Oil pressure on these engines is 7-10 psi at 3000 rpm. I don't know of any turbos that like oil pressure that low, even if contaminants aren't a problem. Any kind of hiccup at that low pressure & who knows what will happen.

I think I would want to fabricate a system with an electric pump capable of about 30 psi. A seperate resevoir of maybe 16oz. along with a small cooler & a timer to maintain oil flow for 30-60 seconds after shutdown would insure the turbo a longer life.

Of course if you know of a turbo meant to operate at that low oli pressure then-----never mind.....
