Where do i go to find an upgraded fuel pump for my turbo 2.4?
 

I need to upgrade my fuel pump so that I can make more power. Right now I'm maxing the stock one out. Anyone know where to get an upgraded one?

how can u be maxing out ur fuel pump at 260? Theres 2.4 on stock fuel pumps that are over 300

Maybe its my bad tune? I dont know that tuner that sucked at tuning my car originally told me my pump was at 100%. I would like to just keep it if I can. How much max power should I be able to pull out of this pump? I would like 350whp if possible on it.

Your pump should be fine. Who are you tuned by?

Tuned by a local shop here called asap with hp tuners. Would this product work for me? Are the 2.0 and 2.4 pumps the same?

you sould have a lot of room left on that pump, but you can fit the walbro 255 in your stock canister, but the stock pump will out flow the walbro at the pressures you are running.

thats good to know. I get back on the dyno on may 25th Im hoping. will see what happens from there. I bought the 2 bar map from you guys to help tune better.

get a inline fuel pump. I spoke with hahn about this.

Basically, the stock fuel pump would be used as a pass through.

Lets just say, your stock fuel pump was pumping 100lph.

and your new inline is 500lph. (obviously just using whole numbers for easy math)

I was afraid that the in tank 100lph fuel pump wouldnt be able to supply the 500lph fuel pump enough fuel, so in turn the 500lph would essentially be sucking air.

He told me that the 500lph would essentially suck fuel through the in tank 100lph. So it doesnt matter if it was a 1lph, or a 100lph. The larger of the 2 will be doing all the work.

So with that said, any universal pump would work just fine.

you sure he didnt say fuel injectors at 100% cause that would make more sence

100% fuel injectors would be more reasonable. but i wasnt aware there was a way to test the fuel pump's percentage other than watching your fuel pressure gauge to see if it peaks then drops.

well I have 60# injectors so they should be adequate. we had a fuel pressure gauge hooked up and thats how he thought it was determined.

Celica, the easiest way to know is this.

Watch your fuel pressure.

If it peaks at say.. 100psi..then drops from there on out. Your fuel pump is maxed out.

However, with that said, make sure its not the tuning that's causing that to happen.

yeah, so far i will be getting retuned by a better tuner on may 25th. if my tranny is in soon and i have enough time to get my boost controller installed and my wideband.

im still trying to rig up the hahn kit in such a way to work with my boost controller..successfully.

the car spits/sputters if i floor it and i wont get full fuel pressure.

i have to partial throttle...then wait till fuel pressure rises, then gun it.

did you disconnect the fmu or you still running it?
