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.

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

[

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 :rolleyes:

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.

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..

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:

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....

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!

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
