Cooling the turbo.

I have a 1990 RS and am istalling a 14B mitsu turbo, has anyone cooled this turbo? Any hints or tips before I start. The turbo guide doesn’t say much about this.

Parts needed?

Where do I tap into for the coolant?
What size are the fittings?
What size are the hoses?

I’m pretty sure that you have to get the fitting from mitsubishi. I’m using a 14b, but I skipped out on the water cooling.
