I really need this, Im looking to pick it up ASAP, it is the last piece I need before my swap will be completed. Anyone help me out?

just buy a walbro and be done!
lol

Isnt the walbro 1 stage versus the 2 stage stock ST205?

Supra turbo pump ?

If the walbro's 1 stage is stronger than the 2nd stage of the 205 whats it matter? Just make sure it's getting the full voltage all the time (wire it correctly).

I have a lightly used walbro 255 lph fuel pump for sale. Less then 1,000 miles on it. Only reason why i dont need it is because im upgrading to a walbro 485. Need a bigger pump for 500 whp on e85! Ill sell it to you for $60 shipped. A walbro 255 will easily be enough to a little over 400 horsepower on pump gas and will flow better then a st205 fuel pump. Your other option is a factory toyota supra twin turbo pump. It is quieter then a walbro pump(walbros make a distinctive whining noise) but it is three times the price of a new walbro.

The fact is that the two stage ST205 pump will not force feed the motor a ton of gas on the stock ECU at all RPMs. I dont think the Walbro will work in the same way the stock ST205 pump would.

These engines are not return less, any excess fuel is pumped right back to the tank. I ran a supra tt pump on my car for two years not once was it running ritch at idle or part throttle.
