As long as its 12volts, has a plastic pump diaphram, it should work.
What pressure depends on nozzles used and fluid requirements of your motor. So a StageII with a roller cam and aluminum heads will have a different requirement than your application.
Typically want at least 3-4 bar pressure(45-60) PSI so the nozzle mist's'.. above that .. is for fine tuning.
