Does anyone have some specs on the required oil flow for lubrication of a turbo? Or perhaps some numbers on what the stock WRX/legacy/etc turbo oil flow is?

Thanks for the help

Do you mean the oil pressure or the actual oil volume?

I'm looking for the volume flowing through the turbo.

I am mounting twin turbos on the SVX on the bottom side of the engine, so I need a scavenge pump setup.

I'm trying to figure out if I need one or two scavenge pumps to suck the oil back to the topside of the engine.

if you send me specs on the turbo i can calculate all that.

mechanical engineering degree coming in handy every now and then.

Heh..I got one of those too :P

Oh what I mean by volume through the turbo is the oil volume, not air volume. Should have made myself a little more clear there :doh:

Any findings? Do share them :)

Well according to Mr. MacInnes, a 3 inch turbo would require about 1/2 gallon per minute of oil, and a 3.5-4.0" turbo would require about 1 gallon per minute. Using at least 30psi of oil pressure in both cases. This is for single turbo apps.
So my advise to you, shoot for a 1 1/2 gallons/minute and play it safe.

oh yeah:
