Where can i buy that Walbro fuel pump for turbo 2 rx7. Also which model exactly do i need, and how hard will that be to install?
Please reply

 

I beat Ted!

www.k2rd.com I think around $130 they have a kit for 87-88 and 89-91. it's not that hard.

 

is that pump any good and if i have bonez intake,fcd, catback, midpipe and want to run around 10-12 psi , would that pump be good, also i'm planing to get FMIC later. Is it safe?

 

yeah that should be enough for the boot you plan on running, but thats all you can run. besides thats all you need to run, any moreand you would be over spinnng the turbo and just tearing it up. you can also get that fuel pump at www.rx7.com its RPs website.

I wouldn't be running 12psi off just a pump. set it at 10 and get some wide band 02 time. and slowey move up and see what happens

 

the fuel pump at rx7.com goes under different name, i dont' know if those are the same or not. if they are not the same which one is better for me to get ? Also what is that mean O2 time?
Thanks a lot

 

the one at Rx7.com would be better since it's a NipponDenso. it will probably last longer, and it's quieter. however it's over 2x the price. interms of fueling they wouldn't be much different.

 

Will i need to upgrade my injectors or will my stock 550cc be able to support this new pump? I don't have any money to upgrade my ecu or something like that so will this setup be able to work without any damage to engine?

 

it won't do any harm. but it's not your answer to unlimited boost. as I said before I wouldn't trust a pump as your only fuel mod over 10psi without getting on a wide band O2. it's a device that will tell you if you are running rich or lean. the good systems cost a couple grand. A local dyno shop probably has one. probably charge $100 or so for a few runs. much cheaper then a new engine. if you're running ok at 10psi, then move it up a bit before the next run. when my car's back on the road in the spring it's one of things on my list to do.

 

i got a/f phantom gauge that shows me rich or lean and right now with the stock mods i'm in 2nd green lead, which is rich. Is that any good? I don't want to blow my engine, i will buy that pump and with the mods that i have now, i will probably be in 10psi which is safe. What else do you recomend that i should get for like 12- to 14 psi. ?

 

You will run rich with the walboro, get an APEX AVCR and lean your maps out.

 

is that apexi avcr and apexi afc really neccessary? can i do this setup without it?

 

You can't you're fucked really. Get a rail from www.krd2.com and new injectors. Possibly a fuel controller, like the REBRIC IV. Going with just a fuel pump upgrade will richen up your mixture and make your car run like ****.

 

so the point that i have bonez intake and catback, mid pipe, fcd and that common ****, means nothing? If i get that walbro fuel pump without those two apexi things i'm fucked????? Isn't bonez intake sopose to give more air so that i will need more fuel? Is that true?

 

No were all fucked, this thread has gone to hell. Get the fuel pump and see how rich you run. You will still need a way to control all that fuel. IF you want your car to run right. The fuel pump is just a bandaid for the limited fuel system. It does nothing but buy you time.

 

Bump

 

All i want to know now is this setup safe and will it blow my engine or somethin??? I have Bonez intake, FCD, Catback, Midpipe. If i was to put a walbro fuel pump in with the rest of the stuff stock will i be able to run 10 psi without any problems????? That's all i need to know, Please reply

 

Doh!

The Walbro can easily support 300hp to the wheels.

The stock fuel injectors can only support 250hp at the FLYWHEEL.

This should support almost anything the stock turbo can throw at it.

the fuel pump will not do any harm, and will be fine for 10psi as long as everything else is running good and tuned up. plugs, wires, fuel filter, etc.

wicked7 keep your month shut as you don't seem to know anything.

 

thanks scott, i'll do this and see what happens.

Thanks a lot

 

I found after the pump install, that the motor liked the same correction factors on the s-afc that it did with the old pump, nothing really changed to much as far richness, although, when I did start playing with the s-afc, one adjustment point made alot more of a change than with the stock pump, I would have to say you can run the walbro without an s-afc, you may get a bit of overfueling at certain spots, but nothing major showed up on my car with the safc set at zero correction factor..

The RX7.com pump is the 3 rotor cosmo pump.

 

it's a supra twin turbo pump...

 

in that case go search for a used tt supra pump. they go for 150 used
