Will feeding the turbo with a separate pump solve your pressure problem? RB Racing looks like they have good pumps for the turbo. They're low flow compared to a fill engine pump, though.
I thought it was the other way around for pumps. Hence the low flow, high pressure fuel pump feeding the DI system while the high flow, low pressure pump feeds the port injectors and the high pressure pump. Make sure the high pressure line has plenty of supply via a low pressure, high flow pump.
But I'm sticking NA for now. You're the one with a problem to solve and money to make.

I think something like this would best used to feed the turbocharger so that's one less thing the main pump needs to feed. The temperature limitation is a problem however.
