Hi guys,

Couple of interesting alternatives are available atm to the usual Walbro GSS-341/Bosch 040 options:

AEROMOTIVE 340LPH 340 LPH 90PSI HIGH FLOW FUEL PUMP

These are pretty new I think, looks physically almost identical to the Walbro, claimed 340LPH flow, available on (ebay) here:

http://cgi.ebay.com/...n#ht_4609wt_933

some Supra-related info:

http://www.supraforu...w-charts-review

...and...

Deatschwerks DW300+

These look promising and cheap at $169 US thereabouts (considering the exchange rate)... claimed 300+ LPH.

http://www.deatschwe...-tank-fuel-pump

Look like the Walbro pump again, no Skyline-specific model fitments listed but here are the physical dimensions:

Anyone used either of these? Anybody have any recommendations? I don't know where fuel pumps are really at these days... everybody still use the Walbros, or...?

cheers

One thing about both of these models is that they claim significantly higher flow rates than the walbro (300-340 as to 255) which I believe has poorer flow rate performance unless it's hard-wired anyway (though to be fair probably all pumps do?). Just something to consider...

the main thing to remember is that the c34's don't have a cradle like the skylines but instead have a box that clips to the bottom of the fuel tank

so going any bigger than stock will be a big pain to fit nicely without hacking up the box

I was looking to run one of these but they were twice the price and they also draw twice the current. I came to the conclusion they are great if you cant fit twin Walbro's in, as the twins will flow more at a similar current. Of course not too many people will need a 1000hp ethanol system anyway.

Tom, that plastic box looks very similar to what the m35 has. It may not allow enough fuel to enter the container if you run the larger aeromotive pump as I have found with the twins. Its only a problem at under 1/4 tank.

So lets throw an ace in the pack hear

2x walbros = what..? 510lph?

To burn even 1 full capacity of a walbro you wd need serioisly big inj, running huge duty cycles.... With a tune and car to suit....

Why in gods cock would u need anything more than the quiet, easy to install, cheap, more than enough flowing walbro...:)

because they only flow 255lph at some shitty low fuel pressure

ah just found the chart, they also only flow 255lph with no fuel lines attached, Ill assume the Stag lines are 5/16" same as the Skylines...so try and blow 255lph through a long maccas straw.

please show me how it would be benefitial to have 2x walbros...

stock 25 inj run at 370cc... so all 6 at 100% duty (never come close to that safe) is 2220cc/per min...

1x walbro flows with no lines at 4250cc per min...

even half the flow rate for lines witch would never ever happen... and you could still run your injectors at ~99.6% duty... if someone was stupid enough to run this higher %. they deserve to be kicked in the head lol....

scott upgraded the fuel lines to braided SS , pressure reg, and 1000cc injectors.

hence: beneficial to have teo walbro pumps.. the way its set up is, one pump runs one fuel rail(theres two as v6) so makes if efficient!

1000cc is just the spec of inj....

what sort of duty is he running... all these mods mean nothing more than the amount of fuel the car ACTUALY chews per min...

im not saying what hes done is wrong or right... just wondering why he has done what he has more than anything.

and wouldnt the braided lines flow much better than stock...?

having 6000cc worth of inj

and 8500 worth of fuel suply,

at 100% duty. he has 30% or so too much fuel b4 the lines... leaving him well ahead.

what sort of % would he run?

he maxed out the fuel lines on the last run. with the gtx going in he wanted to be safe so he knows that atleast his fuel system will be able to cope.

i think i recall him saying that he had already made the twin pump setup before he found the problem to be the lines, so he used i9n anyway.

but can definitely see your point.

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
