Hey everyone

I wasn't sure where to post this, but since im from vic, i thought i'd ask someone from vic. lol. Im looking at buying an aftermarket fuel pump for my r33 gtst which needs to be able to handle a fair amount of power. I was recommended by autobarn to use a bosch 044. I don't know much about fuel pumps. i believe these are external? I've been told by friends that these can be quite noisy. Could someone explain wat that means. Also last night i was told that i would be better off getting a Walbro fuel pump. Are these internal or external? Wats the best thing for me to do. I didn't wanna spend more than probably $250. Just not sure the best option to go for. Any help would be very much appreciated.

Cheers

Guesty

044 is external. unless you're intending to output over 350kw at the wheels i would stick with an internal bosch 040, which you can buy for under $250. Walbro's are shit dont bother.

any particular reason why you say walbro pumps are shit?

actually...i brought a bosch 040 for my r33gtst, the workshop told me to get rid of it, hard 2 put in, surges around corners and to put in a walbro...said there much better...this was from a respected performance shop...havin already brought my pump i decided to go my own way and put the 040 in.....works fine, lil noisy

Walbro's are good in respect to fitting and noise but definately not reliable....I have 2 cases which burnt out with in 6 months

Bosch 040 is good and reliable, little harder to fit and probably wont sit far down in the tank...so if your low in fuel you might get surges

any particular reason why you say walbro pumps are shit?

unreliable, know of 2 people who've had a walbro "500hp" pump fail on them and they were supposedly genuine pumps.

the walbro pump is physically smaller than the bosch 040. the bosch IS a prick to install, but remember that if you go for an external pump you will also need a lifter pump inside your tank regardless... certainly not a $250 excercise.

the walbro's are rated at 15volts in the r33 they only run at 12volts so they never run at their optimum charge, hence "they're crap" run a 15volt direct circuit to them and they should be OK.

skyline r33 gtr pump should be fine for your requirements and is a direct fit. the bosch is only noisy if installed incorrectly. normally it should be quiet

hey GuestyR33...

i've got a Bosch 040 for sale if you're leaning in that direction - never got round to fitting it and i don't need it atm. here's the link to my post:

/end shameless plug :)

Well from the sounds of it

Im leaning towards the Bosch.

Fitting hassles are neither here no there.

Wat else do i require if i fit say an 040 or 044

When u say there noisy, wat do u mean. Wat kind of sound, is it loud. Can u here from cabin. I've just never seen one of these installed.

Thanks everyone for your speedy replies.

Been a great help.

I have a Bosch 044 external installed in the boot and it is pretty damn loud, but i have gotten accustomed to the sound :lol:

Ever hear speaker noise from a stereo system with earthing issues or rca's running along side the power cables? Well the sound is similar to that but deeper and a little louder. Definately heard inside cabin, and over a loud exhaust.

The Bosch 040 are alot quieter, and can only be generally heard while primming the engine b4 start-up.

    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
    • Assuming your brake pads are not worn right down, I'd add a little brake fluid. Is there any sign of a brake fluid leak?
    • Hello all,  I need of some help. On my drive home my handbrake light lit up and started flashing. When I got home I checked my handbrake sensor under the centre console and nothing seemed out of the ordinary. I have scanned my car via the consult port, no codes shown. Checked my brake fluid as well which is half full. Tried unplugging the brake master but it didn't change anything. Thoughts on what it could be? The master float doesn't seem to be stuck. My car is an 1998 ER34 sedan GT. No hicas but has ABS Photos below 👇🏾
