Hey,

Just wondering how far a standard r33 rb25 (ser2) fuel pump will go?

Currently running the following setup: 3" exhaust, FMIC, std turbo, std injectors, remapped ecu and 12 psi.

Will it handle this ok?

cheers

matty

Probably yes, but due to the age of the car and the pump i would be looking to invest in an upgrade at some stage just for safety anyway.... They are cheap and easy to do so no reason not too :)

hmmmm good point.

Whats the better setup in a r33?

Bosch 040 and remove the sock, mount pump as low as possible

or

Bosch 044 and adapt the standard sock to fit?

i did a 040 years ago and remember not being certain that I had it mounted as low as it could possibly be and from memory i recall seeing a 044 mounted in tank with factory sock....

How much power are you aiming for mate? Drop in Walbro will be much easier for lower power levels....

My 044 is mounted with rubber on the bracket and has a sock, better than the 040 option but depends on how much you actually need?

ive had 2 walbro's now, the 255Lph handled 260kw so that would be fine.. quite cheap too. I didnt want to take chances with the fitment, tuner fit mine in well under an hour so worth it to get done right first time.

Walbro have a good rep, with the Bosch pumps Ic heard good and bad things. Seems they can go either way depending on batch etc. I recently bought a Nismo and couldn't be happier. I'm letting a GTR pump go. PM if interested, I want it gone!

What bad things have you heard? Been pretty reliable from my experiance and many many others...............

Not saying they're all terrible, but as I said I've heard a few can be dodgey and have ha to be replaced. Read it in a couple of threads here on SAU, but as I've said I'm not commenting on personal experience just what I've read on here.

I've had a Walbro in my tank for about 4 years. I have a 044 as well - haven't heard anything bad about them except they're noisy as!!

Mine is quieter than the 34GTR pump I had.... All about how you mount it etc

    • Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in
    • Let's just fix the problem by f**king the rest of the gearbox.
    • Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
    • How much does the shifter move when the car is in gear with the engine off? If it is more than about 1cm you need to replace your shifter bush. Your shifts will just get crunchier, not faster, with a short shifter unless you also rebuild the whole box
    • I should video mine, will prob do it tomorrow    Between 1st and 3rd, you could fit another two gears. That is how loose and wobbly it is   horrible:(
