Biggest Fuel Pump in stock Unit?

So I am scrounging for sources of people using what fuel pumps in the stock S1 fuel pump assembly. I see small guys installed but this will be for a REW swap. The best solution I have found so far is the 340 stealth but that is a bit small for my goals down the line.

So my question is what is everyone running? Or if you know of good links to which buried in build threads that would be awesome!

Thanks

Stealth in drivers side, stock in passenger side, Bosch 044 in surge tank.

Don't really need the stealth for a pickup pump...but didn't bother taking it out

S1 Stock assembly simply sucks and changing the pump will help but not too much, rew in stock was a 200 or 185 lph pump i dont remember, so its probably better just do what dannobre did

I'm running a DW300 in the s1 assy . It is actually too big as I initially got big pressure spikes at the point where the 2nd stage kicks in . Was able to fix that by drilling out the siphon.
