fuel pump for 5sfte, help Options

[JWalk1818]

Will a 93-98 Na fuel pump be enough for a 5sfte setup with fmu and 295 injectors, im scared the 255 TT pump might be too much!

[shid]

NO. All 5sfte setups need an upgraded fuel pump, NA or turbo supra is good.; its not like it pumps more than you need.

so n other words it dont matter if i got a 190 or a 255 pump right i mean i dont need anything to control it, the fmu will do that right and i wont run real ly rich?

[macavely]

you can also use the gt4 pump... thats what doggy is using i belive..

[shid]

Mac, can you answer his control question? The answer I have is, " I believe so" but I dont reallY KNOW... I know it's not good to get one too big, like 500 pounds lol but big enough and then some..

[macavely]

the fmu will handle the amount of fuel the pump is pumping... the reason for the higher flow pump is so that when your going to go lean the fmu can control the pump to pump more and not over load ...

[JWalk1818]

so do i have a fore sue answe that the fule pump will only do more as the fmu tells it o i wont runn to rich and bog my motor down?

[shid]

No,

you've apparently been running up to 13 psi without an intercooler or a fuel pump. No offense, but thats just asking your engine to be blown up.

[JWalk1818]

that answer dont make sense and yes i do have an intecooler, everyone on here wants to flame! ALL i want to know is if i install a 255 supra TT fuel pump will it put out more pressure than i need and run me REALLY RICH!!!!! OR will it e ok and will my fmu control it right with the 295 injectors and just add the extra fuel pessure when i need it. AND FOR THE SMART ***** out the i been running 10 psi not 13 ut i have hit 13 but i was running 115 mixed with 93 so it did not spark knock so stay off my back and dont try to answer questions when you dont even have a clue to what im talking about!!! THANK YOU AND HAVE A NICE DAY!!!

[shid]

Jason, I was not flaming you, if I wanted to flame you, I would have made an immature post filled with swear words like the one you just posted.

Instead, I'm just telling you that your engine WILL fail, and it will costs your hundreds of dollars if you run that high- even every once and a while- without low compression pistons, mild headwork, and a fuel pump. You can flame me all you want, but it's not going to change the fact that running that high on stock internals is asking for trouble.

get the walbro 255lph pump for a supra tt

its the fmu that creates the pressure by sort of pinching the fuel line as the pump keeps pumping

there is nothing wrong with having a pump taht can support 500hp on a 200hp application

i was told to get the supra NA walbro 255 pump for my swap. as far as i know, the na and TT pump is the same (255) but you need the NA install kit. i did mine a few days ago and had no problems installing it. my car is not yet running tho.

[rjbibeau]

you had no problems installing it. did you have to zip tie something like in the tt model?
