I am looking for RRFPR rising rate fuel pressure regulator for my turbo 2.8.
I found this one from Holley Part #: 512-505

Fuel Pressure Regulators – EFI
Boost Compensating Universal EFI


This Fuel Management unit is designed to run in conjunction with the factory fuel pressure regulator. This is the ultimate manual fuel management control unit and is installed in series with a stock regulator in the return line back to the tank. The unit increases fuel pressure in proportion to boost pressure up to a 4:1 Idle/WOT pressure ratio depending on which included adjustable disks you select. This add on upgrade is ideal to be used with aftermarket turbo and Supercharger kits that require additional fuel pressure volume as the boost pressure increases. This unit is
adjustable from 20–75 PSI, offers two fuel pressure slope settings and is recommended to be used in conjunction with any Holley High volume EFI fuel pump.

Is this the right one?
Do you recomend this one?
Any others that may be better?

Thanks

I've searched and found a lot on adjustable FPR, but nothing specifically for rising rate, turbo applications.

I use one of these.
A little touchy but they work good. You'll need a high pressure pump.

thanks, looks good.
What part number did you go with?

Bought for 2500$ Canadian.

I think it's a 2025 and I bored the fittings out a bit to open them up. Back when I bought it it was called a Cartech. Pretty much the same unit though.
Oop, wait...here's the Cartech website now.

The same unit, except for the needle valve. I like the BEGi's one better, since the Cartech's needle valve gave me trouble early on..
