why not use a single Walbro 400lph jet pump? unless you need the extra 100lph for some reason..

even then, I'd use the 400 and a bosch 044 in-line or something.

shud i go for dual walbro or one bosch 044 pump ?

 

[Dylan JZ]

Single Walbro 400lph turbine pump.. not sure how else to phrase this.

Single Walbro 400lph turbine pump.

This, or use an aeromotive a340 stealth.

Okay so I'm looking for 500 whp out of my 1jz
Walbro 400lph turbine pump or aeromotive a340 stealth??

 

[Dylan JZ]

Easily both ways.. But the 400 is a safer bet for 500-600.

After that, twin a340s, twin 400s, or either one in combination with a Bosch 044 inline would be the ideal setup IMO.

What hp is a single walbro 255 good 4?

What hp is a single walbro 255 good 4?

good question I think I'm close to 390whp with mine.

 

[IndigoMKII]

Or go A1000 and call it a day..

It's more about how much fuel it's putting out than a specific HP, but I'd say around 450whp is a fairly safe estimate, though folks do/have done 500 on them lol.

 

[Dylan JZ]

Something to keep in mind is what fuel pressure is at, what rail and lines are being used, and ultimately which injectors. That all might seem like common sense, but each one is an important variable that modifies what is needed.

 

[jdmfreak]

Lol good thing i stumbled on this thread lol i was under the impression that a 255 was good for 750 injectors... and 750 injectors were good for about 650 rwhp with no j tube and a afpr ... guess i should look further into some of this stuff before just beliving what i hear lol

old thread, but im trying to find a answer.

will 2 400lph fit with minimal modification to mk3 hangar? i have one already but im shooting for 600 on e85

 

[GrimJack]

No. The only pumps you can put in two of that I know of are the Wally 255 or the Aeromotive 340. Even these are a DAMN tight fit.

The Wally 400, Denso Mk4, and Bosch 044 are too large for two of them to fit through the hole in the tank.

 

[1986.5supra_kid]

Time to research surge tanks then huh?

Or go A1000 and call it a day..
