I have a JDM spec supra want more power like 500hp crank

what is max hp the US spec steel turbos can get at 21 psi?
can you get more fuel by just increasing the voltage to the standard fuel pump from 12V to 14V? and still use the stock injectors? what are the downfalls if possible?

your jdm spec supra has less agressive cams, smaller turbos (though ceramic) and smaller injectors than our cars (440cc vs 550) you will not be able to get the same power that we can. bpus on race gas and 21psi have shown over 500 crank in some cases. its probably about where i am at 21 pounds.
