Default Fuel Pump question

hey guys.. The turbo that i will be running is a sr20 T25 and I plan on boosting around 7 -8 pounds daily. The question is.. do i need the 255 fuel pump or the 190? and also.. i was looking for a reputable site to purchase a fuel pump but couldnt find one. Can someone post a site where i can buy whichever fuel pump you think i should get? thanks

Anybody know if the 190lph-HP works for the 99+ NB miata too?
I know the newest fuel system is returnless, but the pump should work, right?

You don't need a high pressure pump in your NB since you're running big enough injectors and an EMU.

People have reported that the NB's pump can't hold 60 psi under load.

yes it does work, I've got a 190hp pump in my 99 and it used to have a 255hp (moron previous owner) that worked fine too.

C'mon. You HAVE to have a return fuel system in an NB to run more than 180 whp. POPSTOY said so.

Ahaha, you guys make this forum so much fun than miata.net

So a 190lph-hp isn't worth on a '99 nb?
Do you think that making the dual feed mod on my returnless fuel rail (removing the pressure damper) and keeping the stock fuel pump will be ok for 200-220whp?

If I had the returnless fuel system, I would try to come up with a way to put a pressure/boost sensitive FPR in the back and rip out the OEM setup. Surely somebody with an NB and turbo has looked into this. Running a vac/pressure line is much easier than a fuel return line.
