Pressure relief valve on PS

Hi all I'm using the 99 vvti engine to power a custom off road buggy and going for full hydraulic steering.
Couple of questions I cant se to find the answer to
1. What gpm does the PS pump kick out roughly
2. Is it about 1250psi
3. Does the PS have a built in pressure relief valve so I don't need on in the circuit?
Thanks dan
