget what size. I know they use some small primary injectors and then some large auxillary injectors. Wonder if any of them will fit? I know they all use Bosch style pintles but don't know if they will fit geometrically wise.

The stock OBDI FPR is pressed together, you can't really open it up to "adjust" it. But...you can modify the stock FPR so the fuel bypasses it. You then need an aftermarket FPR to keep the fuel pressure where you want (35 psi or whatever). This is what I did. Instructions are here: http://members.nbci.com/cbehnken/fpr.html
