Im doing the 3sgte swap into my 95 celica gt. Im looking at walbro fuel pumps, but I cant find any 255 lph specifically for 6g celicas. Will the twin turbo supra walbro fuel pump drop right into my tank? If not how much modification is needed? Heres the walbro part #GSS341 . Also, has anyone had the walbro fp fail on them. Thanks for any advance! <Brian>

Ouch, thats rough!


IIRC:
550cc injectors ~= 52 lb/hr @ 100% duty (~= 110HP each)
440cc injectors ~= 43 lh/hr @ 100% duty (~= 80 HP each)

4 x 50 = maximum 208 lb/hr @ expected fuel pressure rate
4 x 43 = maximum 172 lb/hr @ expected fuel pressure rate

Stock 7A/5S/3SGE fuel pumps are 160 lbs/hr @ 45 psi
ST185 fuel pump is 170 lbs/hr @ 45 psi
ST205 and 2JZGE are 190 lbs/hr @ 45 psi
2JZGTE is 250 lbs/hr @ 45 psi

So, if my 550cc injectors are running at 75% max duty rate, then the stock 160 lb/hr pump @ 60 psi should be within the upper limits of its capability. I'll be swapping over to a spare 185 pump later on for safety. With the amount of air I'm pushing with this turbo, the 550's are over-kill anyways.

I have the supra pump in my ST185, its nice and quiet. Plenty of fuel for 660cc injectors too.
We just installed the walbro into my buddies 7MGTE 4runner, and man its LOUD!

This is all from memory, so the numbers could easily be off. I had Denso's injector and pump specs when I worked at AP and I checked all of this out before, but I have no idea where they are now.
