1999 miata w/ FM turbo kit and Garret 2560 with ms2 pnp and Flowforce 640cc injectors. Currently running 10.5 psi of boost.

So I've had 2 fuel pumps die on me in roughly 6 months. The first one was OEM and the second was the Delphi stock replacement.
I already tested both the main and fuel relays and they work fine (though I might upgrade the main to an 80 amp). I found that the plug going into the pump definitely gets 12 volts to prime when I turn the key, and the ground wire checks out as well, but the pump won't run anymore. So I'm trying to choose between the Wahlbro 190 and the DW100.

I want to avoid upgrading or destroying the fuel pressure regulator if I can. I've seen that people run the wahlbro in NA miatas without messing with the FPR, but is it fine for NB's to do the same? I also see a "high pressure" and a "standard pressure" option on fab9's website. Which would I need?

Or is the DW100 better? I've seen forum posts of some DW models failing and exploding pistons. Does anyone have experience with the DW pumps that can tell me if they're a good option or just pieces of trash that I should avoid?
