Where can I buy an oil pump?

[alexander]

So, Im building the classic gas turbine made from a car turbocompressor. As far as I could find, the ideal pressure is about 50 psi and a flowrate of about 2 gallons /minute (10 l/min). Where can I find a pump with similar characteristics? (Keep in mind Im not from the states)

What sized turbo are you intending to use, as this will influence the flow required ?
