what pressure should I expect? I read somewhere that 1.200 psi should be enough, is this true?

Typical brake line pressures during a stop range from less than 800psi under "normal" conditions, to as much as 2000psi in a maximum effort. Line pressure can only be increased by either increasing the mechanical pedal ratio or by decreasing the master cylinder piston diameter. In either case the pedal travel will be increased.
Your braking system is no better than your tires and suspension but good quality brake pads/shoes are a must also.
