Depends on your fuel rail pressure. For anything under 68 psi the Supra/Denso "195130-1020" pump flows a little more than the 255 High Pressure Walbro pump. Since stock FD's only push 36-38 psi base fuel pressure you would need to run 30-32 psi of boost to see 68 psi at the fuel rail. With that in mind and a stock FPR the Supra/Denso pump would probably be the better choice.
One thing you need to know is that a Supra/Denso pump pulls almost twice as many amps as the high pressure Walbro. They need a stout power supply circuit if you want their full potential. We're talking at least 10 gauge wire straight off the battery with a fuse and relay capable of dealing with 30 amps (even though you probably won't see more than 16-19 amps maxing out).

If its to complicated I dont think I'll go that route then, I mean if its not that much of a difference between the supra denso and the walboro, I guess I'll go walboro not to mention its cheaper to.
