Josh ur a top bloke..Thanks!

Don't know what the Stagea one is like to install, but obviously it would be different. Just as the Silvia one is different.

The Walbro is a lot easier to install than the Bosch that is for sure. Definetely not as easy as the Tomei/Nismo one given that you literally pull the entire old fuel pump assembely out of the fuel tank and put the new unit in and plug it back in and you are done.

The Walbros are a lot more sensitive to flow rates vs voltage and therefore some cars require rewiring to ensure they get 14V.

As I said, if you are confident in what you are doing get the cheaper fuel pump. I am just saying the Tomei/Nismo is worth the money given how reliable and easy the install is.

Your choice.

thinking if its possible my injectors are clogged or something..??

[rondofj]

Heard about the rewiring a lot, from where to where do I need to rewire - sounds like another pain in the a.. I think the walbros come with the short bits of wiring from pump to top of assemply plastic cylinder thingy.. Not keen on rewiring other bits of the car mate!

Everyone I know with a walbro pump just says they would not get one again..... I dont have any experience with them so can't really say they are bad, but going off what others have said I wouldnt buy one

They are not purely for a drag/high power setup. I have run one for nearly 3 years, from when the car was basically stock just before I got a tune till now, and I cannot fault the Tomei pump at all. It is near silent, has never had fuel supply issues, and only took about half an hour to install

Bosch pumps are noisey and have pickup issues

Walbro, from what I know, need a direct power feed because they only provide there rated fuel supply at 15v or something?

Like I said I dont have experience with these two, but just saying that I've never regretted paying a little bit extra for the tomei pump

[rondofj]

man seems like all these pumps have their own little issues..!

Anyone else think I need a new fuel pump?? Now I'm confused on whether I need a Bosch 044 or 040..

i dont think you need a fuel pump, i KNOW you need a fuel pump.

a 10+ year old fuel pump is just asking for trouble when you are giving it stick, especially if you have modified the car

just reading the Nissan Silvia forums, everyones recommending the walbro over the bosch

of course they are

For this guys power goals the walbro will be fine and wont require rewiring, I had one in my old gtst (270kw) and know plenty of ppl that have had them and had no trouble running them for several years with decent power. My best mate runs one in his 240kw evo 8 mr and has no troubles at all. As stated pay the 10 bucks extra and get the one from a vendor with the correct fitting kit so you know its genuine. There are plenty of DIY out there for fitting these fuel pumps and if your unsure ask someone thats done one or take it to your mechanic.

As for the nismo/tomei..whats the point in paying $600 odd for a fuel pump when his only going to be pumping out about 200odd rwkw...if he said 300kw i could see the point, The walbro/bosch will certainly be enough for his power. There a piece of piss to fit if you have half a braincell on mechanics or can follow one of the DIY threads.

[joeyjoejoejuniorshabadoo]

holy shit is that what they cost now?

i got my nismo pump 4 years ago for like $300

[rondofj]

Cheers Dan, my ultimate goal is 300rwkw - thats when I get the remaining 3 items - injectors, turbo and Z32, keep telling myself I wont waste money on these, but knowing myself, I know I will, lol..! ! So I guess the Walbro is not so bad - GAS Motorsport in Wetherill Park sell them (Walbro GSS342) for $115 -I guess thats a good price for a decent item. So it WILL support 300rwkw wont it?

And you said it for me - dont see the point in spending $600 odd for a bloody fuel pump, should be ok to fit - I did my FMIC, spark plugs, oil change and oil + fuel filters myself. Read the DIY on the Bosch 040 - seems the hard bit is putting the assembly properly back down the tank in the correct position in slot..

And Hamish, what does a 325rwkw GTS-T FEEL like on the road - compared to a baby 200rwkw?? Shits on pretty much everything? Hows the response from jab on the throttle etc..

[sinistaGTR]

If and when you want the step to hit 300rwkw you will need to do the rewire to give it the 14.4 volts but its not hard. And theres plenty of people out there running that power with them.

i got my nismo pump 4 years ago for like $300

+1

You can now get them for under $500 delivered if you look right.

a LOT faster

I had a Walbro running 200awkw. Rewired it to full battery voltage (at least two DIY threads in here or pay someone to do it) and ran 245awkw but now upgrading for RB30. If I were you and you want 300kw down the line get a better pump now and be done with it - such as this Denso:

[89CAL]

Yeah think about it with the future in mind like I did. $500 sounds like alot now but $700 is more for doing the same job twice (random prices I choose for fuel pumps)

[rondofj]

ok ok so do the Bosch 040s require re-wiring as well like the Walbros, once u go over a certain power level/flow rate... faark so hard to decide ha ha.. 280-300rwkw max goal - no nismo or tomeis please, just one simple reasonable quality internal pump....

[wolverine]

Bosch 984 will fit and you can use your old sock with some minor mods. This way you can get the pick up right at the bottom of the tank which can sometimes be an issue with 040's.

DIY section has a thread on this.

[Randon_I_Am]

I use the Walbro, put the stock sock on the bottom of it for better fuel pickup.

I'm running 290rwkw on E_Flex (E70, so 25% more fuel needed than with PULP98) with perfect AFR's before doing the direct battery wiring, but since then have done the direct battery wiring for peice of mind.

there's a lot of walbro hate round here. But for me it seems to be working a treat!

[scotty nm35]

Im upgrading to twin Walbro's soon by the looks of it, I will have my r33 gtr Tomei pump up for sale then, if you're interested...
