lp or hp 255 walbro fuel pump?

[awdwhip]

im gonna purchase a fuel pump today but im not sure which one to get. low pressure or high pressure? im gonna use it with a stock fp regulator and a gt30r turbo. im also buying 650's and an s-afc II. let me know. thanx

Get the high pressure one it will save you upgrading latter on, high pressure only flows more in the upper PSI..

thanx paul. anybody else wanna trough in their two cents?

Same answer as paul, the curves on both pumps are very similar up to 60 psi, with the hp being just slightly more. The difference is that the lp flows drops off right around 60 psi & the hp keeps flowing. You should probably look at getting an adjustable fpr as either of these will over run the stock one. Their usually the same price, so go with the hp, if you ever plan to run high boost, it will keep up.

GO with a denso supra pump, much quiter & better build quality.

i wouldnt go w/ the denso supra pump just because the fact is your not needing way too much fuel. but yes go w/ the walbro 255lph high pressure pump, you wont be dissapointed, and ive never had a problem w/ them.

I agree once HRC shipped me the Walbro 255lph I could definitely feel the difference over stock especially when the T kicks in.

i always thought the warblo(however you spell it) and the denso(again,...spelling) were the same,.....o well....

Both will over run the stock fpr, you will need a afpr either way.

You felt a difference? The only difference you could possibly feel is the car losing power due the engine running rich.

He might have felt a difference if his car was starving for fuel and he added a higher flowing fuel pump and an afpr to compensate for that! Without knowing what was done to his car, or what problem he had before hand, you can't really say that he didn't "feel" a difference.
