walbro's are crap, bosch much better

Its funny how someone can just say its crap and not explain why.. Seriously whats the point of posting.

I have had walbro pump for 2 years now and never had a problem. Its still going strong and i just recently tuned my car and still didnt experience any problems..

So why would someone say its crap?

care to explain, coz i wanna know

Sometimes people repeat so much of what they hear on the internet as gospel with out any first hand experience it's rediculous.

I'm not saying Walbro's are the best, but I personaly know of 5 cars running a single Walbro over 500hp (at the motor) that have been doing it for over a year or two or three. One of those guys was running a TO4z and making around 600hp at the motor with a single Walbro, and he used to see a bit of pressure drop towards redline, but the car ran like that for a year. He's running a dual Walbro set up now. Would I run a Bosch 044 over a Walbro at that level? Probably. Will a single Walbro be fine up to 550hp at the motor? I'm betting my motor on it, and have been doing so for 2 years now.

i got a walbro pump for $160 new and paid RE customs $80 to fit it.

good pump so far, i was told not to let the fuel drop lower than 1/4 tank as the walbro doesnt reach right to the bottom.

As was mentioned in a similar thread Walbro pumps suffer volume wise at higher fuel rail pressures - ie on a forced induced engine . You can put this down to the "high pressure" relief valve settings these pumps have .

The real question is are people continuing to buy these pumps purely on price and if so how much more does a more appropriate one cost ?

My R33 GTR pump 2nd hand owes me $100 and there's no way I'd swap it for any Walbro out there .

Be VERY wary of Walbro pumps on E bay or shady suppliers because there a Chinese copies out there even worse than the original .

You're lazy = Tomei/Nismo

You're a DIY freak = Bosch

IMO the more expensive ones are more reliable and easier to install. Walbro has been said to lean out at high RPM. I spoke to a tuner who said he doesn't recommend Bosch for R33's because they don't sit all the way to the bottom of the tank and it's risky business (i have the 040, just don't drain the tank to be safe).

Depends on your budget, if you want to DIY and save cash, what power levels you're aiming at.

Figure those out and the choice should be easy.

G'luck.

It's power levels that lean out a fuel pump, so high RPM on a 400hp car ain't going to lean out a Walbro. My friend with the TO4z, however, did see around a 5-10psi drop with 600hp. Still nothing that's going to turd a motor as long as the injectors can keep the motor fat and happy, but on the edge no less. I have had no problem for over 2 years with 430hp up to around 550hp (at the motor) running up to 1.8 bar.

I have never seen anybody on island here have a Walbro go bad, but I'm sure it has happened. Pretty much everybody here uses them, however. If I ever get my hands on another Holset HX40 turbine wheel/housing, I'll probably throw either another walbro in there or get a Bosch 040.

Check this thread for Nismo/Tomei info :

Heaps of pics on page 1 from the original poster, plus heaps practically showing the full install on page 2 by me

If you planned on paying someone extra to install, check the above thread, pay the extra for the full kit and do it your self.

I had a GTR pump with brackets n stuff.

Took it all out

Removed the stocker.

Scratched my head a bit, and put it all back together with the stocky, i couldnt' risk it not working as i commute in this car, and i wasn't confident in my own skills in hacking this together

Sold it, bought a Tomei and did the swap in like 40 mins.

NEVER had a problem and it was SOOOOO easy !

You don't need anyone to help installl these babies.

So yes, they are the lazy way as stated previously....but just cause it's easy, doesn't make it any worse than the rest.

These are better than Walbro's and most Bosches.....

So yes, some wiring is changed in the kit.

Just do it already, check the thread and the pics.....

I found the Tomei kit cheapest thru Greenline ($50 cheaper than Nengun)

$340 at the time which i think are closer to $300 now....delivered

It all comes down to what money you want to spend, what power you want out of your car, and how easy you want the exchange to be. I think most pumps that people have mentioned will all do the job you are after. I have an R32 GTR so not too sure what if any differences there are in the fuel pump setups between models but speaking from personal experience, I would not use Walboro again. At the moment I have a HKS item (was the biggest intank item I could find at the time which flowed the most) which comes complete, plugs and all and was a direct swap for the original. Simply slide the old pump out of the cradle, disconnect it and slide the other straight in. Connect the plugs, lines etc, slide in the cradle, back together and away you go. I am currently supporting 341 kw's at the wheels and no problem with lack of fuel.

At the end of the day, do the research, way up all the pros and cons (cost, ease of install etc.) and make your decision. Good luck with whatever way you go.
